Making Measurements
The MEASure? and CONFigure commands provide the most
straight-forward method to program the power meter for measurements.
You can select the measurement’s expected power level, resolution and
with the HP E4419B the measurement type (that is single channel,
difference or ratio measurements) all in one command. The power meter
automatically presets other measurement parameters to default values as
shown in Table 1-3.
Table 1-3: MEASure? and CONFigure Preset States
An alternative method to program the power meter is to use the lower
level commands. The advantage of using the lower level commands over
the CONFigure command is that they give you more precise control of the
power meter. As shown in Table 1-3 the CONFigure command presets
various states in the power meter. It may be likely that you do not want to
preset these states. Refer to “Using the Lower Level Commands”, on
page 1-29 for further information.
