YTO / HP 5086-7781 & Introduction rehashed (just incase)
Hello group,
I can't remember if I have introduced myself in the past or not.? If my memory serves me correctly I might have.?? Just to be safe,? I am Jon, and reside in Texas, USA.? Passion and profession is electrical engineering since I was very very young.?? I have 40 plus years of experience in the industry and to this day, love this great & challenging industry.??
Anyway,
So I have a really good instrument that has suffered an early case of YIG-Itis.? I am looking for another one as a spare or would like to know if there is anyone on this forum that can sufficiently replace the output / oscillator transistor on the YIG I have.? If not, I am contemplating the idea of entering into the wirebonding process myself.? I realize this is not a endeavor for the faint of heart, but again I do like challenges.? ?In my opinion, this is probably one of the best series of HP equipment manufactured when HP was going strong.? This machine is way to good and young in life to retire it.? :)? Please, if you have a resolve feel free to contact me via email or on here.?
Thanks so much,
Jon M.

Re: E4401B No 50MHZ Cal signal
Hi Mike,
I do not have my CLIP (it's at work) but I recently repaired a couple of these ESA's, although different issue. (LO UNLOCK error)
As I recall, the 50 MHz is generated by a dedicated PLL that also generates the 10 MHz reference. I think it's a 100 MHz PLL that's
dived by 2 and also by 10. The 1st step is to verify the 10 MHz out is present. (back of the unit) Then use the I/O menu to enable the
50 MHz. If that is not there, you have greatly narrowed down the problem to that divider.
It sounds like your YIG is OK. Otherwise, you would have other errors. ("LO" unlock or too low or both)
Hope that helps. I can make a better guess when I look at the CLIP files.

Re: E4401B No 50MHZ Cal signal
I¡¯m just trying to get the unit to do its own automatic internal alignment by doing selecting the ¡°system->Alignment->Align Now¡± menu option.? I am not tweaking stuff manually.? I know the perils of trying to adjust or align things without
the proper equipment or documentation.? I have done alignments and adjustments on radio equipment, in the past and have the equipment to do so.
?
Unfortunately, for the unit to complete this process, it needs its internal 50 MHZ calibration signal, which is not getting generated.? Without it , during the automated alignment process, the unit increases the gain in the IF module to
the point of being unusable.? This is the problem I am trying to solve.? Does anybody have any idea as to why the internal signal is dead?? My original post outlines the diagnostic tests I¡¯ve done so far.
?
?
I? have to agree with Peter,? please do not adjust any of those "loose screws"? it will be the end of life for that one unless you're ready to get real serious with band pass filtering
alignment and the likes.??

HP and Tek CRTs at Stuff Day, April 13th
In our quest to make a lot more space, we are blowing out our Tek and HP CRTs at stuff day. Any tube, just $10 each.? In just ONE room, I found all of these types, and there are two more large areas to check. Virtually all are tagged good, some may be unknown.
?
Tek CRTs:
154-0677-10 (475), 154-0850-01 (many 24xx), 154-0910, 154-0969, 154-073-04 (Dual Beam)
plus several small Tek CRTs, and there's at least one -0644 type in storage.
?
HP CRTs:
5083-0952, 5083-2570, 5083-1622, 5083-3853, 5083-4052, 5083-2322 plus a 1740A CRT and several complete (new) magnetic CRT assemblies both mono and color.
?
There are also many Philips/Fluke series CRTs for their analog and combiscopes.
And we have standard EIA CRTs from 1EP1 to 7JP1 in stock, lots of 3RP1A's.? sadly, not $10, however.
?
I can hold them for you if you are coming up, or if you want to arrange with somebody like Bruce Lane at Blue Feather to pick them up for you for a small fee.? No, I really can't ship them, everybody grumbles about the high shipping cost, regarding which I can do exactly zero,, and the last two weeks to stuff day are beyond hectic for us. Don't for get all the manuals by the pound!
?
I hope you can join us for stuff day, this will be a truly epic event.? details are here:

Re: E8357A upgrade questions
If this were a SATA drive, you could use something like this:
Of course, the older PNAs use PATA drives, so you would be forced to use two converters.? I don't know if they make a similar device for PATA drives.
Regarding the display, I recommend this modification if not already done:?
Installing SP3 should work, but if I remember right, it uses a fair amount more memory...and you are already maxed out at 512MB.? As long as you do not have it exposed to the Internet, I am doubt it is worth the effort to upgrade it.

