Burst, gate, trigger and trig’d gate
(Trig’d gate: gate on/off at each trigger)
0.5 to 500000.0, 0.5 cycles
(The mark wave number is the oscillation wave number at the
time of burst and trigger).
0.5 to 500000.0, 0.5 cycles
(Space wave number is the stop wave number at the time of
burst).
Phase from oscillation stop to oscillation start
−1800.000° to +1800.000°
0.001°
Selectable internal trigger oscillator or external trigger input.
Trigger can be applied from the panel keys or via remote control
(GPIB or USB).
The external trigger of CH1 can also be selected as the CH2
trigger source.
Trigger: Rising or falling edge selectable
Gate: Positive or negative logic selectable.
Trig’d gate: Rising or falling edge selectable
High level ≥ +3.9 V, low level ≤ +1.6 V
50 ns
At 10 kΩ, pull up to +5 V.
Front panel BNC receptacle (TRIG/SWEEP IN)
1µs to 100.0 s
4 digits at 1 ms and more, 1 µs at less than 1 ms.
0.3 µs to 100.00 s
5 digits at 1 ms and more, 0.1 µs at less than 1 ms.
Oscillation mode: Effective with trigger.
Less than 50 ns
On and off settable
Off: stops at set phase.
On: stops at set stop level.
