P2: phase value #2
SPACE T PSK rate
TRIG Trigger source for PSK
Trigger source “TRIG”
Select internal signal and external input signal 1: INT or 2: EXT. The default of the instrument is
internal. In internal mode, the phase of the output signal shifts according to the PSK rate parameter.
In external trigger mode, the trigger signal is applied to the Ext. Trig” Input terminal on the rear
panel. In external trigger mode, the trigger signal applied to the trigger input terminal on the rear
panel determines the PSK rate. Logical “high” of the trigger signal is associated with phase value #2,
while the “Low” level of the trigger signal is associated with phase value #1.
Phase 1 “P1”
The first start phase value of the PSK output signal.
Input range of phase 1 and phase 2 is º0.0º~ 360.0º.
Phase 2 “P2”
The second start phase value of the PSK output signal.
Input range of phase 1 and phase 2 is 0.0º~ 360.0º.
Spacing time “SPACE T”
PSK rate: Range is 0.1ms ~ 800s.
