(8) EXT frequency switch: Press this switch, LED window will display EXT signal frequency
or counter value.
(9) Level adjustment: Press level adjustment switch, the light “level” is on, then adjusting
level adjustment rotary can change DC level offset.
(10) Amplitude: The voltage output amplitude will be big while turning it clockwise, and the
value will be small while turning it counterclockwise.
(11) Voltage out: voltage is out via this terminal.
(12) TTL out: TTL is out via this terminal.
(13) VCF: Voltage controlling frequency change input is via this terminal.
(14) SYMMETRY: sym switch, duty adjustable rotary, press duty switch, the light “SYM” is
on; adjusting duty rotary can change the duty of wave.
3. BASIC OPERATION METHODS:
Before power is on, fist check the input voltage, insert the power line into the AC socket in
the rear panel. Set each controlling knob as the following table:
POWER Knob
Spring out
ATTE Knob
Spring out
COUNTER Knob
Spring out
LEVEL Knob
Spring out
DUTY Knob
Spring out
After that, turn on the switch. The function signal generator acquiesce 10k sine wave, LED
window display it’s out signal frequency.
5.1 Deliver the voltage out signal to oscilloscope Y input terminal via amplitude terminal.
5.2 Triangle

sine wave form:
5.2.1 Press sine
、
square
、
triangle wave, the screen of oscilloscope will display sine
、
square
、
and triangle.
5.2.2 Press frequency range selector and rotate the frequency rotation, the waveform on the oscilloscope’s screen and
frequency on LED window will change evidently.
5.2.3 Turn the amplitude rotary to maximum, the wave amplitude on the oscilloscope’s screen will be
≥
20Vp-p
5.2.4 Press “LEVEL”, turn the “level” rotary to max, wave on oscilloscope will move upside, and vise visa. The max change
should be ±10V or more. NOTICE: when signal is over ±10V or ±5V (50
Ω
),the amplitude is limited.
5.2.5 Press “ATTE”, the out waveform will be attenuated.
4. INSTRUMENT ACCESSORIES:
The standard accessories are as following:
(1) Function Signal Generator 1 set
(2) Connect cable 1 piece
(3) Operation manual 1copy
(4) Fuse 1piece
(5) Power cord 1piece
