(B) Sweep Generator
1. Turn on the power switch and make sure the
LED's of the 5-digit display light.
2. Connect the main OUTPUT BNC to the CH1
input BNC of your oscilloscope.
3. Connect the SWEEP OUTPUT BNC to the CH2
input BNC of your oscilloscope and set the
trigger source of the oscilloscope at CH2.
4. Turn the SWEEP RATE knob.
oscilloscope will display a linear sawtooth wave
and the frequency will be variable from 5sec to
10mS by turning the switch. CH1 will display the
wave according to the FUNCTION switch
position. PULL out the switch to set "SWEEP
ON". The display of CH2 will be unchanged and
the display frequency will be varied by turning the
knobs. Note that the display of CH1 will be a
sweep wave, and the speed will depend on the
sweep rate.
NOTE:
After "PULL SWEEP ON", the trigger
source of the oscilloscope must be changed from
CH2 to CH1.
5. Turn the SWEEP WIDTH knob to adjust the
sweep width display on CH1.
NOTE: Be sure that the SWEEP RATE SWITCH
was at the "PULL" position. When pulling out the
sweep width switch, the sweep mode will change
from linear to log sweep. The waveform display of
CH1 will become log form.

This frequency will be the start frequency. After
"PULL SWEEP ON", the sweep condition,

8. V.C.F. INPUT - Set the sweep rate switch at the
"PUSH" position to set the GF-8056 at normal
generator mode. Connect the sweep output BNC
to V.C.F. INPUT BNC and check the waveform
displayed on CH1 of the scope. The waveform
displayed should be the sweep wave.
inputting a sine wave from another generator to
the V.C.F. INPUT to observe the FM display, be
sure the frequency of the basic wave (GF-8056)
is higher than the external input signal.
