Re: Readings from 436A power meter using 82357B USB-GPIB?


 

Hello,

Thanks for the suggestion. I have tried this, but it doesn't seem?to work. Any recommendations to how I should configure Interactive IO? I will use Visual Basic in Excel for later programming - hopefully using Agilent VISA libraries...
?
In general, anyone with experience of communicating over USB-GPIB 82357 with _very_ old instruments (single character commands etc...)? Is there a fundamental limitation?

Is there any way of performing low level communication/control of the 82357, i.e., controlling the separate digital lines?

Regards,
? Staffan?

Hi Staffan

Yes, you need to meter to be in addressable mode (or as you say, "normal").
If you use the interactive IO, you would use the "Send and Read"..? Type the command to fetch the reading in the text box, and use the "Send and Read" button, which will set the computer as the talker, send the command, and then it sets it up so the meter is the talker.? You should see the results show up in the history below.? It puts the actual results there, with no additional formatting so you can see exactly what it sends back.? Of course you can also do it individually using the separate "Send Command" and "Read Response" as well. The "Send and Read" just combines the two actions.
What language do you plan to use for your program?

Hello,

Just got hold of an old HP436A power meter and would like to do some automated measurements. Controlling the instrument is simple using the 82357B USB-GPIB module (I can set range etc), but reading data? As a first step I'd like to test using Agilent Interactive IO from Connection Expert. If that works, I'm fairly sure I can get it working in a program also.?
The 436 is set to NORMAL, i.e., not TALK ONLY. It does have the HP-IB option 022 installed. My guess is that I need to address the instrument to Talk in some other way than the "Read Response" used in Interactive IO.

Anyone with experience of this?
