4 Measurement Operations & Settings
Response: The last data acquisition function's data array as a binary block.
One measurement value is a 4 byte little-endian IEEE 754 single precision value.
For Logging and Stability Data Acquisition functions.
For the MinMax Data Acquisition function, the query returns the minimum, maximum and current power values.
See Data Types for more information on Binary Blocks.
See How to Log Results for information on logging using VISA calls. There are some tips about how to use float format
specifiers to convert the binary blocks (32 Bit / IEEE 754 single precision format).
Example: :sens1:func:res? → #255.....
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
Command: :SENSe[n]:FUNCtion:RESult:BLOCk?
Syntax: :SENSe[n]:FUNCtion:RESult:BLOCk?<wsp><offset>,<# of data points>
Description: Returns a specific binary block (Intel byte order) from the data array for the last data acquisition function.
Parameters: <offset> A zero based offset; the number of data points to ignore.
# data points The number of data points (not bytes!) to return.
Response: The last stablility or logging data acquisition function's data array as a binary block.
This function is not available for min-max measurements.
One measurement value is a 4 byte little-endian IEEE 754 single precision value.
Example: :sens1:func:res:bloc? #5, 2 → interpreted as 7.24079E-04,7.24252E-04
Affects All power meters
Command: :SENSe[n]:FUNCtion:RESult:BUFA?
Syntax: :SENSe[n]:FUNCtion:RESult:BUFA?
Description: Returns the data array of the last data acquisition function in Buffer A.
This works only for Logging and Stability Data Acquisition in the loop mode, not for the MinMax Data Acquisition.
For details look at description and example in :Using data buffers for simultaneous measurement and upload"
Parameters: None
