ULTRASONIC PULSER OPGUD PR1

OPGUD PR1 is an ultrasonic pulser suitable for work with all ultrasonic transducers with about 500pF - 20nF impedance.
  

The rising edge of the Trigger signal (see picture) initiates the transducer charging process. After this time, the falling edge of the Trig_Out is generated which indicates the end of the transducer charging process and a transistor switch which discharges the transducer is turned on. · 

Pulse amplitude: 100V - 1250V
Duty: 50% - 95%·
Frequency: 0.7 - 164Hz
Trigger output/input: TTL

Generator can work in two modes:

• setting (SET), mode which allow to set parameters with the help of 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 modus.

Trigger:

• INT - Internal trigger
• EXT - External trigger.

In both cases trigger signal is send or received by BNC (TRIG) connector on the rear panel.Trigger pulse is send out after the transducer is discharged.In the case of external trigger mode, the generator reacts to the raising pulse, starting the process of loading and discharging the transducer.
Input/Output of trigger is placed on the rear panel.
