5 Operating Instructions
5.1 Pulse Generator Output
Before applying power to the unit, make sure that input voltage is correct and the
ventilation holes are not blocked. Ensure the ventilation fan is working well. It is
necessary to inspect the generated signal with an oscilloscope before connecting it to
any electronic circuit. Hence, use of oscilloscope is mentioned in the procedure. Turn
on the instrument with power on switch provided on the front panel. The display LED
will light up.
1.
Select the type of waveform required by adjusting the corresponding knobs by
following the steps below.
2. Select the type of triggering you require. If you want to use standard
triggering, set the MODE KNOB to INT RATE.
3. Connect the main output signal to CH1 of oscilloscope and the SYNC output
signal to CH2 of oscilloscope. Set the trigger source of oscilloscope to CH2.
3. Set the output frequency of the signal with the RATE KNOBS. The display
shows the output frequency at all times.
4 Adjust the output waveform shape by adjusting the WIDTH KNOBS. The output
of the generator should be reflected on the display of the oscilloscope on CH1.
5. Adjust the amplitude of the signal with the LEVEL KNOB.
6. Observe the output level changing on the display of the oscilloscopes on CH1.
Note: Check the impedance of the load before connecting. To get an accurate
representation of the signal and prevent reflection, it is important to match this
impedance to the output impedance of the function generator.
5.2 Using Manual Trigger
In order to use the manual trigger, you must have the "Rate" switch in the
10M/100nS position. This is the only way to access the manual trigger function. If you
set the Rate switch to the 10M position and the "Width" switch to the 50mS and the
"Mode" switch to manual trigger, then set the volt/division switch on your O-Scope
to 2V or 5V and your time/division respectively at 50mS. When you push the manual
