:SENSe[n][:CHANnel[m]]:FUNCtion:PARameter:STABility?
:SENSe[n][:CHANnel[m]]:FUNCtion:PARameter:STABility?
Returns the total time, period time, and averaging time for the stability data acquisition
function.
none
Total time, delay time, and averaging time are float values in seconds.
sens1:func:par:stab?
+1.00000000E-001,+1.00000000E-001<END>
All power meters and return loss modules
Can only be sent to master channel, slave channel parameters are identical.
:SENSe[n][:CHANnel[m]]:FUNCtion:RESult?
:SENSe[n][:CHANnel[m]]:FUNCtion:RESult?
Returns the data array of the last data acquisition function.
none
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 23 for more information on Binary Blocks.
See "How to Log Results" on page 150 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 values.
If you use LabView or HP VEE, we recommend using the Agilent 816x VXIplug&play Instru-
ment Driver to perform the Logging and Stability Data Acquisition functions.
