Improve the calibration procedure for different setups


I have to perform a measurement with different settings (power, bandwidth, ...).

If I use the microwave prober with an on-chip calibration substrate to perform a TOSM calibration, it would take a very long time because I have to reconnect all four standards for every setup.

Is there a way to improve this?


You can use a segmented sweep.

Define one sweep segment for each setup. The frequency ranges of the sweep segments can overlap up to 100 %.

When you calibrate the whole segmented sweep, all setups will be calibrated in one sweep. You only have to connect the four calibration standards once.

If you want to measure the sweep segments (setups) separately, you can copy the channel as often as you want and switch off all sweep segments in the channel except the one you want to measure.
