OPERATING INSTRUCTIONS

WARNING: Before applying power to your GF-8056, make sure that the input voltage setting is correct for your
power source.
CAUTION: All the knobs are set to "PUSH" position on operation if not special marked to be set at "PULL".
(A) Function Generator and Inspection
1. Turn on the power switch and make sure the
LED's of the 5-digit display light.
2. Connect MAIN OUTPUT BNC of the GF-8056 to
CH1 input BNC of your Oscilloscope, and the
SYNC OUTPUT BNC to CH2. Set the trigger
source of your oscilloscope to CH2.
3. Turn the FREQUENCY knob from x0.05~x5.0
The GF-8056 display and oscilloscope will be
changed slightly on each step.
4. Turn the RANGE knob from x1~x1000. You will
find the 5-digit LED display value will change 10
times on each step and the oscilloscope too.
When the switch (7) is set at Hz or kHz, the
display value will be changed to x1 or x1000.
5. Turn the FUNCTION knob to select the waveform
output to CH1 of your Oscilloscope. CH2 will be
TTL square wave only.

6. Turn the AMPLITUDE knob to adjust the
amplitude of the signal output to CH1. When you
"PULL" out the switch, the amplitude will be
reduced 20 times (–20dB), but the display of CH2
(sync output signal) will be unchanged.
7. Turn the OFFSET knob. You will find that CH1
and CH2 will not change. This switch will operate
only in the "PULL" position. PULL out the offset
switch and turn it to set DC offset voltage (from
+10V to –10V) of the main output signal. Note
that the SYNC output signal will be not affected.
Note: When the offset voltage is higher than the
wave (+ or –), the display waveform will be cut OFF.
