Function
or Connector
15
Output source of main generator TTL synchronization signal.
SYNC OUT (lTL)
Connector
Selects desired main generator output waveform.
16
FUNCTION Switch
Main generator provides dc level output.
DC
Main generator provides sine wave output.
(Sine)
Main generator provides triangle wave output.
(Triangle)
Main generator provides square wave output.
(Square)
Main generator provides positive pulse output.
(Positive pulse)
Main generator provides negative pulse output.
(Negative pulse)

TRIG START/STOP
trigger and gate modes, and on sine and triangle waveforms of less

than 2 MHz. A 0 CAL detent ensures standard waveforms start and
stop and 0O.
OUT (600 Ω) Connector
18
Output of modulation generator functions.
Vertically offsets main generator waveform in all functions except DC.
19
DC OFFSET Control
When FUNCTION switch is in DC position the DC OFFSET control varies
polarity and level of DC output. An OFF detent ensures zero offset.
Provides external voltage input for frequency modulating the modula-

FM IN Connector
tion generator.
Varies symmetry of main generator waveforms from 19:1 to 1:19.
21
SYMMETRY (FREQ 10)
An OFF detent ensures 1:1 (50%) symmetry. Main generator
Control
frequency is divided by 10.
Provides external modulation signal input for modulating circuits. Con-

EXT TRIG IN Connector
external signal sources.
Provides fine frequency adjustment of frequency dial setting.
VERNIER Control
24
Selects one of ten frequency multipliers for frequency dial range.
