Hi David

Could you help me regarding the Receiver Personality DLP

?

Have you ever used the Receiver Personality program if so what are the major advantages ?

?

You refer to the ?firmware revision 94120 [B.05.00].``is this for the local oscillator ?70900 or the 71910 analyser ?

?

You also say it was on a memory card and a disk ?how much memory dues it require and can it be copied from a local oscillator ?70900 and loaded onto another

?

Sorry for all the questions but I think many are after the answers to the questions that I have asked

?

Regards Paul

Are you asking about the Receiver Personality DLP (Downloadable Program) for the?HP 71910A wide-bandwidth receiver?

?

More information on this DLP can be found here:

?

?

Specifically, the details on how to install it can be found on page 1-31 of the second document.

?

There is a memory card version, and a LIF disk version, which requires connecting a HP 9122 drive.

?

This personality requires?firmware revision 94120 [B.05.00].``

OK on the posting but please explain the software you require

Is it to enhance the operation of the 70910A ?

Or is it to run on a computer system

or is it to up grade the ?local oscillator that has the software to run the 70910? providing the revision is late enough? to run your other components

Sure ¡ª injection molded parts are great, but the quality of those feet, when 3D-printed out of something strong like polycarbonate on a reasonably priced printer (~$750 range) would be entirely satisfactory. The layers can be thin and the exterior can be printed slowly to make it look just about perfect.

Discounting printer amortization, the consumables for a set of 4 of those feet would be a few dollars at most. You can get a lot of feet from 1kg of material...

Re: HP 6012B volt zero and current regulation

 

I made a constant current load at work, 100 amps 200 volts, of course with a control loop.? When first connected the loop is calling for max current and it made a big current spike.? As this was annoying (making cables jump), I changed it to have a slow start ramp, taking a second to ramp up.? That was pretty easy so I imagine it shouldn't be a problem making a voltage mode supply do the same, and I would expect any decent one to behave that way.

All that was said about control loops is true, you can't get out of that, it's all about the loop bandwidth and also every regulated supply has a particular response, which may be critically, under or over damped.? I have absolutely seen supplies ring in response to a transient load change.? I have also seen really really bad power supply behavior like a 40 volt 20 amp Harrison HP bench supply go severely overvoltage - completely wide open - when a noisy load was applied.? I literally GAVE that supply away.
