example, you cannot change the filter length. To make more flexible and accurate
measurements, use the CONFigure command. MEASure? is a compound command
which is equivalent to an ABORt, followed by a CONFigure and a READ?
MEASure? examples
The following examples describe how to use the MEASure? query to make a
measurement. These examples configure the U8480 Series for a measurement (as
described in each individual example), automatically place the U8480 Series in
the “wait-for-trigger” state, trigger the U8480 Series to take one reading, and
then send the reading to the output buffer.
For further information on the
MEASure? query, refer to the “Measurement
Commands” on page 72.
Example 1 - The simplest method
The following shows the simplest method of making measurements using MEAS?
Example 2 - Specifying the source list parameter
The MEASure? query has three optional parameters: an expected power value, a
resolution, and a source list. These parameters must be entered in the specified
order. Parameters may be defaulted from the right by omitting them, or anywhere
by substituting the keyword DEFault. The parameter DEFault is used as a
placeholder.
The source list parameter is used to specify a measurement channel. The U8480
Series supports only one channel. Therefore, the only valid value is (@1). The
expected power and resolution parameters are set to their default values, leaving
them at their current settings.