Re: E4401B No 50MHZ Cal signal
Hello Mike,
I would first check out that Local Oscillator, I suspect your's is not there.? If I recall the cal signal is derived from the root source (YIG LO) which is fed as a reference into the 1st converter? via direct or through a LO Distribution amp.? This LO rhythm needs to be around +12 to +15 dbm in level.? Best of luck!

Re: E4401B No 50MHZ Cal signal
The only advice I can offer is not to adjust anything until you fix the problem. I don't have this instrument. Hopefully you have a good block diagram and a description to figure it out. You are lucky to have the schematics. Peter

Re: Replacement battery for 8566A
I'm surprised no one mentioned my post " 8566A Battery Replacement" in the files section. The file is "8566A Battery.pdf". Recently (last few weeks) uploaded, there was a notification.There is a complete description of my modification, cautions, 8566A battery circuit analysis, schematic and pictures of the board, and mention of a resistor that goes nowhere in the battery circuit. The original charging only happened when the instrument was ON. This mod charges when the 8566A is plugged in.? If there is something wrong with my modification I would like to hear of it as it has been in there for several years. Feel free to add any other related documents to the file.

Anyway there is plenty of room to add a battery carrier of your choice! I guess and now you have a spare HP battery you also have the perfect excuse to get an HP45 calculator, re-discover the joy of reverse Polish notation and wonder how the heck you were ever able to read the display without a microscope......

Seems like the most likely explanation. So with that settled, what would be the best option for retrofitting a modern battery? It sounds like any other option other than the original nickel-cadmium pack will need a diode for protection.
As it happens, I already own a number of HP RPN calculators (voyager series though). HP-45s are a lot cheaper than 35s on ebay too...

Re: E8357A upgrade questions
Hi, If you already speak linux/unix - I've successfully cloned the disk on a E8358A by booting? a linux live image from a USB stick and dumping the drive contents via 'dd' to a further USB connected HDD.
On Fri, 29 Mar 2019 at 17:23, Pete Manfre < pmanfre@...> wrote: I have a drive clone device (stand alone ) that worked perfectly on the e8357a and e8358a hd's that Caesar graciously?gave me over the years.? ?I will dig up thename and model and post it when I fine it in tbe basement.?
Thank you again Caesar.?
Pete wa2odo As a follow up, Caesar helped me updated my PNA to the 500MHz CPU and 40GB HD. The machine runs way better and I can keep a USB hub (Keyboard and mouse) connected full time. The original 266MHz CPU was sluggish and wouldn't boot if a USB hub was connected. I tried multiple hubs to no avail.
Drive Ceasar supplied has XP SP2. Not sure if SP3 will work or provides any improvement.?
It took me a while to get the floppy to work. It seems it only likes floppies formatted by it and it may have had dust inside.?
You can use an external VGA monitor if you use the display driver utility to enable it. If the external monitor is disconnected during boot, it gets disabled by the driver. Not sure what to do if the internal LCD goes bad.?
The USB ports are USB ver 1.1 and very slow. The front one does not supply much current. The rear will power an external HD.
I tried to clone the drive two different ways. Both failed...
First was to insert the 40GB into a another PC. The BIOS kept reporting an issue with the drive so I gave up. I have cloned many drives this way without issue.?
Second I used a USB-IDE with a 60GB drive connected to the PNA. Loaded Acronis Enterprise onto the PNA. Unfortunately Acronis didn't force a reboot after configuring it so the cloning never happened. I gave up before I corrupted the drive.?
Still looking for a safe way to clone the drive. With only a USB 1.1 port, the cloning will take forever....

