HORizontal:MAIn:INTERPRatio?
Description
This query--only command returns the Horizontal Main time base inter-
polation ratio. The ratio is useful for calculating the maximum sampling
rate when users request sampling rates that are faster than the maximum
rate specified by the acquisition hardware.
The query HORizontal:MAIn:SAMPLERate? returns the sampling rate
(real and interpolated). The real maximum sampling rate, as specified
by the acquisition hardware, is:
Max sampling rate =
HORizontal:MAIn;SAMPLERate?/HORizontal:MAIn:INTERPRatio?
The default value is 1.
An interpolation ratio other than 1 means that displayed and retrieved
waveforms contain additional points that are derived through interpola-
tion. At such times, the retrieved waveform data is actually 16--bit data.
You should set the data width accordingly.
