8.4.2 Selecting a Measurement Path
The
RANGe
subsystem contains commands for selection of a measurement path.
Remote commands:
[SENSe<Sensor>:]RANGe
................................................................................................48
[SENSe<Sensor>:]RANGe:AUTO
......................................................................................48
[SENSe<Sensor>:]RANGe:CLEVel
.................................................................................... 48
[SENSe<Sensor>:]RANGe <range>
Selects the active measurement path manually.
Parameters:
<range> 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.
Range:
0 to 2
*RST: 2
[SENSe<Sensor>:]RANGe:AUTO <state>
Enables automatic measurement path selection.
Parameters:
<state> *RST: ON
[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> Range: -20.00 to 0.00
*RST: 0.00
Default unit: dB
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.
