1 ompact Low Power RF Driver: For cousto-optic Q-Switch or Modulator QXXX-YYD-ZZZ-V Former Model Numbers: R0XX-YYDMZZZ & MQ0XX-YYDZZZ-V Description: The QXXX-YYD-ZZZ-V module is a compact Low Power RF Driver, designed to drive an O Q-Switch or O Modulator. The unit has two digital modulation inputs: and. These controls allow the customer to issue a pulse command of a "" pulse width, the duration determined by the Driver's pulse width control, settable by the customer, or issue a "" pulse command, the duration determined by the input signal s pulse width. The output power is controlled by the analog input, where the mode of operation is defined by ZZZ = 0 normal analog mode, or R0 analog switched to full RF mode or a triggered RF Ramp Down mode where ZZZ = FPS first pulse suppression mode or PPK pre-pulse kill mode. Other variations of these modes are also available. The choices of Frequency (XXX), Output Power (YY), and Power ontrol (ZZZ) option are "Factory Set" when ordered. This driver has a Zero rossing function where the output pulse can be synchronized to the zero crossing point of the RF Energy. When enabled the pulse to pulse stability is improved. This product conforms to the requirements of the European Union Directive 20/6/EU of the European Parliament and of the ouncil on the Restriction of the Use of ertain Hazardous Substances in Electrical and Electronic Equipment. Key Features: 2, 2., 0.6, 6, 0, or 0 MHz RF Frequency (XXX) 0.0% Quartz Stabilized Up to 2 watts RF power output (YY) Two TTL Digital Modulation Inputs: fixed and variable pulse width. Up to MHz pulse rate in Q-Switch applications. Up to 0 MHz pulse rate in pulse picking applications nalog Modulation or Triggered RF Ramp Down Mode (ZZZ) Synchronization to RF by Zero cross Fault Protection on Low Power, High Power, and High V Operates on, or 2 VD (V) (Factory set) pplications: Powering an cousto-optic Q-Switch used to spoil the Q of a W laser so as to output an intense pulse of light.
