<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 spectrometers and accelerators. It will also drive any high impedance,... - 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 50 ) gate signal. For safety and control flexibility, a TTL level signal is used to enable and disable the DC power supplies.

CV capacitance, including the capacitance of the load, interconnect cable, and the internal capacitance of the PVM-4210, V is the pulse voltage, and F is the pulse repetition frequency (or the total pulses per second). (For these calculations, the internal capacitance of the PVM-4210 is 125pF, and Belden 8218 cable is 21.5pf/foot.) Given the maximum power supply capability of 4W (4mA) per... -

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. -
