What is the Openchoice call monitor used for with the Tektronic TDS20002C Oscilloscope?
The software used to control the Tektroniks RDS20002C oscilloscope is TekVISA. The application is available for a multitude of devices released by Tektroniks. I advise going to the official website to find additional information about it. However, I see that this device doesn't appear on the list of supported devices which means you will either need another version or another software. Use the Support zone to get additional information for this device (account required!).
