SENSe Subsystem

Sets the instrument state parameters so that you can measure the input signal.

The SCPI default for data output format is ASCII. The format can be changed to binary with FORMat:DATA which transports faster over the bus.

Adjacent Channel Power Measurement

Commands for querying the adjacent channel power measurement results and for setting to the default values are found in the “MEASure Group of Commands” on page 255. The equivalent front panel keys for the parameters described in the following commands, are found under the Meas Setup key, after the ACP or ACPR measurement has been selected from the MEASURE key menu.

Adjacent Channel Power—Average Count

[:SENSe]:ACP:AVERage:COUNt <integer>

[:SENSe]:ACP:AVERage:COUNt?

Set the number of data acquisitions that will be platform averaged. After the specified number of average counts, the average mode (termination control) setting determines the average action.
