Maximum amplitude: +- 20 volts
Minimum amplitude: +- 1.8 volts
Optimum amplitude: +- 4.5 volts
Minimum Frequency: 0 Hz (DC)
Maximum Frequency: 20 MHz (greater with a low impedance source)
Solder type: Lead free
DNA slot size: 3.0 mm
Connector Type: BNC 50 ohm
When using a boost cable, you can set the amplitude to 1.8V and still achieve the min requirement per the specifications. However, if wired directly, recommend 4V to achieve +-2V.
Personally I use 5, 10 and 20V depending on what I'm doing and what waveform I'm using.
