Auto-calibration and auto-zeroing
Auto-calibrate the U2020 X-Series without having to connect it to a power
reference, or auto-zero the U2020 X-Series with or without the RF/microwave
signal present.
Zeroing is recommended:
– when connection to the U2020 X-Series is established.
– every 24 hours.
– prior to measuring low-level signals.
The U2020 X-Series will perform auto-zeroing and auto-calibration every time it is
powered up.
