Triangle, square, and sine waves
(1) Select the
Function (8)
, select the
Range (7)
, and rotate the
FREQUENCY (13)
knob to set the required
frequency (read output in
display window (4)
).
(2) Connect the
Output (22)
terminal to the oscilloscope for observing the waveform signal.
(3) Rotate the
AMPL (12)
knob to control the waveform amplitude.
(4) If attenuation of the output signal is required, pull out the
AMPL (12)
knob to obtain 20dB attenuation or press
the
ATT -20dB (12a)
button for additional 20dB attenuation..
(5) The phase-relation of Output waveform and TTL output is shown in Figure 5 below:

Pulse wave generation
(1) Press the
Function (8)
button (
), select the
Range (7)
,
and rotate the
FREQUENCY (13)
knob to set the frequency.
(2) Connect the
OUTPUT terminal (22)
to the oscilloscope for
observing the output signal.
(3) Pull out and rotate the
Duty (9)
knob to adjust the width of
pulse waveform.
(4) Adjust the
AMPL (12)
knob to control the pulse amplitude.
(5) Pull out the
AMPL (12)
knob to attenuate the output signal by 20dB.
Ramp wave generation
(1) Press the
Function (8)
button (
) , select the
Range (7)
, rotate the
FREQUENCY (13)
knob to set the
frequency.
(2) Connect the
OUTPUT terminal (22)
to the oscilloscope for observing the output signal.
(3) Pull out and rotate the
Duty (9)
knob to adjust the slope of ramp waveform.
(4) Adjust the
AMPL (12)
knob to control output amplitude of ramp waveform.
(5) Pull out the
AMPL (12)
knob to attenuate the output signal by 20dB.
TTL/CMOS signal output
(1) Select the
Range (7)
, and rotate the
FREQUENCY (13)
knob to set the frequency.
(2) Connect BNC connector of
TTL/CMOS (20)
to oscilloscope to observe the output signal.
(3) The output is a square waveform fixed at TTL level, suitable for general TTL integrated circuits.
(4) If a square waveform of CMOS level is required, pull out the
CMOS (10)
knob and adjust to required voltage
levels.
Variation of external voltage-controlled frequency (VCF) (FG3C-UA only)
This mode of operation allows the user to adjust the frequency of the Function Generator with an external DC
control Voltage.
(1) Select the
Function (8)
, select the
Range (7)
, and rotate the
FREQUENCY (13)
knob to set the required frequency.
(2) Connect external control voltage (0 ± 10VDC) to the
VCF (21)
terminal via a suitable lead, and observe the signal
generated from the
Output (22)
BNC terminal.
(3) Other adjustments; the
AMPL (12)
knob can change the amplitude of signal, or attenuate the signal; the
Offset
(11)
knob is for DC level changes, rotate the
Duty (8)
knob to change the output ratio of pulse or ramp waveform etc..
Sweep (internal) (FG3C-UA only)
(1) Select the
Function (8)
button and select the
Range (7)
.
(2) Connect the
OUTPUT (22)
terminal to the oscilloscope channel 1 for observing the OUTPUT signal.
(3) Connect the rear panel
GCV (23 )
terminal to the oscilloscope channel 2 for observing sweep control signal.
(4) Rotate the
FREQUENCY (13)
knob to determine the upper output sweep frequency.
(5) Pull out the
FREQUENCY (13)
knob to activate sweep operation.
