Power Meter Remote Operation
1
Some fine tuning of measurements can be carried out using the CONFigure
command and INITiate and FETCh? commands. For example, in the above
program segment some fine tuning can be carried out by setting the filter length
to 1024 and the trigger delay off.

2 CONF1 -50,DEF,(@2)
3 SENS2:AVER:COUN 1024
4 TRIG2:DEL:AUTO OFF

Example 4 - Specifying the Resolution Parameter
The previous examples detailed the use of the expected value and source list
parameters. The resolution parameter is used to set the resolution of the specified
window. This parameter does not affect the resolution of the data, however it does
affect the auto averaging setting (refer to
Figure 1-2
on page 85).
Since the filter length used for a channel with auto-averaging enabled is
dependent on the window resolution setting, a conflict arises when a given
channel is set up in both windows and the resolution settings are different. In this
case, the higher resolution setting is used to determine the filter length.
The following example uses the resolution parameter to specify a resolution
setting of 3. This setting represents 3 significant digits if the measurement suffix is
W or %, and 0.01 dB if the suffix is dB or dBm (for further details on the resolution
parameter refer to the commands in
Chapter 2, "MEASurement
Commands").
Also, in this example the expected power and source list parameters are
defaulted. The expected power value is left unchanged at its current setting. The
source list parameter is defaulted as described in the note
"Keysight N8262A"
on
page 65. Note that as the source list parameter is the last specified parameter you
do not have to specify DEF.
