Fig. 2-30 Signal example 2: double pulse, TRIGGER MODE = EXT, SLOPE = POS
Note: The minimum period length depends on parameters WIDTH and PULSE DELAY. To avoid a
settings conflict the following has to be true:
PERIOD
≥
1,1 × (WIDTH + PULSE DELAY) + 30 ns
For double pulse the following has to be true:
DOUBLE PULSE DELAY
≥
WIDTH + 40 ns
Menu MODULATION-PULSE offers access to settings for pulse modulation and to the pulse generator.
If only option SM-B3, pulse modulator, is fitted, only the first 3 lines are displayed in the setting menu.
