5 - 34 FUNCTION REFERENCE
EXTERNAL TRIGGER (2 CHANNELS MODELS ONLY)
Description:
The External Trigger input provides an extra input that can be used as the trigger
source for the Main Time Base (MTB).
The External Trigger input chargacteristics are simular to those of the input
channels 1 and 2. The input has probe range indication detection and two
attenuator positions (0.1 V/div. and 1 V/div.). If External is selected as trigger
source the same trigger modes (Edge, TV and Glitch) are availlable as for the
trigger sources CH1 and CH2.
When the External Trigger input is selected as trigger source , the signal on this
input can be made visible by pressing the function key TRIG VIEW. When another
Trigger source is selected, Trigger View is automatically switched off.
Trigger View can be used in Single- and Multiple shot in timebases up to 10µs/div.
In the other timebase modes Trigger View automatically selects Alternating mode
for timebases faster than 10µs/div. This result in the simultaneous acquisition of
the External Trigger input.

Key to turn on and off the display of the external trigger
signal.
