<15 nanoseconds, and pulse widths continuously adjustable from <40 nanoseconds to DC. The pulser operates on +24VDC to +28VDC support power, and features integrated DC high voltage power supplies. The PVM-4210 is optimized for differential drive of deflection plates for electrostatic modulation particle... - Page 6 0 to 950V using screwdriver-adjustable potentiometers readily accessible on the end panel of the pulser module. The PVM-4210 requires +24VDC to +28VDC support power and a TTL (into 50Ω) gate signal. For safety and control flexibility, a TTL level signal is used to enable and disable the DC power supplies.

Output Pulse Configuration With Inverted Gate Selected 4.2 Power Supply Enable For safety and flexibility, the PVM-4210 features a power supply enable input (DSUB connector pin 14). In order to enable the DC power supplies (and therefore generate an output pulse), this input must be held HIGH. This can be done in two ways: 1. -

5.1 Output Cabling The PVM-4210 is designed to drive capacitive loads with fast rise times. Since the current out of the PVM-4210 is limited, the lower the capacitance, the faster the risetime. -

Monitor the voltage across the load, utilizing an appropriate high voltage probe or attenuator. 4. Apply +24VDC to +28VDC power to the module, and apply a TTL level power supply enable signal (or close the switch to connect pin 3 to pin 14 as described above). -
