Using The Lower Level Commands - Agilent Technologies EPM-P Series Programming Manual

Using the Lower Level Commands

An alternative method of making measurements is to use the lower level
commands to set up the expected range and resolution. This can be done
using the following commands:
[SENSe[1]]|SENSe2:POWER:AC:RANGe
DISPlay[:WINDow[1|2]]:RESolution
The measurement type can be set using the following commands in the
CALCulate subsystem:
CALCulate[1|2]:MATH[:EXPRession]
CALCulate[1|2]:RELative[:MAGNitude]
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 1-1 on page 1-8 the CONFigure command presets various
states in the power meter. It may be likely that you do not want to preset
these states.
Example
The following example sets the expected power value to -50 dBm and the
resolution setting to 3 using the lower level commands. The measurement
is a single channel A measurement carried out on the lower window.

CALC2:MATH:EXPR "(SENS1)"
SENS1:POW:AC:RANG 0
DISP:WIND2:RES 3
