[SENSe<Sensor>:]AVERage[:STATe] <state>
Available in continuous average mode.
Enables or disables the averaging filter.
Parameters:
<state> *RST: ON
Manual operation: See "<Mode>" on page 50
9.8.2 Setting the Frequency
The frequency of the signal to be measured is not automatically determined. For ach-
ieving better accuracy, the carrier frequency of the applied signal must be set.
[SENSe<Sensor>:]FREQuency <frequency>
Transfers the carrier frequency of the RF signal to be measured. This frequency is
used for the frequency-response correction of the measurement result.
The center frequency is set for broadband signals, e.g. spread-spectrum signals, multi-
carrier signals.
Parameters:
<frequency> Range: 0.0 to 110.0e9
*RST: 50.0e6
Default unit: Frequency
Example:
FREQ 10000
Manual operation: See "Frequency" on page 45
9.8.3 Configuring Corrections
It is possible to set some parameters that compensate for a change of the measured
signal due to fixed external influences.

9.8.3.1 Duty Cycle Corrections
The duty cycle is the percentage of one period during which the signal is active, when
pulse-modulated signals are corrected. The duty cycle is only evaluated in the Continu-
ous Average mode.
