The major inputs and outputs of the instrument are available at the front
panel:
The external input (EXT INPUT) can be used to connect an external
arming source (started or gated modes). For details, please refer to
The Mode/Trigger Screen on page 60
.
The trigger signal (TRIGGER OUT) marks the start of the pulse
period or of parts of a pattern (see
The Mode/Trigger Screen on
page 60
). You can set the output levels according to the used
technology (TTL, ECL, PECL) or enter test-specific values (see
The
Trigger-Level Screen on page 96
).
The strobe signal (STROBE OUT) marks beginning and end of a burst
in Burst mode. In Pattern mode, this signal is programmable per bit.
The OUTPUT connectors provide the signal output (normal and
inverted), the indicators show the current state of the output (on or
off).
