Re: BRIGHT Replacement LCD for 8753/8720 VNAs with dim LCD displays
Hello Ed,
I would like to have information about the keyboard and display you
have used with the 8753D. Thanks.
Steve, K8JQ

Another option with
the HP8753D is to use an external display, a fairly common PC
display.
I have used one for
several years, and an external keyboard as well.? Both are
easily available
as PC
items, older and inexpensive.? The PC keyboard takes most of
the work out of labeling
the display
so the printed display is much better for your record keeping.
Back to the
PC video display.? Look at your 8753D manual and note the
frequency of the sweep.
It is lower
than the spec's of many video displays so match this when you
choose one.? Also check
which of
the three colors carries the sync signal.? That is critical.
Naturally
you have to match the connectors for all external
accessories.? Connect everything and look
at the
display.? It probably it needs the Horizontal width adjusted.?
Display a Smith Chart and adjust
the width
until it is round.? Easy!
I can go
check which display and keyboard I am using if there is any
interest in this addition.?

The 16700 files (DISK1.DAT, INDEX.TXT, INFO.TXT) need to be copied to
a floppy and then you need to do a software installation from the
files on the floppy.
This is an example of what you can see in a listing window using the FuturePlus config and IA tools with an E2423A SCSI Bus Preprocessor on a 16700 series logic analyzer. I truncated most of the columns from the listing window and the output is probably still too wide to display correctly in email.

Re: Weinschel step attenuator gets stuck
Hello Tom, I also have a HP8593E - a little over a year now.? I really like it.? About a month after purchase it went blind - backup battery died.? I'm just glad it was not a blown front end.? Anyway I had to re-accomplish the leveling calibration points - over 100 points.? In retrospect, when I first got it , I should have gone through the procedure that records all these points then it just would have been a matter of reentering them from a hard-copy record.?

Hi Ian,
many thanks for the warm welcome. Now it's over with being incognito ;-)
I'm trying to get into the high GHz field using high notch second hand HP equipment.
Here's my complete HP inventory for the records:
HP425A (excellent uV meter with valves, that I could rescue from junk and fix it successfully)
HP3430A (DVM, also rescued from junk, nice, but a bit bulky, not used lately)
HP34401A (impressive 6.5 digit multimeter, purchased recently)
HP8350B+HP83529A (cool sweeper 10MHz...20GHz, purchased recently. I'm using it a lot. Quite instructive to see how various coax cables behave at 18GHz.)
HP8593E (my latest purchase, 26.5GHz SA to replace a borrowed HP8591A).
I might need advice on the HP8593E soon when I have time to take care. I have the impression that the highest band (19GHz...26GHz) shows 10dB to low amplitudes, verified with the sweeper as signal source up to 20.4GHz and double-checked against a Gigatronics power meter, which nicely matches the HP83529A output power display within a few tenths of a dB). The noise floor of that band displays 5dB lower that that of the previous band. I would have expected it to be 5dB higher than that of the previous band as harmonic mixing gets increasingly less efficient at higher harmonics. I wonder if this can be fixed with a software setting.
Best regards,

Joe, drop me a private post. If you can wait 3+ weeks until I can access my lab. Ill look to see if I have any AVANTEK GPDs of the correct spec. Ill send you one free if I do....Im really not certain if I have any of them left.

Wanted: spare internal 10 dB pad for HP 8562A A9 input attenuator
Anyone knows how to get?at decent price?a working order 22 or 26.5 GHz 10 dB glass replacement pad (so-called "Attenuation Card"), that's found in the 70 dB A9 input step attenuator of my 8562A SA? Several part numbers, electrically matching A9 may be found: 5086-7371 5086-7783 5086-5783 5086-7796 5086-7822 5086-7842 8340-60175 8673-60043 8673-60044 33321-60038 33321-60039 33321-60057 33321-60058 33321-60061 33321-60080 83595-60019 85660-60301 HP8495K HP 33321D/K/RF/RG/RU/RV/T HP 33323K N4413-80004
| So I'm just looking for that 10 dB pad, not necessarily a $100-300+ complete assembly. |
Please note: 18 GHz 10 dB pads mechanically don't fit.

Re: Weinschel step attenuator gets stuck
Hi Rastro,
many thanks for the very informative links! From what I can tell, the Weinschel attenuators are mechanically absolutely identical with the HP ones, either one builts in license from the other or all come from the same source.

Hi Gary,
I had a similar problem with a HP5335A counter. What I did was to design a circuit board and place 10 series resistors on it, each 15 ohm, 0.25 W. These resistors were placed in series with the DC fan. I mounted the board inside the unit on the right side with four screws. Perfect, nice and quiet.

Re: OT Rod terminating resistor
Yes, I asking for 3 samples and few days later was contacted by guy from France, company representing them for Europe. Typical story, what's project, annual prevision....and at end he come with small quantity "sample" price of about 25USD for BeO and 20USD for Alumina substrate!
BTW, I have very good experience with many other companies regarding the free samples of semiconductors, IC's and optoelectronics.

Hi Gary,
What I do is remove the front panel from the instrument, and set
it on a pan to catch the drippings. Then I take a little pump
sprayer, like is used for windex, and liberally hose down the
entire switch area with IPA. While I do this, I push the buttons
multiple times to get the IPA under the springs, and wash out the
remnants of the grease. I then hose it down a couple of times more
with more IPA.
After that is done, I let the panel drip, for a few minutes, and
then blow the IPA off gently with compressed air. The more IPA
you can remove mechanically, the cleaner the springs and switches
will be.
After blowing the IPA off, put the panel in a warm place, and let
the remaining IPA evaporate, and you are back in business.

thread running where I and others have posted their solutions - I just
did a
3456A and 3455A as well as an 8566A and other gear - but this is what I
did:
Remove the switch PCB from the panel, flood spray the switches with IPA
(Isoprop
alcohol) and operate each a few times, within just three or four
operations they
free up like magic going from clunky
'feels-like-something-is-about-to-bust' to
almost silky smooth! Then blow it off with an air-gun and give it another
dose
for luck. Works for me anyway!

Thanks, that would be great to have the?E2423A?files online.? That's a bit of sad news that they don't work with 16700.? Though it justifies keeping a 16500 around.
