Agilent 6050A, CC mode trying set current protection

[ewtotem]

I am communicating with my 6050A DC Load through GPIB.  Everthing seems to set fine, accept the Current protection mode does not seem to enable (PROT indicator does not come on).  The value is set to be +3 higher than the current value set.  I expect to only use this feature for transient states (obviously, its in CC mode), but it will not even turn on.  There are no errors Labview or Instrument.  the concept seems to work fine on the Agilent N3300A.

See attachment for a look at the vi

Hello ewtotem:

Have you tried experimenting with the settings? If so, do you ever get any different results? Do you know the command to turn on current protection (PROT) on your device?

[ewtotem]

Hi Roland,

Yes I have tried experimenting with the settings. No I do not get any different results.  The command to enable the device is located within the settup VI.  You can see this with my first attachment.  Please take a look at the 2nd example.

Hello ewtotem:

Looking into the first VI, I went into the block diagram of HP 6050A/51A Config.Current.VI and I see the path it takes to enable current protection. I do not immediately see something wrong with the code, but I will check into it more. Have you been able to produce another other results?

Hi Roland,

I haven't been able to make it change.  Apparently, the PROT indicator is suppose to come on, according to Agilent, but he wasn't a Labview guy. I am building another test station, I will see if the same thing happens with that setup and let you know.

Mr Roland,

I have an Agilent 6050A and Agilent 60502B. I am trying to run it using Labview 8, via IEEE488.

Do you have the set of drivers and the Labview Library to run them ?

Do you have a multipurpose VI to use it. This is my application:

          1) I have a variable source to test with Agilent 6050A / Agilent 60502B

          2) I want to change the sink current (I) of Agilent 6050A and

          3) Measure the apparent voltage (V)

          4) then draw an I-V curve.

If you the drivers and VIs, please post them, so that I can dwnload them and use them.

Or give me the procedure how to get them

I have a very urgent need for these VIs (students are waiting to use the machine).

Thank you very much.

Happy thanksgiving

Go to the Instrument Driver Network and do a search. With LabVIEW 8.x, you can also perform the search from the menu Tools>Instrumentation>Find Instrument Drivers.
