Method of operation: The rising edge of the Trigger signal (see picture) initiates the transducer charging process. After a predetermined time, the end of charge of the transmitter occurs and the ultrasonic pulse trigger (falling edge pulse output) is generated. At the same time a pulse Trig output is generated. • • • • Pulse amplitude: 100V - 1250V Duty factor: 50% - 95% Frequency: 0.7 – 164Hz Trigger output/input: TTL Trig. input Pulse output Trig. output

Working modes Generator can work in two modes: • Setting (SET) mode which allow to set parameters using potentiometers, available on the front panel. The generator is also normally working in this mode, but not necessarily stable. • Normal work mode (RUN). In this mode the possibility of changing the settings is blocked. The generated signal is stable in this mode. Trigger: • INT – Internal trigger • EXT – External trigger. In both cases trigger signal is sent or received by BNC (TRIG) connector on the rear panel. Trigger pulse is sent out after the transducer is discharged. In the case of...
