The PLD-1S driver phase locks any resonant scanner (type SC) to an external clock signal, to provide an ultra stable scanning beam motion [sub] system. The system can be used as a "stand alone" unit, in the laboratory, or can be incorporated into a larger instrument/system. The phase relationship to the clock is factory set to customer's requirements (0° to 360°), and is front panel adjustable in a range of +/-45° min. The driver can be a fully integrated driver with front panels controls and internal power supplies or a printed circuit board level driver. The dimensions of the cased driver are: 12" × 10" × 3.8". The PLD-1S-PC driver is a printed circuit board level driver which requires an external +/-15V DC power supply.

FRONT PANEL CONTROLS
POWER	Power switch to turn the drive "ON"
SYNC INPUT	External clock input (TTL or sine wave), BNC connector
LOCKED MODE	The scanner is phase locked to the clock signal
OSCILLATOR MODE	The scanner is self oscillating at its resonant frequency (not locked to the clock input)
PHASE CONTROL POT	To adjust the phase of the scanner in relationship to the clock, +/-45°C min.
POSITION MONITOR	Scanner position output, BNC connector
AMPLITUDE CONTROL	Scan amplitude adjustment POT
OUTPUT	Output connector to interconnect to the scanner
