Description
Set or query the channel source of waveform data reading.
Parameter
Name Type Range Default
<source> Discrete {CHANnel1|CHANnel2|MATH|FFT|LA} CHANnel1
Explanation
The following two methods can be used to set FFT as the channel source for waveform data reading.
Set <source> to FFT
Set the operation source of MATH to FFT and then set <source> to MATH.
When LA is set as the channel source of waveform data reading, the return format is WORD; namely,
each 2 bytes represent a group of digital signal states and each bit represents a single digital signal
channel. The highest bit represents D0 and the lowest bits represents D15.
Return Format
The query returns CHAN1, CHAN2, MATH, FFT or LA.
