8.4.2 Selecting a Measurement Path
The RANGe subsystem contains commands for selection of a measurement path.
Remote commands:
[SENSe<Sensor>:]RANGe
[SENSe<Sensor>:]RANGe:AUTO
[SENSe<Sensor>:]RANGe:CLEVel
[SENSe<Sensor>:]RANGe <range>
Selects the active measurement path manually.
Parameters:
<range>
[SENSe<Sensor>:]RANGe:AUTO <state>
Enables automatic measurement path selection.
Parameters:
<state>
[SENSe<Sensor>:]RANGe:CLEVel <level>
Reduces the transition range between the measurement paths, 0 -> 1 and 1 -> 2, by
the set value. Thus, you can improve the measurement accuracy for signals with a
high peak-to-average ratio, since the headroom for modulation peaks becomes larger.
However, the S/N ratio is reduced at the lower limits of the transition ranges.
Parameters:
<level>
8.4.3 Selecting a Measurement Mode
► Before starting a measurement, select the measurement mode using:
[SENSe<Sensor>:]FUNCtion
The following modes are available:
●
Continuous average ("POWer:AVG"): After a trigger event, the power is integrated
over a time interval.

The sensitivity of the paths differs.
0 is the most sensitive path.
2 is the most insensitive path.
1 is the path with medium sensitivity.
