(2) PUSH TTL Knob (CMOS Level Control Knob)
12
Pulling the contro! varies the level of CMOS
square
waves from 5Vpp to 15 Vpp continuously.
Rotating the knob, if it is depressed, causes no
variation in the level of TTL square waves.
AMPLITUDE
Control
Rotating this control varies amplitude of output
waveform.

COUNTER
EXT Selector Pushbutton
Pressing the pushbutton (button engaged ) selects
external input frequency. Another press (button
released ) selects internal oscillation frequency.
dé) COUNTER
—20 dB Pushbutton
Pressing the pushbutton attenuates counter input
signal by 20 dB.
4),48)
ATTENUATOR Pushbuttons
Pressing these pushbuttons attenuates output signal
by 20 dB and 40 dB respectively.
FUNCTION
Selector Switch Assembly
Selects output waveform out of sine wave ("_),
triang! wave (" ), and square wave (",).
TTL/CMOS
Output Jack
Outputs TTL—level or CMOS square waves.
EXT COUNTER
Input Jack
Input jack for measuring frequency of external signal.
VCF
Input Jack
Application of voltage from 0 to 10V varies
frequency up to max.
1000:1.
OUTPUT
Jack
Outputs sine wave, triang! wave, or square wave
