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)
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..
Auto Sweep
(1) Select the
Function (8)
button, select the
Range (7)
, and rotate the
FREQUENCY (13)
knob to set the required base
frequency.
(2) Connect the
OUTPUT
terminal
(22)
to the oscilloscope for observing the OUTPUT signal.
(3) Rotate the
FREQUENCY (13)
knob to determine the upper limit frequency.
(4) Pull out the
FREQUENCY (13)
knob to activate auto sweep operation.
(5) Rotate the
SWEEP/TIME (14)
knob and
SWEEP RATE (16)
knob to adjust sweep time and rate.
(6) The LOG sweep mode is selected by pulling out the
SWEEP/TIME (14)
knob.
Note: The sweep width can only be adjusted during the sweep cycle and it cannot be stopped.
AM/FM operation
(1) Select the
Function (8)
, select the
Range (7)
, rotate the
FREQUENCY (13)
knob to set required frequency.
(2) Connect
OUTPUT
terminal
(22)
to the oscilloscope for observing the output signal.
(3) For the FM modulation mode, press the
MOD (15)
button and pull out the
MOD/DEPTH (16)
knob.
(4) For the AM modulation mode, press the
MOD (15)
button and push in the
MOD/DEPTH (16)
knob.
(5) Adjust the
MOD/DEPTH (16)
knob to achieve required modulation ratio.
