Measurement Functions – The SENSe Subsystem Measurement Operations & Settings
Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Fifth Edition 97
command:
:SENSe[n][:CHANnel[m]]:FUNCtion:PARameter:STABility?
syntax: :SENSe[n][:CHANnel[m]]:FUNCtion:PARameter:STABility?
description: Returns the total time, period time, and averaging time for the stability data acquisition func-
tion.
parameters: none
response: Total time, delay time, and averaging time are float values in seconds.
example: sens1:func:par:stab? → +1.00000000E+000,
+1.00000000E-001,+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.
command:
:SENSe[n][:CHANnel[m]]:FUNCtion:RESult?
syntax: :SENSe[n][:CHANnel[m]]:FUNCtion:RESult?
description: Returns the data array of the last data acquisition function.
parameters: none
response: The last data acquisition function’s data array as a binary block.
For Logging and Stability Data Acquisition functions, one measurement value is a 4-byte-
long float in Intel byte order.
For the MinMax Data Acquisition function, the query returns the minimum, maximum and
current power values.
See “Data Types” on page 26 for more information on Binary Blocks.
NOTE
See “How to Log Results” on page 207 for information on logging using VISA calls. There are
some tips about how to use float format specifiers to convert the binary blocks into float val-
ues.
NOTE
If you use LabView or Agilent VEE, we recommend using the Agilent 816x VXIplug&play In-
strument Driver to perform the Logging and Stability Data Acquisition functions.
example: sens1:func:res? →
returns a data array for Logging and Stability Data Acquisition functions
sens1:func:res? → #255
Min: 7.24079E-04, Max: 7.24252E-04,
Act: 7.24155E-04
returns the minimum, maximum and current power values for the MinMax Data
Acquisition function
affects: All power meters and return loss modules
dual sensors: Master and slave channels are independent.
NOTE
Return Loss modules:
For Logging and Stability Data Acquisition functions, the data array contains power
values.
For the MinMax Data Acquisition function, the data array contains return loss values.
