DiffChan (Differential Channel)

Specifies the differential channel on which to make the first measurement. If the Reps parameter is greater than 1, additional measurements will be made on sequential channels.

If the DiffChan number is entered as a negative value, all Reps are performed on the same channel (burst measurement). The CR300 burst measurement sampling rate is determined by the f_N1 (first notch frequency) parameter.

fN1 (Hz)	Burst Sampling Rate
50 or 60	50 mSec (or 20  samples per second)
400	6.25 mSec (or 160 samples per second)
4000	0.5 mSec (or 2000 samples per second)

Type: Constant
