Hi Joel,
Thank you for your help!
I only have the oscilloscope with single-ended inputs and would like to use this oscilloscope to measure the differential outputs of ADRF6510. For differential measurements, I use two channels of the oscilloscope and invert one channel. Then adding both channels is to obtain the differential outputs of ADRF6510. Is it correct? I also need to switch the impedance of two channels to 1M Ohm when I measure differential signals.
Our DAQ is NI USB 6009. The input impedance of DAQ is 144K Ohm, higher than 400 Ohm. But the common-mode is guaranteed around 2.5 V. Do you think it is OK to connect ADRF6510 with this DAQ?
Thanks.
