Does anyone still deals with HP3048A Phase Noise Measurement System?

[danielmechanics]

Hello,
I am currently on a project dealing with phase noise measurement. The instrument available is HP3048A(Phase Noise Measurement System)

However, I have this problem that is to extract the program codes used to control various equipment: HP11848A (Phase Noise Interface), HP3561A(Dynamic Signal Analyzer)using LabView 6.1 because I do not have the program codes to control them. The interface used: GPIB
I have the program used by HP3048A to control the instrument but the language is BASIC and the codes used does not seems to work well in Labview 6.1

For example: "RST" when input via using HP3048A can preset the instrument 3561A but does not work for LabView6.1

Can anyone out there help me?
Regards,
Daniel

Hello,

You can open the LabVIEW GPIB shipping example (See Help -> Find Examples...) this will allow you to write RST to the instrument (or anything else for that matter)and read any response.

This should get you started! The only piece of information you need to know is the address (primary and secondary if necessary) of your instrument.

Best Regards; repost if you still have questions!

Thank You very much for your response JLS

I am using VISA to write the command "RST" to 3561A to preset the instrument however, no response from the instrument.

But when I used HP3048A, BASIC programming language to write a "RST" string command to 3561A, the instrument did responded by presetting. Thus this set me wondering what has gone wrong.....

I to have the 3048 system, it is frustrating that it is written in basic. I had to write some code and if I remember right you have to put a delimiter behind the RST. I think it is a ";". Try that.

Hello,

Using VISA while specifying your GPIB resource, you should be writing whatever string you send, and your instrument should receive it. This should be completely independent of the language used. I know that *RST is a rather common command, and semicolons often delimit multiple commands sent at once. Can you try *RST and *RST; just to see if they work? Can you verify the precise command(s) in the user manual? Does any other command work using VISA?

Just a few things to try as we figure out what's going on!

Repost if you're still having trouble communicating!

Good Day,
Thanks for your reply JLS. However, the drivers that i require is not available in ident. Thus I have to source myself for the program code. If you have friends or seen anywhere in the web regarding program code for this instrument model(HP11848A) please do let me know ASAP. Thank you

Hi,

I am also dealing with the HP3048A phase noise. Does anyone have some Labview code for controlling the system? I would not like to re-invent the wheel. Any help is very much appreciated.

Hi,

Has anyone succeeded in communicating with HP3048A instrument? I am about to start on automating a setup involving HP3048A. Any help will be appreciated. Thank you.

Hello Jae,
As you know already the HP3048A consists of three instruments,
the 11848A, 3561A and A1473A, of which, only the 3561A has a LabVIEW driver.
I do not know exactly how the instruments and PC are connected to each other,
But to control the system as a whole you could use either visa or gpib to send commands
to the instruments. Have you tried using the visa or gpib communicator utilities to send
commands to the devices? If these commands are successful we can proceed to use
LabVIEW to control the system.

hello,wish to realise a bench test, order by labview.
But I have a problem, i don't  have  drivers to control spectrum analyzer whose references HP3561A. I see  on site ( national intruments ) but no drivers it offers are not good if someone could help me ...
