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 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.
ABOR1 Aborts Channel A
CALC2:MATH:EXPR
"(SENS1)"
Displays Channel A on lower window
SENS1:POW:AC:RANGE 0 Sets lower range (E-Series sensors and N8480
Series sensors (excluding Option CFT) only)
DISP:WIND2:RES 3 Sets the lower window’s resolution to setting 3
INIT1 Causes Channel A to make a measurement
FETC2? Retrieves the lower window’s measurement
