3. MAINS SELECTOR
This switch select the mains input as either 115V or 230V.
Factory set to 115V.
4. MAINS IN
This is the AC mains input to the Function Generator.
Power input required is 115V ±10%, 60Hz or 230V ±10%,
50Hz.
5. EARTH TERMINAL
This terminal for connection of external earth to the
instrument.
3.3 PRECAUTIONS
To obtain the optimum performance of the 2001A, the following
procedure should be adopted.
1. Select a location free from dust and humidity.
2. Do not operate the instrument where mechanical vibrations
are excessive or near a instrument which generates
strong electric or magnetic fields.
3. Although the output is short circuit protected, DO NOT
intentionally short the output.
3.4 OPERATING PROCEDURE
After power ON, set RANGE switch to desired frequency
range. The frequency can be set by using the frequency dial.
The function switch selects the desired waveform.
The generator output level is set by LEVEL FINE control and
LEVEL RANGE. The RANGE control directly indicates the
output level in p-p.
The variable LEVEL FINE control has a range of approximate
20dB.
The TTL output is available at all times in phase with the
Function generator output. This can be used for various
applications like trigerring an oscilloscope sweep or as a
independent output to measure the frequency more accurately
on a Frequency counter or directly interfacing to digital
circuits.
Note :
1) To get full sweep range from DC voltage input applied at
SWEEP IN terminal ensure frequency dial at minimum
position for 0 to +10V input and keep frequency dial at
maximum position for 0 to -10V input. A bipolar ac signal
will produce a sweep up & down from the set frequency.
2) Total sweep range is function of frequency dial position
and input voltage at SWEEP IN terminal.
3) Frequency dial sweep range is 10:1 while frequency
sweep range of 100:1 is possible by means of external
sweep input 0 to ±10V as per specification given above.
