How to set the point interval in Tektronix TDS220?

[yjiang]

I am programming a program by LabVIEW which read and control a Tektronix TDS 220 through serial port. When I need to specify the data points into steps of 6.25E-5(s), I used the command "WFMPre:XINcr 6.25E-5" as the programmer manual points out. But the sampling interval still keeping as it was, not changed. I want to know which command can specify the interval in time domain? Thanks!
