Hello all!
I have a simple question (for you but not for me) related with a polarity relay controlled by GPIB.
The situation is as follows: We want to do a measurement with DC bias scanning from positive to negative voltage (loop measurement). Currently, we can apply DC input voltage (on either fixed polarity) to DUT, and then acquire measured data (say, output voltage from DUT), controlled by GPIB/LabView.
We have an Agilent digital DC power supply (E3641A), which has a typical one-pair port output. What we want to have is, to scan both polarity, a switch/relay which can flip between POS and NEG controlled by GPIB (with manual switch, preferable). The basic method is very simple but we have no idea on detail switch product.
Is such switch/relay avaialble as a product? And any detail information? OR is there any other smart way we can switch the polarity??
Thank you so much for your suggestions.
