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 scanner is ONE FIXED FREQUENCY, picked from the range of 5 Hz to 20 kHz. The scanner is a small size, light weigh, low cost and long life device. It requires low power drive electronics and does not radiate electromagnetic interference (EMI). The scanner has high amplitude stability and very low amplitude jitters; wobble is less than 1 arc sec. The scanner is IR, VIS and UV and high vacuum capable. Reference signal and position output available.

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 
 OSC. MODE 
 The scanner is self oscillating at its resonant frequency (the chopper is not locked to the clock) 
 PHASE CONTROL POT 
 To adjust the phase of the scanner in relationship to the clock, ±45° minimum range 
 POSITION MONITOR 
 Scanner position output, BNC connector 
 AMPLITUDE CONTROL 
 Scan amplitude adjustment POT 
 OUTPUT
