for hp33120a IVI driver,how to change high impedance?

[tunmin]

I am going to use hp33120A to generate a waveform. I also need to control the impedance of it become High impedance.

Are you using the LabVIEW instrument driver? If not, go to http://ni.com/idnet/, and search for "33120a". I downloaded the LabVIEW Plug and Play driver--i.e., the native LV source code driver. (There are also CVI and IVI drivers available.)

Anyway, if you download this driver, the VI you want is called "ag33xxx - Config Outp Term.vi".

I hope this helps.
