R&S ESU
6.16.1 SENSe:AVERage Subsystem
The SENSe:AVERage subsystem calculates the average of the acquired data. A new test result is
obtained from several successive measurements.
There are two types of average calculation: logarithmic and linear. In case of logarithmic average calcu-
lation (denoted with VIDeo), the average value of the measured logarithmic power is calculated and in
case of linear average calculation, the linear power is averaged before the logarithm is applied.
The measurement windows are selected by SENSe1 (screen A) and SENSe2 (screen B).
[SENSe<1|2>:]AVERage:COUNt 0 to 32767
In receiver mode, this command defines the number of scan started with single scan. In analyzer
mode, it defines the number of measurements which contribute to the average value.
It should be noted that continuous averaging will be performed after the indicated number has been
reached in continuous-sweep mode.
In single sweep or scan mode, the scan/sweep is stopped as soon as the indicated number of
measurements (scans/sweeps) is reached. Synchronization to the end of the indicated number of
measurements is only possible in single scan/sweep mode.
The command [SENSe<1|2>:]AVERage:COUNt is the same as command [SENSe<1|2>:
]SWEep:COUNt. In both cases, the number of measurements is defined whether the average
calculation is active or not.
The number of measurements is valid for all traces in the indicated measurement window.
Example:
"INIT:CONT OFF"
'Switching to single-sweep mode.
"AVER:COUN 16"
'Sets the number of measurements to 16.
"AVER:STAT ON"
'Switches on the calculation of average.
"INIT;*WAI"
'Starts the measurement and waits for the end of the 16 sweeps.
Characteristics: *RST value: 0
SCPI: conform
Mode: R, A
[SENSe<1|2>:]AVERage[:STATe<1...3>] ON | OFF
This command switches on or off the average calculation for the selected trace (STATe<1...3>) in the
selected measurement window.
Example:
"AVER OFF"
'Switches off the average calculation for trace 1 in screen A.
"SENS2:AVER:STAT3 ON"
'Switches on the average calculation for trace 3 in screen B.
Characteristics: *RST value: OFF
SCPI: conform
Mode: R, A
