1.3.8 Externally Triggered PM Envelope
(one envelope produced by each trigger supplied)
Repetition Rate: 5 Hz to 5 MHz
Pulse Delay: Set by internal delay control.
Pulse Width: Set by internal width control.
Input Trigger Required: Positive or negative-going TTL level trigger pulse, >25 ns wide.
1.3.9 Externally Generated PM Envelope
(one envelope produced by each pulse supplied)
Repetition Rate: 5 Hz to 5 MHz, leveled output;
DC to 10 MHz, unleveled output.
Pulse Delay (output envelope
leading edge referenced to
input pulse leading edge): 50 ns, typical
Input Pulse Required: Positive or negative-going TTL level pulse,
>50 ns wide (leveled output);
>20 ns wide (unleveled output).
