Horizontal Sync Rate Shift
System parameter settings
801GC, 801GC-ISA, 801GF, 801GF-ISA and 801GX only
Temporarily shifts the horizontal sync frequency of the generator. The first parameter
controls the amount of shift (in Hz) and the second parameter controls the approximate
length of time (in seconds) that the frequency is shifted, before returning to nominal. Both
parameters can be entered as floating point numbers.
HSRS shift_factor shift_period
shift_factor
should not exceed ±10% of normal horizontal rate to ensure stable operation of the
generator
shift_period
non-negative
HSRS -100 2.5 // Shifts the horizontal rate of the currently running
// format down by 100 Hz for about 2.5 sec.
