About the interface cards
Averaging
(Specification according to „1999 SCPI Command reference“:4 Calculate Subsystem)
CALCulate
:AVERage:COUNt?
:AVERage:COUNt
:AVERage:AUTO
:AVERage:STATe
Examples:
CALC:AVER:COUN8
If actual values are queried with MEAS:, the average value of the last 8 measurements is returned
CALC:AVER:STATOFF
Stops averaging, only the last measured values is delivered.
Attention! This setting is not saved. It is reset to its default value 100 after a restart of the device.
The averaging performs x measurements of all actual values within a certain interval and these measurements are used to
form the average value. It can be queried with the MEAS: command, after the measuring cycle is finished.
If averaging has been turned on by CALC:AVER:STAT ON, a measurement cycle is started by *TRG (at setting CALC:
AVER:AUTO ONCE), which measures depending on CALC:AVER:COUNT x times before the OPC bit in the status Event
Status Register ESR is set. This is signalising, if enabled, the state via the esr bit in the status register STB. The status
register STB automatically generates a service request call.
Only after this, the measured values are allowed to be read. In case they‘re read too early, the interface will return ERR
-00, Execution error.
If averaging has been turned on with CALC:AVER:STAT ON and CALC:AVER:AUTO ON was set, the measurement cycle
does auto-repeat. The measured values and the device status are recorded every 0ms, so that at the default setting of 10
measurements the OPC is set every 000ms. The measured values can be read out, after bit OPC has been queried.
Attention! When using averaging, it is required to query the bit OPC before the measured values are read out with
MEAS. Else an error is returned.

-><1..100>
Queries the number of measurements used for averaging
<1..100>
Set the number of measurements for an averaged actual value
(Default is 100, *RST has no effect)
B
Using „ONCE“, only one measurement will be performed
Using „ON“ repeats the measurement automatically
The measurements always are for U
*RST cancels the averaging
B0
„ON“ starts, „OFF“ stops averaging
