MEASure Group of Commands

Channel Power Measurement

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.

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.
