The PLD-2S driver phase locks two resonant scanners of the same frequency (type SC, except for the subminiature scanners) in a Lissajous pattern to create a circle or an ellipse or to lock two resonant scanners of the same frequency in phase or out of phase. The two identical scanners are ONE FIXED FREQUENCY each, picked from the range of 10 Hz to 16 kHz (e.g.: 10 KHz). Scanner "B" is phase locked to scanner "A" in a MASTER/SLAVE mode.
The phase relationship to the master scanner is set by the factory to customer's requirements (0° to 360°) and is front panel adjustable in the range of +/-45° min. .
The PLD-2S driver can also lock two resonant scanners of the same frequency (type SC, except for the subminiature scanners) to a stable external clock in a SLAVE/SLAVE mode in phase or out of phase.

The system can be used as a "stand alone" unit or can be incorporated into an instrument. Although the scanner can be used in a large temperature range this driver is not recommended for use in temperature sensitive applications.

The PLD-2S-110 or PLD-2S-220 driver is a boxed driver for 110V or 220V (please specify). The driver has front panel controls for amplitude and phase and internal power supplies. The dimensions of the cased driver are: 12 X 10 X 3.8"
The PLD-2S-110/220 is a boxed driver with a line switch selector for operating from a line voltage of 110Vac or 220Vac.
The PLD-2S-PC driver is a printed circuit board level driver which requires an external +/-15V DC power supply.