Peter,
If you could look under the front panel and take a photo of the same
area that would be fantastic. I believe the B upgrade kit was
supposed to delete that because the battery type changed and was
moved to one of the new digital logic boards that was part of the
A->B upgrade.

Re: Replacement battery for 8566A
I'm pretty sure it's not there. I hope it's not too much of a hassle
to read those EPROMs. I think there are very few of these units out
there with that firmware.

Hi Peter
This is digging *way* back in the cobwebs of my mind... CIIL stands
for "Control Intermediate Interface Language", which was part of "MATE",
which was a DoD (Department of Defense) initiative for automated test
back in the '80's meant to standardize programming of instruments.
There was special firmware developed as an option for this in some of
the HP instruments of the time. I never got very involved with it
because at the time I didn't have any DoD customers. It was never very
popular, and shortly died out. (this was also around the time that IEEE
488.2 was introduced and pretty much did what DoD was trying to do with
MATE/CIIL.
Maybe some others here may have a better recollection.

So it turns out I was thinking of another analyzer, perhaps one I
fixed for a friend. My unit started out as a B, the screen says on
startup:
HP-IB ADRS: 18
8566B-E69 <CIIL> (C) 14.6.85
I'm not sure what the E69 or <CIIL> mean or if I have the most up to
date firmware but the analyzer works just fine so far as I can tell.

Re: HP5335A rough calibration
Here are the final results of the calibration. I ran the configuration described previously for 24 hours. As indicated in my last message, after 10 hours the display showed 10,000,000.01. Over the next 14 hours it varied between 9,999,999.99 and 10,000,000.01. I measured the drift between the GPSDO and MV89A signals at different times during the last 14 hours with the following results: 1) 3 am - the MV89A lost 1/2 cycle every 1 minutes, 8 seconds (this represents a frequency difference of .007 Hz); 2) at 7 am it lost 1/2 cycle every 2 minutes (This represents a frequency difference of .004 Hz); at 4 pm it lost 1/2 cycle every 1 minute 27 seconds (this represents a frequency difference of .006 Hz). I should mention that at the stated times, I would make the frequency drift measurement, then nudge the frequency adjust voltage to change the drift to the slowest I could make it.
Once again, thanks to all who commented. I very much appreciate the help given.
Regards,
Dan

The best solution is to go with nicads as originally designed.?

I talked to the fellow I bought the system from and he may have a battery holder assembly, so I'm going to wait to see if I can get one before bodging anything in.

Re: E8357A upgrade questions
I have a drive clone device (stand alone ) that worked perfectly on the e8357a and e8358a hd's that Caesar graciously?gave me over the years.? ?I will dig up thename and model and post it when I fine it in tbe basement.?
Thank you again Caesar.?
Pete wa2odo
As a follow up, Caesar helped me updated my PNA to the 500MHz CPU and 40GB HD. The machine runs way better and I can keep a USB hub (Keyboard and mouse) connected full time. The original 266MHz CPU was sluggish and wouldn't boot if a USB hub was connected. I tried multiple hubs to no avail.
Drive Ceasar supplied has XP SP2. Not sure if SP3 will work or provides any improvement.?
It took me a while to get the floppy to work. It seems it only likes floppies formatted by it and it may have had dust inside.?
You can use an external VGA monitor if you use the display driver utility to enable it. If the external monitor is disconnected during boot, it gets disabled by the driver. Not sure what to do if the internal LCD goes bad.?
The USB ports are USB ver 1.1 and very slow. The front one does not supply much current. The rear will power an external HD.
I tried to clone the drive two different ways. Both failed...
First was to insert the 40GB into a another PC. The BIOS kept reporting an issue with the drive so I gave up. I have cloned many drives this way without issue.?
Second I used a USB-IDE with a 60GB drive connected to the PNA. Loaded Acronis Enterprise onto the PNA. Unfortunately Acronis didn't force a reboot after configuring it so the cloning never happened. I gave up before I corrupted the drive.?
Still looking for a safe way to clone the drive. With only a USB 1.1 port, the cloning will take forever....
