Re: Agilent 8563E ERR 456 AMPL
Hi Yves,
Looks like my unit is thermal related as those ERR gone away after turn on for a while. I have it turned on for few hours now and feeding it?an FM modulated FM signal and everything sport on compare to another SA.

Re: Need urgent help with bulk TE manuals shipping problem
If NSW sorts out the COVID problem, I could be tempted to come over for a holiday and help unpack the container and catalogue. :^)

Jon Thanks, but the box problem is sorted. Today I will be buying 500 of these: ULINE, PN S-4898. 18" x 12" x 18" (Length, width, depth internal.) The container will fit 450 of them, but allowing some spares for wastage and potentially some of the manuals not fitting in the container. More details are coming together.

i have in line a system with HP8511B i intend to add dir coupler in order to perform return loss .
my goal is to become to a system like 8517 .
i have 2 Wiltron dir coupler , by now i have used 1 with a power splitter , to use the two i need the switch power splitter that is present in HP8517..
If i find this switch power splitter how to connect in in order to have the auto switch as 8517 ?
where i can find docs if the HW involved in this switch power splitter that is present inside the 8517.
Ciao IW1EPY

Re: OT: PID motor control
Dear David
I am sure that you can easily solve this without consultants. PID motor control is a classic application of control systems theory. I took the course in 1965. We used a bode plotter from ESI to find the effects ofmp?les and zeros, with special Teledeltos plotting carbon paper and an HV stylus.
The engineering application of the second order differential ¨¦quations are well documented in many papers, textbooks and courses. I highly recommend my old 1965 CCNY textbook Control System Theory by Dr Professor delToro, pub. McGraw Hill or Willey
The damping and bode plots are essential to understand how to tune a system response. Best system response is usually critical damping or slightly underdamped.
Are you simulating or have built hardware to test and tune? type and size of motor? load eg pump, fan, v¨¦hicule ?
bon courage et bon chance

204B problem in the 10k range
hello friends,
I have a little problem in my 204B Oscillator.
This apparatus have a selfmade stabilizes PSU in the back, the DC voltage is near to perfect.
Ranges? x1 / x10 / x100 / x1k? works accurate in frequeny and signal level. OK
Range x10k:
from 5 to 7 there is no oscillation. At 8 it starts, with very low output, the frequency is around 3% higher then the button scale.
In center of the button scale it work OK, but the frequency is still around 3% more then on the button.
From 20 up the signal level goes lower and lower.
So I have a problem in the 10k range parts.
How to continue ? application is here.

Re: WTB: HP 204 C or D audio Osc.
Hi Bruce,
The 204C certainly appears to be complete. ?The mounting feet are missing, but I think that is because it originally came from a field 3550 test set.
I still have the old dead batteries, but I don¡¯t see any value in shipping them to you. ?In fact it might just cause problems. ?I have included a couple of images showing the batteries.
I suggest I cut the connector based wiring harness free from the batteries and send that along.
Let me know what you think.
Thanks for your consideration.
Regards,
Ken

Hi Bruce,
I have a partially disassembled 204C.
I am certain it is missing the old batteries, but
otherwise I believe it is complete.
If you would be interested at $50.00 + shipping I will be
glad to send you a bunch of images so you can judge if it
is suitable for your needs.
Regards,
Ken

thanks for the reply,i just wondered if doing a cal with the 5.2v rail high caused this thats all.

Paul,
I¡¯ve learned that if you post something and no one responds, there is a good chance that no one has the answer to your question. I had a question about rotary encoder replacement on my HP 54645D scope probably 3 months ago and no one responded. I thought maybe I was getting ignored, but questions from other people with many answers populated my email since then. You probably just have a piece of gear that doesn¡¯t have much known information from the guys on this forum. I¡¯m not sure how to help you with your issue, but if you try the archive on the Keysight website regarding past issues there may be something hiding there. Hope that helps.?
Thanks,
