Subject: [HP-Agilent-Keysight-equipment] HP54610B No Display? I switched on my HP54610B scope today having not used it for a couple of years. The fan started (possibly a bit noisier and a bit slow but I¡¯m not sure), and the display remained blank, even after turning the brightness to max. It worked fine previously. I have downloaded a manual to start troubleshooting it, but before I start that I thought I would just ask if anyone is aware of any common/simple known problems that might cause this. Many thanks if you can help.

Re: 5343A equivalency to 5351B
Hello John, As Yves has said, there are no equivalent connectors on the 5351B. The 8350/83592 are quite old and the calibration procedure calls for equipment (5343A) of the same era.? The more modern 5351B does not have the connectors you are looking for. That is the reason I keep a 5343A on my bench.?

Re: Looking for HP rotary encoder datasheet/info
I can happily report that a still widely available (albeit expensive) HRPG-AD32#16F is a drop-in replacement that works perfectly, both mechanically & electrically.

I think it just dawned on me that by simply providing less detents a manufacturer can turn a "normal" rotary encoder into a pulse encoder - and so there are totally passive pulse encoders available. Is that what you were getting at ?
I would still love to see a datasheet for the QRPG-A482, however..

The device in question is a QRPG-A482, and is listed as a rotary pulse encoder. I have verified that it does indeed produce pulses, and is not a straightforward encoder.
I have spectacularly failed to find either a replacement part, or a datasheet for the device itself.
Given that these are unobtainium, I am currently planning to build a little circuit that takes a standard rotary encoder and synthesizes appropriate?pulses. Looking at the QRPG-A482 outputs, it looks like there are simply two pulses whose relative phase determines?the direction of rotation. The QRPG-A482 appears to have variable timing. I doubt very much that the timing matters and so I can likely just create pulses that look similar to the fastest ones I captured (approx 1mS wide.)
Having a datasheet for the original part might help me avoid any subtleties - even advice such as whether the outputs are likely to be open drain/collector would be appreciated.
I wonder if anyone here has travelled this path before me, and has any advice to offer. -- Andy

Looking for photos and Dimensions of U1880A Deskew Fixture
Hi all,
I have a few current probes in my collection and I'm now looking at getting a probe deskew fixture.
I want to replicate the Tek 067-1686-00, but with some 555 timers to make it self contained like the Agilent/Keysight U1880A
Does anyone here have one of these that they can scan or take good photos and measure the dimensions?
There is a photo in the user manual but it's not quite high enough resolution to see many markings (and there's no picture of the rear side)
I'll be open-sourcing my design for others to use once I have it completed.
Thanks!

Adri, Here for information, is the DANL and flatness test that I did, at the end of April 2024, after the YTF change and recalibration. When you have completed everything, you should have similar results. ? Yves ? hello Yves,
I received the 2nd converter and, after testing it on the bench (if you are interested I will give you the two test configurations) I installed it and voil¨¤, the machine is back to working like in the old days
It passes the amplitude and frequency calibrations and the confidence test without any problem
As it happened before the death of the YTO the analyzer still has a certain "deafness" after 5.5GHz
By virtue of the alignment of the spheres that I did a few weeks ago The defect is milder than it was then and I think it is due to a sub-optimal loss of insertion of the SYTF A3A2 As proof of the "deafness", while all the calibration routines, including the CAL YTF routine are performed without problems, the CAL MXR is not completed and gives the message CAL: HARMONICS INSUFFICIENT In fact I attach a screen of the 300MHz calibration signal from which it would seem that the very last harmonics are missing
Thank you in advance if can you send the analogous screen of your analyzer
In a few days I will receive a more reliable 6GHz RF generator than the current one and I will use it to try to perfect the alignment
Yves, I think that now you can reassemble and close your analyzer :-) Many thanks for all the measurements that you sent me and that were useful to trace the problem!

Hi Adri ? Here are the measurements connected to the first 2 converters as a reference. ?

It seems far from the nominal point, but there may be an error in the manual. ?

When you open your second converter, send me pictures, I'm curious. ? Yves ? dear Yves, I didn't realize that you had made the measurements expressly to help me! I owe you then a double (even triple) thanks! Especially considering the fact that the front end of this instrument is really very dense, complicated and delicate! After my last email, in addition to doing the (essentially mechanical) intervention on the SYTF, I continued to check the input signal through the various sections by alternately injecting 300MHz @-20dBm and 5GHz @0 dBm The signals were found to be in specification up to the A3A9 bandpass (where the two paths join to form the intermediate frequency of 321.4MHz). At this point I could see the 5GHz signal (converted), present at that point at -47dBm (the specification says -43/-56dBm).
Instead, no trace of the 300MHz input signal
Investigatine?the second converter A3A4 in more depth
I checked?the signals at its input
On J1 there is 3.9214GHz at -46dBm? --->OK
On J3 there is 321.4MHz @ -37.7dBm? --->OK
On J4 I did not check 600MHz @-1dBm but the fact that the converter works in band 1 tells me that the oscillator is present and is in specification
The power supply is quite OK (5V are actually 4.75; 10V are 9.98 and the DC that controls the internal switch that should be +15V? (band 0) and -3.5V?(band 1) is actually +14.60V and -1.35V
This last value is rather far from the nominal and would have worried me BUT band 1 is exactly the one that works Conclusion: it would seem that the culprit is the second converter and in particular (probably) the internal switch that has the sole task of letting the signal? (which is already at 321.4MHz and does not need to be converted)?pass from its input to the output
In the next few days I will test the converter that meanwhile?has been?disassembled?; In the meantime I found a cheap one on the bay that should arrive in about ten days

Hi Adri, ? I had sent you the measurements of the RF input-output mixer signals verification, I had disassembled the High Frequency section of my 8595E to be able to provide you with this information. If you have no more questions relating to this section, I will close my 8595E and do a flatness check to see if everything is correct. ? Yves ? ? thank you very much for all the suggestions and information with which I will continue my investigation
In the meantime I received the 2.5mm socket wrench and after?a little mod to adapt it?for the purpose (photo), I proceeded to align the spheres of the SYTF
I must say that the operation done under the microscope is quite simple
The nuts must be loosened (not too much) and with a small screwdriver that acts as a delicate lever, ?the supports of?the?spheres can be moved so that the coupling ring completely shadows them (i.e. the sphere is exactly in the center)
Removing the gold mesh was not necessary
The insertion loss has improved enormously:
at 5 GHz it is -6dBm at 6GHz it is -10dB (before the signal starting from this frequency was no longer visible) at 6.5 GHz it is only -3dB
I will install it when I have solved the problem of "blindness" in band 0 since the calibration constants that the instrument has in memory (in practice the tuning current data) are relative to the original SYTF and the "new" SYTW requires a? SYTF CAL is done

Hi, ? Good news. ? I just reassembled my 8595E, and after some checks, everything seems normal. ? I put a comparative image between our two Spectrum.

Re: 5343A equivalency to 5351B
Hi, ? I'm not sure I understand the question, but the 2 RF inputs on the front of a 5343A correspond to the two on the 5351B, as shown in the picture. ? For the INTFC signal, it is an internal synchronization signal, between the 8350B and the plug-ins. But to be able to make a measurement with a meter, you have to use the two BNC connectors 'CNTR TRIG' and 'STOP SWEEP'. The problem is that the 5351B meter does not have an INTFC B input, but the 5343A speaker does. So, if you have this meter, it would be possible to do it. ?
