Using MEASure?

The simplest way to program the power meter for measurements is by
using the MEASure? query. However, this command does not offer much
flexibility. When you execute the command, the power meter selects the
best settings for the requested configuration and immediately performs the
measurement. You cannot change any settings (other than the expected
power value, resolution and with the N1912A the measurement type)
before the measurement is taken. This means you cannot fine tune the
measurement, for example, you cannot change the filter length. To make
more flexible and accurate measurements use the CONFIGure command.
The measurement results are sent to the output buffer. MEASure? is a
compound command which is equivalent to an ABORT, followed by a
CONFigure, followed by a READ?.
MEASure? Examples
The following commands show a few examples of how to use the
MEASure? query to make a measurement. It is advisable to read through
these examples in order as they become increasingly more detailed. These
examples configure the power meter for a measurement (as described in
each individual example), automatically place the power meter in the
"wait- for- trigger" state, internally trigger the power meter to take one
reading, and then sends the reading to the output buffer.
These examples give an overview of the MEASure? query. For further
information on the MEASure? commands refer to the section
"MEASure[1]|2|3|4 Commands"
Example 1 - The Simplest Method
The following commands show the simplest method of making single
channel (for example A or B) measurements. Using MEAS1? results in an
upper window measurement, and MEAS2? in a lower window measurement.
The channel associated with the window can be set using the source list
parameter (see

on page 147.
