5-2.Triangle, square and sine wave
(1)
First select Function
8
, and select Range
7
, rotate FREQ
13
, to
set the required frequency (read out from display window).
(2)
At this moment, connect Output
, to oscilloscope for observing
output signal, or connect to other experiment circuit.
(3)
Rotate AMPL
12
again to control waveform amplitude.
(4)
If attenuation output signal is required, pull out AMPL
12
knob to
obtain 20dB attenuation or press
knob for additional 20dB
attenuation.
(5)

, rotate FREQ
13
to set required frequency
range.
(2)
Connect BNC connector of TTL/CMOS
to oscilloscope or to
other experiment circuit for observing output signal.
(3)
At this moment, output is square waveform fixing to TTL level;
s
uits for general TTL integrated circuit.
(4)
If square waveform of CMOS level is required, can pull out CMOS
10
knob to adjust voltage level.
