8.3 Other Functions
・ Oscillation mode
Oscillation mode CONT, BRST, TRIG, GATE
CONT : Continuous oscillation.
BRST : Repeats oscillation of the mark wave number, and stop of
the space wave number.
TRIG : Performs oscillation of the mark wave number by the trigger
signal
G AT E : Performs oscillation while the gate signal is valid.
Mark wave number Number of oscillation cycle for Burst and Trigger oscillation mode.
0.5 to 128.0 : 0.5 increments
1 to 256 : 1.0 increments (Both mark and space wave numbers
need to be integers)
Space wave number Number of stop cycle for Burst oscillation mode.
0.5 to 128.0 : 0.5 increments
1 to 256 : 1.0 increments (Both mark and space wave numbers
need to be integers)
Phase Oscillation start/stop phase for Burst, Trigger, and Gate oscillation mode
Setting range ±180.0°
Setting resolution 0.1° Resolution
Trigger source Logical sum of the triggers by external trigger input, panel key and
remote interface
External tr igger input
Trigger polarity Rise/Fall for tr igger oscillation mode (selectable)
High level/Low level for gate oscillation mode (selectable)
Input level TTL level
Impedance Pull-up to +3.3 V at 100 kΩ
