Power Meter Remote Operation
Making Measurements
1-20 HP E4418B/E4419B Programming Guide
Using the CONFigure Command
When you execute this command, the power meter presets the best
settings for the requested configuration (like the MEASure? query).
However, the measurement is not automatically started and you can
change measurement parameters before making measurements. This
allows you to incrementally change the power meter’s configuration from
the preset conditions. The power meter offers a variety of low-level
commands in the SENSe, CALCulate, and TRIGger subsystems. For
example, if you want to change the averaging use the
[SENSe[1]]|SENSe2:AVERage:COUNt command.
Use the INITiate or READ? query to initiate the measurement.
Using READ?
CONFigure does not take the measurement. One method of obtaining a
result is to use the READ? query. The READ? query takes the measurement
using the parameters set by the CONFigure command then sends the
reading to the output buffer. Using the READ? query will obtain new data.
Using INITiate and FETCh?
CONFigure does not take the measurement. One method of obtaining the
result is to use the INITiate and FETCh? commands. The INITiate
command causes the measurement to be taken. The FETCh? query
retrieves a reading when the measurement is complete, and sends the
reading to the output buffer. FETCh? can be used to display the
measurement results in a number of different formats (for example, A/B
and B/A) without taking fresh data for each measurement.
CONFigure Examples
The following program segments show how to use the READ? command
and the INITiate and FETCh? commands with CONFigure to make
measurements.
It is advisable to read through these examples in order as they become
increasingly more detailed.
These examples give an overview of the CONFigure command. For further
information on the CONFigure commands refer to Chapter 2,
“MEASurement Instructions”.
