Description
instrHandle
ViSession
The Instrument Handle is used to identify the unique
session or communication channel between the driver
and the instrument. If more than one instrument of the
model type is used, this will be used to differentiate
between them. Note that the initialize function may be
used to associate multiple instrument handles with a
single instrument.
stdSampleClockFrequency
ViReal64
Returns the present setting of the sample clock
frequency. Note that this parameter is not programmable
and is automatically set by the
3156B for the appropriate
standard waveform
frequency, depending on the number
of points the
3156B defines for generating the standard
waveform shape.
Return Values
Displays the return status of the function call. If the function was successful, it will return a status of
VI_SUCCESS, otherwise it will return an error code. Passing the error code into the function
"ri3156B_error_message()" will return a string describing the error.
