Trigger Output (TRIGGER OUT)

Do not short the TRIGGER OUT terminal or apply external voltage to it. Doing so may damage
the instrument.
French
Ne pas court-circuiter la borne TRIGGER OUT et ne pas appliquer de tension de sortie. Cela
pourrait endommager l'instrument.

The following CMOS level signals can be transmitted.
Trigger Output (Normal)
When the output format is set to normal, the terminal transmits a falling signal when a trigger
occurs. The signal level is normally high but goes low when a trigger occurs.
Trigger Output (Pulse)
When the output format is set to pulse, the terminal transmits a pulse signal when a trigger occurs.
You can set the pulse width.
Sample Clock Synchronization Signal Output (Sample Pulse)
When the output format is set to sample pulse, the terminal transmits a pulse signal at regular
intervals when waveform acquisition is started. You can set the pulse rate.
Start/Stop Level Signal Output (Start/Stop)
When the output format is set to start/stop, the terminal transmits start/stop level signals. The signal
level is high during waveform acquisition and goes low when waveform acquisition is complete.

CMOS level (0 to 5 V)
Logic Low when a trigger occurs and high after acquisition is completed
Output delay Within 100 ns + 1 sample period
Output hold time 100 ns or more
Logic Transmits a pulse when a trigger occurs
Output delay Within 100 ns + 1 sample period
Pulse width 1 ms, 50 ms, 100 ms, or 500 ms
Transmits pulses at a given frequency during waveform acquisition
Pulse rate 5 Hz to 200 kHz (1-2-5 steps)
However, the interval must be longer than the DL850E/DL850EV
sampling interval. The interval can be set to 1 over the integer
multiple of the DL850E/DL850EV sampling interval.
Logic High level output during waveform acquisition
Low level output while waveform acquisition is stopped
