The sensor returns the result in the unit set with command
Certain power sensors, such as the R&S NRP-Z81, return two
values, first the value of the average level and - separated by a
comma - the peak value.
Example:
SENS1:UNIT DBM
// Selects unit dBm for presentation of measurement result
READ1?
// Queries the measurement result of the sensor
// -45.6246576745440230
// -45.6 dBm were measured at the given frequency
Example:
R&S NRP-Z81
READ1?
