1. Power Adapter: Generator requires 12-VAC adapter (do not use DC types).
2. Power Switch: Turns power on and off.
3. Multiplier: Selects generator frequency range as a power of 10 (1 Hz to 1
MHz).
4. Frequency: Varies frequency from 1 to 10 times the Multiplier setting.
5. Amplitude: Adjusts output amplitude from 0 to 12-volts p-p.
6. DC Offset: Adjusts DC bias on waveform from -6 to +6 VDC.
7. Waveform: Selects square, triangle, or sine waveform output.
8. Output: Binding posts provide connection to device under test.
To set for a given output signal, first select the desired increment using the
Frequency control. Then, set the desired Multiplier. For example, a Frequency
setting of 5 and a Multiplier of 10
2 yields a 500-Hz (5
×
10 2 ) signal. Amplitude
is calibrated in volts p-p. To obtain low-level signals for AF amplifier testing,
install a 10:1 or 100:1 voltage divider across the output terminals using 1/4-watt
resistors. At low signal levels, the use of a shielded test cable is recommended.
