HP-53132A Faded and flickering display
Dear Group,
Good morning! I just got my first HP-53132A frequency counter and Prologix GPIB-USB converter. Now I can do some measurements and I am excited about it. Everything looks promising. Condition of the instrument on the outside is like new, controls responsive and no fading in lettering at the buttons. Connectors are not worn or damaged, original connectors. The unit has been tested and works OK, probably not with adequate calibration but that is not an issue now, I can always calibrate it later.
What worries me is the display. Even though being an Agilent built unit, it has probably more hours on it than a seldom used HP built unit. The flourescent display is fading, not all the digits show consistent illumination levels. The left-most digits show some flickering at some of their segments. It is readable in the end, but I am terribly disappointed about it.
Does anybody know if there is a cure for this? Or should I start saving for a better unit.
I am not afraid of the screwdriver or the soldering iron if someones suggests a display overhaul. Thank you!
Regards,
Edgardo Molina

You will be using the counter much on the GPIB than looking to the display,
so try to keep the unit untouched. Better to use it and think about another
one, now that you have one, you are not in a hurry so you can select a
better one. You can also hunt for an SR620 or a Wavecrest... 25pS (or less)
instead of 150pS is better. Isn't it?

The replacement display board is available for about $550. The display itself may be available if you could find the part number for about $125, but Agilent WILL NOT give the raw display part number out. I ran into this same problem with the 3458A and was finally able to find the number and order some. Does anyone on the list have the raw display part number? There is also a small chance the problem is in the HV module. Perhaps going straight to the display vendor.

Edgardo,
Two possibilities: Cathode poisoning or bad tantalum caps. I'm not sure if "cathode poisoning" is really the correct term for this effect, but it's similar. There have been a number of tutorials out there about rejuvenating VF displays.
The one I have direct experience with is bad caps. We bought an HP 6612C power supply with a bad display for an automated test setup. It's basically the same VF display used in a lot of the instruments from that family.
We didn't really need the display because it was for an automated setup, but I wanted to fix it anyway. When I removed the display board I found that it had 3 or 4 large tantalum caps on one edge. One of the caps was toasted a crispy brown color instead of the usual yellow. After replacing that cap the display came right back to life and has been working fine for a couple of years, now.
BTW: those display and button boards are a bit of a trick to remove. They're slide in from the side under some "L" shaped plastic features in the case front. There are instructions in the service manual for dealing with them.
-John

Dear Azelio,
Thank you. You are right regarding the GPIB operation but since I was looking for a high resolution frequency counter as well for a versatile basic instrument to start measuring with, I choose this frequency counter.
Hunting for a better unit right now will not be a priority as the budget is tight and I can always have one for Christmas without being audited by my significant other ; ) Still, it would be very nice to go down to 25ps for sure!
Thank you for your feedback. Have a great day.

Unless it is a bad tantalum capacitor, as suggested: in this case yes, it
has to be fixed.

Should the display prove to be beyond recovery it might be possible to buy a new one. Now, the cost may be another matter ...
These are made by Noritake-Itron. The generic part number is CP3033A, but it does not show up in their product line on their web site. It might be worth contacting them to see if there's any possibility of still getting them.

Hi all,
to avoid more display "consumption" during long acquisitions, there is
an HPIB command to blank the display on the counter. I have asked to
KE5FX to add this feature in Timelab during the acquisition setup. Hope
he have time to do this.

Dear Azelio, Tom, John and Luciano ( I hope I am not missing anybody),
Thank you all of you for your kind advise on this subject. I am sorry I was unable to reply in a timely manner. I had to leave town for a week for new IT business. I think I will start by dismantling the unit display and test the tantalum capacitors as you mentioned. If I can achieve success by doing this it is fine. Otherwise I could consider using it as the GPIB workhorse as I just started to obtain my first ADEV, MDEV and TDEV graphs with TimeLab and a Prologix adapter. May I know the command for turning the display off via the GPIB port? That is something nice for long periods of sampling.
A whole new world has just opened to me. Know I am starting to get intimate with my frequency standards by knowing them in deep. If all goes well I should start updating my wish list for a Wavecrest DTS unit next year. For now I will squeeze every single Tau value from the graphs using the 53132A.
Last but not least. If the display fades away I could eventually consider buying a new one as the whole instrument is in pristine condition and would be a shame to see it working without a brilliant display.
Thank you for all your feedback.
Wishing you all a pleasant evening/morning.
Kind regards,
Edgardo Molina

Hi Edgardo;
I have been looking for a part number and source. There was a part number posted but it was for the 34401A which is slightly different. I will post price and availability if I find them.

