1 RATE switch: for selecting the ranga of the pulse rate.
2 Rate VERNIER: for continuous adjustment of the repetition
rate within the range selected on the RATE switch. Clockwise rotation
increases the pulse period (redwoq the fate).
3 PULSE DOUBLE/NORMAL switch: in the DOUBLE PULSE
position the BCtB2A delivers two pulses for every tr@ger pulse - one
pulse in pha+with the trigger owtpwt and one delayed by the amount
in the EXT WIDTH mode and is automatically inhib@d if selected.
In the NORMAL position, for each trigger pwlse, the 8DB2A delivers
one pwtse which is delayed on the trigger pulse by the amount set on
the PULSE DELAY controfs.
4 PULSE DELAY switch: for selecting the range of the pulse de-
lay with respect to the tr&er output in NORM, GATE and EXT
TRIG modes. Has no effect in the EXT WfDTH and SQUARE WAVE
5 Pulse dday VERNIER: for continuous adjustment of the pulse
delay within the range selected on the PULSE DELAY switch. Clock-
Wise rotation increases the delay.
6 EXT INPUT LEVEL control: defines the threshold
EXTERNAL INPUT over a range -1.5V to +1.5V _
7 Mode switch: selects either the internal (NORM) mode or one of
three external modes (EXT WIDTH, GATE or EXT TRIG).
8 PULSE WIDTH switch: selects the range of the pulse width re-
quired in all modes except EXT WIDTH. When SQUARE WAVE is
frequency of the square wave depends on the PULSE PERIOD setting.
9 Pulse width VERNIER: for continwows adjustment of the pulse
width within the range set on the PULSE WIDTH switch.
TRANSITION TIME switch: for selecting the range of leading
and trailing edge transition times.
LEADING EDGE vernier: for continuous adjustment of the
leading edge transition time within the range selected on the TRANSI-
TION TlNlE switch. On the fastest range this vernier controls both
leading and trailing edges.
9 2
trailing edga transition time within the range selected on the TRAN-
SITION TfME stitch.
1 3 AMPLITUDE switch: for selecting tha range of the output pulse
available at the OUTPUT / OUTPUT connactor.
ECL position the OUTPUT / OUTPUT oonnector
level of the
delivers pulses of
fixed ampfitwde (-0.9V to -1.7V into an open circuit) and the ampli-
tude vernier and the offset control are disabled.
1 4 AMPLITUDE switch: for selecti*rg range of the output pulse
amplitude available at the OUTPUT / OUTPUT connector. In the
ECL position the OUTPUT / OUTPUT connector delivers pulses of
fixed amplitude (-CL9V to -1.7V into an open circuit) and the amPh-
twde vernier and the offset control are disabled.
1 5 Amplitude VERNIER: for continuous adjustment of pulse am-
plitude from both pwlse outputs simultaneowsfy within the ranges
set on the AMPLITUDE switches.
1 6 OFFSET vernier: for adjustment of the baseline of both output
pulses simultaneously over the range -2V to *2V.
1 7 OFFSET switch: for enabling/disabling the OFFSET vernier.
In the OFF position the baseline of both outputs is zero wafts.
1 8 OUTPUT I OUTPUT connector: 8NC connector.
1 9 NORM / COMPL switch: reverses the dwty cycle of the two
outputs, what was the normal output becomes the complement and
vice versa.
21 OUTPUT / OUTPUT connector: BNC connector.
2 2 TRIGGER OUTPUT I-) connector: ENC connecto:, supplies
negative square wave at a rate determined by the setting
period controls. Pulse delay is refered to the negative going edge of
the trigger. In EXT TRIG and EXT WIDTH modes it will deliver a
shaped version of the trigger input. In GATE mode it will deliver
pulses at the rata set on the pulse period controls for as long as the
gate is open.
2 3 EXT INPUT connector: ENC connector to which trigger pulses
are epplied in the EXT TRtG, GATE and EXT WIDTH modes.
SLOPE / POLARITY switch determines whether a rising (POS)
or falling (NEG) signal will trigger or gate the external input on. MAN
position means that the external signal can be simulated by pressing
the MANUAL button.
2 5 MANUAL button provides a means of initiating a single pulse
is WJd to the time the button is pressed (EXT WIDTH mode).

2 7 LINE lamp: glows when LINE ON/OFF switch is ON.
