Fluke PM-3370B SENSeAVERageCOUNt SENSeAVERageTYPE?, Response Scal, Initiates trace averaging

COMMAND REFERENCE 4 - 77

SENSe:AVERage:COUNt

SENSe:AVERage:TYPE?

Syntax: SENSe:AVERage:COUNt <NRf>

<NRf> 2 4 8 16 ... 2048 4096

SENSe:AVERage:TYPE?

Response: SCAL

Query form: SENSe:AVERage:COUNt? [MINinum MAXimum]

Response: 2 4 8 16 ... 2048 4096

If MINimum was specified, 2 is returned.

If MAXimum was specified, 4096 is returned.

Description:

The SENS:AVER:COUN command sets the preprocessing average count factor. The count factor is a multiple of 2. The average value is calculated by the oscilloscope as follows:

AVGn = ∑(X1 + ... + Xn ) ⁄ n

The SENS:AVER:TYPE? query returns the preprocessing average type used, which is the SCALar implementation.

If the oscilloscope is in the analog mode, error -221 "Settings conflict; Digital mode required" is generated.

After a *RST command, the average count factor is 8.

Example:
Send → *RST	Resets the instrument.
Send → CONFigure:AC	Configures for AC-RMS.
Send → SENSe:AVERage:COUNt 16	Average count factor becomes 16.
Send → SENSe:AVERage ON	Switches average function on.
Send → INITiate	Initiates trace averaging.
Send → *WAI	Waits for INITiate to finish.
Send → TRACe? CH1	Queries channel 1 trace.

Read ← <channel 1 trace averaged over 16 sequential acquisitions>

Front panel compliance:

The SENSe:AVERage:COUNt command is the remote equivalent of the front panel AVERAGE count option of the ACQUIRE menu.
