1

LCD DISPLAY

16 Character X 1 line display shows frequency of  output signal set by FREQUENCY KNOB (2) and UP RANGE(9) or DOWN RANGE (10) switches. It also displays the output  waveform selected by WAVEFORM SELECTOR (8).

2

FREQUENCY

In conjunction with UP RANGE/FREQUENCY (9) or DOWN RANGE/FREQUENCY (10) switches this knob varies the output  frequency of  the waveforms at  the  50  ohms OUTPUT JACK (6).

3

PULSE WIDTH   

This control varies the duty cycle of the selected pulse from 15% to 85%.

4

DC OFFSET

Turns on/off the DC offset voltage applied to the output and controls  the  output  signal  DC  level  with  respect to ground. It is  continuously  variable for ± 5V. Its range is attenuated by the ATTENUATOR (7) switch.

5

AMPLITUDE

It adjusts the amplitude of  the  output signal from less than 10% to 100% of the levels, selected with the ATTENUATOR (7) switch.

6

OUTPUT JACK

Waveforms  selected by  WAVEFORM  SELECTOR (8) switch as   well   as   the  superimposed   DC  offset  voltages  are  available at this jack.

7

ATTENUATOR

This switch adjusts the amplitude of output signal in precise steps of 20 dB. Maximum attenuation obtained is 60 dB.

8

WAVEFORM SELECTOR

Selects either sine, square, triangle or pulse as the output waveform.

9

UP RANGE /   FREQUENCY

In Switch mode increases frequency at digit position set by FREQUENCY  KNOB (2). In Pot mode used  in  conjunction with  FREQUENCY  KNOB  to  select the  desired  output  frequency. Each press of the switch increases the frequency by factor of 10.

10

DOWN RANGE / FREQUENCY

In Switch mode decreases frequency at digit position set by FREQUENCY  KNOB (2). In Pot mode used  in  conjunction with  FREQUENCY  KNOB  to  select the  desired  output  frequency. Each press of the switch decreases the frequency by factor of 10.

11

POWER ON-OFF

Turns on/off the mains supplied to the unit. Located on the back panel
