1 ms to 10000.000 s (during 2 channel independent, sweep or
modulation of only one of the channels)
2 ms to 10000.00 s (other times)
1 ms
Indicates start of single / gated sweep.
100 ms and more (If applying less than 100 ms, trigger is at 100
ms intervals).
Selectable internal trigger oscillator or external trigger input.
Also, applicable from panel keys and via remote control (GPIB or
USB)
The CH1 external trigger can also be selected for the CH2 trigger
source.
Selectable rise/fall.

1 µs to 100.0 s
4 digits at 1 ms and more, 1 µs at less than 1 ms.
On/off setting effective during gated sweep.
(However, ineffective and fixed at off if the sweep item is duty)
Off: stop at set phase.
On: stop at set stop level.
