[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.
● Duty Cycle Corrections ........................................................................................... 94
● Offset Corrections ................................................................................................... 95
● S-Parameter Correction .......................................................................................... 96
● S-Gamma Corrections ............................................................................................ 98
● Using the S-Parameters Tool ................................................................................ 100
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.
