Using MEASure?
The simplest way to program the power sensor for measurements is by using
the MEASure? query. However, this command does not offer much flexibility.
When you execute the command, the power sensor selects the best settings for
the requested configuration and immediately performs the measurement. You
cannot change any settings (other than the expected power value and
resolution) 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 sensor for a measurement (as described in each individual
example), automatically place the power sensor in the “wait- for- trigger” state,
internally trigger the power sensor 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 “MEASurement
Commands” on page 66.
Example 1 - The Simplest Method
The following commands show the simplest method of making measurements.
Using MEAS1? results in the current window measurement.
Example 2 - Specifying the Source List Parameter
The MEASure command has three optional parameters, an expected power
