© PUSH T T L Knob ( C M O S Level Control K n o b )
Pulling the control varies the level of C M O S square
waves f r o m 5Vpp to 15 Vpp continuously.
Rotating the knob, if it is depressed, causes no
variation in the level of T T L square waves,
@ A M P L I T U D E Control
Rotating this control varies amplitude of output
waveform.
@ Frequency Range/Gate Time Selector Switch Assembly
Selects the following seven ranges of oscillation
frequency or four ranges of gate time :
X 1 : 1 0 s
X 1 0 : A
X 1 0 0 : • 1s
J
X 1 k :
X 1 0 k : 0.1s
X 1 0 0 k :i
0.01s 0.01s
X 1 M : I
(§) C O U N T E R E X T Selector Pushbutton
Pressing the pushbutton (button engaged) selects
external input frequency. Another press (button
released) selects internal oscillation frequency.

0.2 Hz to 2 Hz
2 Hz to 20 Hz
20 Hz to 200 Hz
0.2 kHz to 2 kHz
2 kHz to 20 kHz
20 kHz to 200 kHz
0.2 MHz to 2 MHz
@ C O U N T E R - 2 0 dB Pushbutton-
Pressing the pushbutton attenuates counter input
signal by 20'dB.
@ , @ A T T E N U A T O R Pushbuttons
Pressing these pushbuttons attenuates output signal
by 20 dB and 40 dB respectively.
@ F U N C T I O N Selector Switch Assembly
Selects output waveform out of sine wave
triangl wave ( / \ / ) , and square wave ( H - i ) •
@ T T L / C M OS Output J a c k
Outputs T T L - l e v e l or C M O S square waves.
® E X T C O U N T E R Input Jack
Input j a c k for measuring frequency of external signal.
® V C F Input Jack
By applying voltage to this jack in the state where
the W I D T H pushbutton(8)is depressed (button engaged),
frequency of output signal can be varied.
Application of voltage from 0 to 10V varies
frequency up to max, 1000:1.
(§> O U T P U T J a c k
Outputs sine wave, triangl wave, or square wave
selected with the F U N C T I O N selector switch assembly
