Description

 

G4-143x series

 SGMW-x series


    The G4-143x series is fully packaged sweeper source. The microcomputer is integrated into the device provides total control of the system. The sweeper self-tests at turn-on. Two independent DAC’s control frequency and output power. Minimal built-in full band sweep time is 10ms. User from front panel or GPIB bus controls power, initial and final frequency, time of sweep, internal amplitude modulation. Various programs of power and frequency change are provided including 10 user-defined programs. There are two inputs for external frequency and power control. The rugged High Voltage power supply is specially designed to withstand the rapid voltage changes inherent in BWO deceleration. Each generator is individually calibrated for output power versus frequency, with different power levels and frequency versus control voltage relationships.

     The SGMW-x series is fully packaged sweeper source.  The sweeper consists of external module with BWO-X series and power supply.  There are all the electronic circuitry and power supplies required to provide the operation of BWO. The sweeper self-tests at turn-on. BWO tube is fully protected against improper voltage connections.  There are two inputs for external frequency and power control. Phase locking possibility is provided. Minimal built-in full band sweep time is 10ms. One power supply can be used with different BWO. Particularly, the remote module with BWO tube allows using it at hard-to-reach places and can be installed quite away, somewhere near a scientist’s work desk. Another great advantage of this series of BWO sweepers is its power supply unit, that allows feed up to few BWO tubes even with different working frequencies.  Download operation manual for SGMW-x here
