MEASure Group of Commands

This measures the total rms power in a specified integration bandwidth. You must be in the Basic, cdmaOne, cdma2000, W-CDMA (3GPP), or W-CDMA (Trial & Arib) mode to use these commands. Use INSTrument:SELect to set the mode.

The general functionality of CONFigure, FETCh, MEASure, and READ are described at the beginning of this section. See the SENSe:CHPower commands for more measurement related commands.

Measurement Results Available

n	Results Returned

0	Returns unprocessed I/Q trace data, as a series of comma-separated trace
	points, in volts. The I values are listed first in each pair, using the 0
	through even-indexed values. The Q values are the odd-indexed values.

not specified or n=1	Returns 2 comma-separated scalar results:
	1. Channel Power is a floating point number representing the total
	channel power in the specified integration bandwidth.
	2. PSD (Power Spectral Density) is the power (in dBm/Hz) in the
	specified integration bandwidth.

2	Returns comma-separated floating point numbers that are the captured
	trace data of the power (in dBm/resolution BW) of the signal. The
	frequency span of the captured trace data is specified by the Span key.
