OPERATING MANUAL DIGITAL DRIVER MODULE MODEL NUMBER: MLPXXX-YDC Former Model Number: 21XXX-YDM DOCUMENT NUMBER: 51A14095B This Operating Manual is for use with AOM Drivers with model numbers: XXX = a fixed frequency of between 27 and 300 MHz crystal controlled.
SECTION I INSPECTION PROCEDURE Examine the shipping carton for damage. If the shipping carton or packing material is damaged it should be kept for the carrier’s inspection. Check the contents of the shipment for completeness, mechanical damage, and then test the equipment electronically. Operating procedures are contained in Section VI.
SECTION II. DESCRIPTION The model MLPXXX-YDC is a crystal controlled RF frequency generator designed to supply a signal of XXX MHz, where XXX is a fixed frequency of between 27 and 350 MHz, up to two Watts maximum output and is used to drive the Gooch and Housego 15000, 23000, 24000, 26000 free space series and fiber coupled series acousto optic modulators.
SECTION III SPECIFICATIONS PARAMETER: SPECIFICATION: Output Frequency: XXX MHz Where XXX = a fixed frequency of between 20 and 350 Frequency Stability: + 0.01% Quartz Stabilized Spurious Levels: -50 dBc Maximum Harmonic Distortion: -15 dBc Maximum Digital Input: TTL Levels: TTL HIGH = Full RF Power TTL LOW = Minimum RF Power Output Frequency:...
SECTION V CONTROLS AND CONNECTIONS A. RF Out BNC - Female RF Power Output – The output is a factory set, crystal controlled, fixed frequency of between 20 and 350 MHz with an output power set nominally to 0.4, 1, or 2 Watts. When purchased with a Gooch and Housego AOM the output power will be set to give optimum performance.
SECTION VI TESTING PROCEDURES • With the power off, attach a 50 Ohm load capable of dissipating 2 Watts to the "RF Output" of the unit. Apply +24 Volts to the 24V INPUT solder post of the module and return to the Ground Lug. Apply a TTL High to the Modulation Input port through a 50 ohm cable.
OPERATION PROCEDURE: • The driver should be pre-set to output RF power at the required power level for the AOM. • With the power off, attach the Gooch and Housego 15000, 23000, 24000, or 26000 free space or fiber coupled acousto optic modulator or other acousto optic modulator device to the driver with a 50 Ohm cable.
