AC POWER INPUT. A three-pronged recessed mate connector
is provided on the back panel for AC power connection to
the instrument. Also contained in this assembly is a
1/2A slow blow fuse and a removable card that can be
removed and repositioned to switch between 120V AC in
and 240V AC in.
2.0A SB. This fuse protects the output stage if the
output duty cycle rating is exceeded.
AMP. To voltage control the output amplitude, set the
switch in the EXT position and apply Oto +10 Volts
between terminal A and_= ground (Rrin>10K). The front
panel controls are still active in this mode.
PW. The putse generator may be triggered externally in
a PWourt = PWrn mode by setting the switch in the EXT
position and applying a TTL level pulse of the desired
pulse width to the A connector.
BCT Option. The -BCT option provides a rear panel BNC
output connector which provides a double pulse output
(TTL Tevels). The pulses are 200 ns_ wide and the
separation between the leading edges is variable from 1
us to 10 ms via a_ four position range switch and a_ one
turn control. The leading edge of the first pulse is
coincident with the leading edge of the main output
pulse. The double pulse output is provided when the
unit is triggered externally in the PWrn = PWout mode
(and also when triggered internally).
