FEATURES AND ADVANTAGES
- Automatically regulated feedback amplifier
- Improves the amplitude stability of the device
- Provides sine wave and TTL square wave reference signals
- Trim pot for adjustment of 180° of the phase of the reference signal
- Trim pot for amplitude adjustment
The AGC driver, a close loop feedback amplifier, operates a broad range of resonant optical scanners
and resonant optical choppers at their natural frequency.
The AGC driver has an Automatic Gain Control circuit which automatically regulates the motion amplitude of the
resonant device. It improves amplitude stability by approximately 10 times compared to the
unregulated drivers and provides precise control for a wide temperature range.
Both sine wave and TTL level square wave are provided as reference signals.
A trimpot control permits the user to adjust the phase of the reference signals with respect to
the position of the mirror or the vane. The adjustable range is 180°.
A second trimpot provides amplitude adjustment in the range of 10% to 100% of the full amplitude.
The AGC type driver is available as:
Model AGC-PC A board level driver that requires an external +/-12V to +/-15V dc power supply.
Model AGC-110 or AGC-220 A cased driver (5.3" × 5.3" × 2") operating from a line voltage of 110V ac or 220V ac.
Model AGC-110/220 A cased driver (5.3" × 5.3" × 2") with a line switch selector for operating from a line voltage of 110Vac or 220Vac.
Each of these drivers can be available in the following feature:
A feedback amplifier to control the scan amplitude set by an external voltage input.
There is no additional cost for the added feature.
+/-12V to +/-15V dc, 0.3 Amp max. for the AGC-PC Driver
