Measurement Operations & Settings Measurement Functions – The SENSe Subsystem
94 Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition
command:
:SENSe[n][:CHANnel[m]]:FUNCtion:PARameter:LOGGing
syntax: :SENSe[n][:CHANnel[m]]:FUNCtion:PARameter:LOGGing<wsp><data points>,
<averaging time>[NS|US|MS|S]
description: Sets the number of data points and the averaging time for the logging data acquisition func-
tion.
parameters: Data Points:
Averaging time:
Data Points is the number of samples that are recorded before the log-
ging mode is completed. Data Points is an integer value.
Averaging time is a time value in seconds.
There is no time delay between averaging time periods. Use
“:SENSe[n][:CHANnel[m]]:FUNCtion:PARameter:STABility?” on
page 97 if you want to use delayed measurement.
If you specify no units for the averaging time value in your command, seconds are used as
the default.
NOTE
See “:SENSe[n][:CHANnel[m]]:FUNCtion:STATe” on page 100 for information on start-
ing/stopping a data acquisition function.
NOTE
See “:SENSe[n][:CHANnel[m]]:FUNCtion:RESult?” on page 97 for information on accessing
the results of a data acquisition function.
NOTE
See “Triggering and Power Measurements” on page 171 for information on how triggering
affects data acquisition functions.
response: none
example: sens1:func:par:logg 64,1ms
affects: All power meters and return loss modules
dual sensors: Can only be sent to master channel, slave channel is also affected.

command:
:SENSe[n][:CHANnel[m]]:FUNCtion:PARameter:LOGGing?
syntax: :SENSe[n][:CHANnel[m]]:FUNCtion:PARameter:LOGGing?
description: Returns the number of data points and the averaging time for the logging data acquisition
function.
parameters: none
response: Returns the number of data points as an integer value and the averaging time, t
avg
, as a float
value in seconds.
example: sens1:func:par:logg? → +64,+1.00000000E-001<END>
affects: All power meters and return loss modules
dual sensors: Can only be sent to master channel, slave channel parameters are identical.
