1) TRIG
The instrument starts one measurement only after receiving one trigger signal.
There are four trigger modes: INT (internal, EXT (external), MAN (manual), BUS. The
instrument only receives trigger signal at current trigger mode.
Internal:
When the trigger mode is set to INTernal trigger mode, the instrument
continuously repeats measurements.
External:
When the trigger mode is set to EXTernal, the instrument performs a single
measurement every time a low-to-high transition TTL level signal is applied to
the Handler interface on the rear panel.
BUS:
When the trigger mode is set to BUS trigger mode, the instrument performs a
single measurement every time the *TRG common command is sent to TX7410
via GPIB. The BUS trigger mode cannot be set on the front panel. Send the
TRIGger:SOURce BUS command via GPIB or RS232C to set the trigger mode to
the BUS trigger mode.
Manual:
When the trigger mode is set to MANual trigger mode, the instrument performs
a single measurement every time when TRIGGER key on the front panel is
pressed.
Perform the following steps to change trigger mode:
