The generator front panel controls and connectors are
shown in figure 3-1 and keyed to the following descriptions.
G)
POWER Switch
Turns generator on and off.
Frequency Dial
Settings under the dial index mark multiplied by
@
determine the output signal frequency. The
dial calibration marks correspond to the frequency
(black) numbers only. The period (grey) numbers
are approximations only. Refer to table 3-1 for
quick period/frequency conversion. The frequency
can be varied by the vernier

OPERATION
GENERATOR MODE Switch
Selects one of the following three modes.
CONT - Continuous output at FUNCTION OUT,
SYNC OUT and, if PULSE WIDTH is on, PULSE
OUT connectors.
TRIG - DC level output at all six output connec-
tors until the generator is triggered by MANUAL
TRIGGER switch or with a signal at the TRIG IN
con nectar. When triggered, the generator output is
one cycle of waveform or one pulse period followed
by a de level.
GATE - As for TRIG except the output is contin-
uous for the duration of the trigger signal at TRIG
IN. The last cycle or period started is completed.
