R&S FSMR SENSe:AVERage - Subsystem
1313.9723.12 6.1-149 E-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
calculation (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
This command 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 mode, the sweep is stopped as soon as the indicated number of measurements
(sweeps) is reached. Synchronization to the end of the indicated number of measurements is only
possible in single 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: "
SWE: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: conforming
[SENSe<1|2>:]AVERage[:STATe<1 to 3>] ON | OFF
This command switches on or off the average calculation for the selected trace (STATe<1 to 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: conforming
[SENSe<1|2>:]AVERage:TYPE VIDeo | LINear
This command selects the type of average function. If VIDeo is selected, the logarithmic power is
averaged and, if LINear is selected, the power values are averaged before they are converted to
logarithmic values.
The type of average calculation is equally set for all traces in one measurement window.
Example: "
AVER:TYPE LIN"
'Switches screen A to linear average calculation.
Characteristics: * RST value: VIDeo
