Also I found a low frequency signal generator on Ebay with the below specifications. Does this look like what I need to do this sort of work?

Specification:
Frequency range: 10Hz-1MHz, 5 files
Accuracy: full scale ± 5%
Output impedance: 600Ω
50: negative 50 dB, and can fine tune

Sine Wave Output:
Output voltage: 5-6V RMS
Distortion rate: 500Hz-50KHz is not greater than 0.05%, 50Hz-500KHz not greater than 0.5%
Output smoothness: 1KHz reference ± 1.5dB

Square Wave Output:
Range: 10Hz-1MHz
Output level: 10V peak value
Rise time: 0.5 microseconds

Synchronization Performance:
Range: 1V voltage per input can change the oscillation frequency 1%
Input impedance: 10KΩ
