Keysight 81150A - Arming Source

Appendix
94
3.1.1 Arming Source
Introduction
The following sources are available:
 External In
 Internal
 Man
External In
This input allows to define the decision in a 10 V for 81150A (5 V for
81160A) voltage window. The input signal is referenced to chassis ground.
81150A: The input impedance may be set to either 50  or 10 k.
81160A: The input impedance may be set to either 50  or 1 k.
Internal
Each channel of the Keysight 81150A / 81160A contains it’s own internal
trigger event generator. The frequency of the trigger event may be adjusted
as required for the specific application.
The Internal trigger generator cannot be used to generate the gate signal.
Man
The Man key on the front panel may be used to generate the trigger event or
gate signal manually. When receiving the *TRG command, the instrument
will emulate a press and release event of the Man key.