These are made by Noritake-Itron. The generic part number is
CP3033A, but it does not show up in their product line on their web

possibility of still getting them.

Subject: Re: [time-nuts] HP-53132A Faded and flickering display
Dear Azelio, Tom, John and Luciano ( I hope I am not missing anybody),
Thank you all of you for your kind advise on this subject. I am sorry I was unable to reply in a timely manner. I had to leave town for a week for new IT business. I think I will start by dismantling the unit display and test the tantalum capacitors as you mentioned. If I can achieve success by doing this it is fine. Otherwise I could consider using it as the GPIB workhorse as I just started to obtain my first ADEV, MDEV and TDEV graphs with TimeLab and a Prologix adapter. May I know the command for turning the display off via the GPIB port? That is something nice for long periods of sampling.
A whole new world has just opened to me. Know I am starting to get intimate with my frequency standards by knowing them in deep. If all goes well I should start updating my wish list for a Wavecrest DTS unit next year. For now I will squeeze every single Tau value from the graphs using the 53132A.
Last but not least. If the display fades away I could eventually consider buying a new one as the whole instrument is in pristine condition and would be a shame to see it working without a brilliant display.
Thank you for all your feedback.
Wishing you all a pleasant evening/morning.
Kind regards,
Edgardo Molina

Hi all,
to avoid more display "consumption" during long acquisitions, there is an HPIB command to blank the display on the counter. I have asked to KE5FX to add this feature in Timelab during the acquisition setup. Hope he have time to do this.

Hi Edgardo,all,
the command to blank the display you can find:
http://cp.literature.agilent.com/litweb/pdf/53131-90044.pdf
page 3-36
Disable display:
:DISPlay:ENABle OFF (See Note below.)
Note: This value is not stored on Save and is not part of the
non-volatile state.
Hope this command will be implemented in Timelab soon.

It seems like you need to do what I did, go to the agilent site and
download the manuals. Operations and Programming manuals is easy, there
is then a service manual and component-level manual.
The programming manual should assist you on turning of the screen.
The component level manual does not detail the power-supplies.
Did anyone here analyse the analogue interpolators of the 53131/53132?
It's a relative simple design being used with a single transistor and
charging a cap and then read from an ADC. The ADC reference voltages can
be calibrated from a DAC. Notice that there exists two versions of the
main board, for each of the models and that they have different
schematics set in the same manual.
Cheers,
Magnus
Hi
If you go shopping for a parts donor, a 53181 is probably going to be much cheaper. Most of the parts that burn out are common between the models.

Hi Edgardo,
I bought my used hp-53132A from a local surplus dealer together with a
new spare display, because the display was as well already grey-shaded.
It looks like this is a well known issue on vaccuum fluorescence
displays, because the previous owner was prepared and had some spares in
their stock.
The spare display is manufactured by the japanese company 'itron' and
has the item no. 'CC1187G' on the backside.
I was very lucky to get both together for a reasonable amount.
It does look to be problem now to find such spares, the only company I
found having that part number listed in internet is chip-sale dot com.
(this does not look to be cheap ...)
I was not able to find this number at http://www.noritake-itron.com.
Sorry that I do not have better information, perhaps other groop members
do find a way with this part number.
good luck,
Arnold
Thanks Arnold the more information on this issue the better. I will take a look at your links.

The HP manual I have lists DS29 as CP3033A 0950-2327 on the schematic
sheet and PC assembly list as Samsung INB-12MM53T with Agilent P/N
5040-0023.
That should add to the search list of replacements.
