Re: Hp 8590a eeprom problem.

Richard Cook
 

Yes I cleaned the contact points with alcohol and q tip, for the female receptacle part I used a acid brush and alcohol.??
Well guess what, it worked good, put the cover back on and my friendly fail code 1310 appears again. How aggravating. It indicates eeprom u21. I got the part number off the IC PMI 8639 1826-1048. I'm not sure how to read the chip I see a lot of chip with 1826-1048 but not the first number 8639. Can someone enlighten me on this.?
Thanks?


Re: 8341B vs 8673B

 

Matt -
AFIK, the source modules are not connected to the 8430 in the same way they are connected to the 8350 (and also, I believe to the 8673).

I'm just starting to play with the source modules (HP series) and will let you know. I believe I will need to use the 8510 multiplier technique.

Cheers!

I believe it's under System -> More -> EDIT MULT. SRC.

Take a look at Controlling Multiple Sources in the 8510C operating
manual. Forward a few pages there's a section entitled "SOURCE 1 Formula
Use". This allows you to apply offsets and multiplications to a source.

If you have the official HP/Agilent mm source modules, these should have
a bus that does this for you; i.e., you don't need to mess with these
menus.

If you don't have the official modules, then this would indeed be the
approach.

Sure - I just never thought about it that way - I was thinking that the 8340 would be where the configuration was done.

No problem

I should clarify this statement as it's somewhat poorly phrased. The
8510C doesn't apply frequency offsets or multiply your RF source
signal. It simply tells the RF source to generate a frequency that is
some combination of offset and multiple or submultiple of the displayed
frequency for a given sweep point. Probably obvious, but worth
clarifying. This is all explained in the manual.

Even using 8340B stand alone the reading is the multiplied frequency.

If i have to go lower than 26 GHz i connect direct the 8340B to the 8515

thats all.
That's a cool capability I wasn't aware of. Thanks for pointing that out
Gianni. It would be nice if the 8510 could control a switch driver
controlling a pair of switches too. That way, you could get the full 10
MHz to 52 GHz in one sweep. That would be useful for things like time
domain low pass mode. I didn't see anything about that in the manual
though.

Hi Gianni,

Can you elaborate on this 8510C setup a bit more? The 8340 through the
x4 Marki goes to an 8517? Does the 8510C software handle this fine? Do
you just restrict the 8510 frequency range to the quadrupler input range
and then just adjust the display readings in your head? Or, does the
setup work a little differently?

Thanks
Matt

Re: Suffering from RIFA anxiety!

 

Filters on power cord entries are as much to protect the
instrument from RFI as to protect the power line from RFI.

HP has used such filters, well, just about forever.

Re: Suffering from RIFA anxiety!

 

Hi Dave,

I was, and I wasn't.

The Schaffner filters are reported to contain the yellow
epoxy covered RIFA brand capacitors in their internal
filters... They would seemingly have to be some sort
of safety cap because they come before the fuses.

I have seen RIFA caps that were used in other ways that
were bad, though I have not seen one blow up.

It might be time to blow a few just for the experience.

All I can say is in 4 decades of designing, using,

a Schaffner filter blow up. Tomorrow may be the day

The goodness of the whole idea of putting several
safety caps, which are designed to blow without
catching the instrument on fire, in a can full of tar
eludes me.

Mostly the failure rate of RIFA paper dielectric safety

In other words, for older capacitors:
If you use a 250VAC RIFA cap on 240VAC mains, failure is
all but assured.

If you use a 250VAC RIFA cap on 120V mains, you will likely
never see a failure.
That's nowhere near true in the field, unfortunately. I've
replaced two 250VAC RIFA capacitors run on 120V in the past week
alone. These blow up *all the time*.

Storage in a humid environment dramatically accelerates the
failure of RIFAs.

Or so says my 40 years of experience as an engineer, with never
seeing a single RIFA capacitor failure on 120VAC.
You've been lucky.
