Operating Instructions
Before applying power to unit, make sure that input voltage setting is correct and
the ventilation holes are not blocked. Ensure that Ventilation Fan is working well.
It is necessary to inspect the generated signal with an oscilloscope before con-
necting 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 shows the reading as per present settings.
5.1 FUNCTION GENERATOR OUTPUT
1. Select the type of waveform required by rotary switch of FUNCTION.
2. Select the Range of frequency by rotary switch of RANGE.
3. Connect Main Output signal to Channel 1 of oscilloscope and Sync Out-
put signal to Channel 2 of oscilloscope. Set the trigger source of oscillo-
scope at Channel 2.
4. Set the frequency of the signal by adjustment knob. The display shows
the frequency reading of signal.
5. Adjust the amplitude of the signal Amplitude knob. Pull the knob if the
signal is to be attenuated 10 times.
6. Set the DC Offset of signal by OFFSET knob to required level (-10V to
+10V).
7. Check the impedance of the load before connecting (50W max.).
5.2 SWEEP GENERATOR OUTPUT
1. Connect Main Output to Channel 1 of oscilloscope and SWEEP Output
to Channel 2.
2. Channel 2 displays linear saw-tooth waveform. SWEEP Output is avail-
able regardless of “SWEEP ON” switch. If WIDTH knob is pulled then
LOG sweep will be available.
3. Adjust the Sweep Rate with Rate Knob. (Adjustable from 5S to 10ms).
4. Adjust the starting frequency as explained in Function generation.
5. PULL the Rate Switch to make SWEEP mode ON.
6. Channel 1 will display Sweep wave.
5. Adjust the sweep width with WIDTH knob. (1:1 to 1:100).
