0-5V Analog Modulation
User Manual
Device Setup
1.1 Power supply connection
Please use power cable to connect the ‘Vcc +24V’ and negative poles of driver
to a power supply.
Incorrect connection to positive and negative electrodes will cause severe
damage of driver and modulator. The drawing of driver is displayed in Figure
1.2 Adjustment of driver output power
Warning
The RF output power of driver has been matched with acoustic-optic device in
factory. Please DO NOT adjust it unless necessary.
When the RF output power of driver has to be adjusted a flat-head screw driver
can be used to turn the small knob ‘Amplitude Modulation’ located on the side
of driver. Turn it clockwise to increase power, and counterclockwise to
decrease power.
1.3 Modulation Input
The ‘Modulation Input’ of driver is for modulation control signal, which is
standard 0-5V analog signal. Use the provided SMA cable to connect it to a
signal source.
1.4 RF Output connection
Use the provided SMA cable to connect the ‘RF Output’ of driver to acoustic-
optic modulator.
1.5 Laser wavelength
An acoustic-optic modulator is wavelength sensitive, i.e., a narrow-band
device. The wavelength of input laser beam must match the nominal wavelength
of modulator. Any wavelength deviation of input laser beam will cause
significant increase of insertion loss.
1.6 Optical fiber connection
All connectors need to be properly cleaned and make sure connector type
matches.
Application Notes
-
Driver cannot run without a load.
Acoustic-optic device and its driver work at high frequency. If the driver is powered on when there is no load connected to it, like an acoustic-optic modulator, then it will be damaged. -
Heat sink for driver
The driver will be heated up in work condition. A heat sink or a big piece of metal plate is strongly recommended for driver installation. High temperature will cause damage to driver. -
Use caution when handle optical fibers.
-
Always cover connectors with caps when they are unplugged.
