1. POWER SWITCH

Push the switch “ON” will light the LED of the digits (14) to indicate

power “ON”.

2. FREQUENCY CONTROL KNOB

Used to adjust the required frequency for selected range with the multi-

plication factor of 0.04 to 4.0.

3. SYNC OUTPUT

The TTL level square signal Output synchronous with frequency of Main

Output.

4. SWEEP OUTPUT

Sweep signal is available regardless of position of SWEEP ON switch

provided with Sweep Rate Knob.

Function Output signal provides normal mode or sweep mode output

depending on mode selected. The maximum Output impedance is 50Ω.

6. AMPLITUDE KNOB

The amplitude of signal can be adjusted from 0.1Vp-p to 20Vp-p at No

Load. Pull the Knob to attenuate the signal 10 times.

7. DC OFFSET

This Knob can apply a DC Offset to Main Signal. Turn the Knob

clockwise for Positive Offset and anti-clockwise for Negative Offset.

8. SWEEP RATE
