Setting range of space wave number 0.5 cycles to 999,999.5 cycles, in 0.5-cycle units
Oscillation stop unit during gate 1 cycle, 0.5 cycles (selectable)
Oscillation start/stop phase setting range
−1800.000° to +1800.000° (0.001° resolution)
Remark: Same setting value as phase setting in section
7.3
Stop level setting range
Function Specification of signal level when oscillation is stopped
Setting range −100.00% to +100.00% of amplitude full scale (0.01%
resolution) or off
When the stop level is set to off, stop occurs at the set
