SENSe<ch>[:POWer]:TYPE?
The command queries the type of sensor. The type is automatically detected.
Return values:
<Type>
Example:
Usage:
Manual operation:
:SENSe<ch>[:POWer]:ZERO
The command activates the autozero function. Zeroing is required in regular interval (at
least once a day) and if the temperature has varied more than about 5 °C, if the sensor
has been replaced or if measurements of signals with very low power are to be per-
formed. The RF power source must be switched off or disconnected from the sensor
before starting the autozero function.
Example:
Usage:
Manual operation:
:SENSe<ch>:UNIT[:POWer] <Power>
