50V, PRECISION PULSED PULSE GENERATOR
Output Voltage +50V Output Current Maximum Duty Cycle Pulse widths from <1µS 100µS Instrument-quality analog voltage current monitors data acquisition Designed precision pulsing semiconductor devices pulsed characterization
PVX-2505 pulse generator designed pulsed (current-voltage) characterization semiconductor devices Volts Amps. also well suited other applications requiring high current, precision voltage pulses. characteristics semiconductor devices functions frequency temperature. Curve tracers other "DC" test systems typically step through range gate voltages and, each gate voltage, sweep drain voltage over measurement range. device essentially reaches thermal equilibrium electronic (semiconductor-trap) equilibrium each point, yielding different test characteristics than actual operational characteristics. pulsing device using PVX-2505 taking measurement during pulse, measurements taken before device heats This circumvents thermal effects associated with conventional "DC" testing, more closely approximates characteristics device when operating high frequencies, doesn't activate semiconductor "traps". PVX-2505 designed using bi-directional MOSFET output stage using DEI's DE-Series Fast Power MOSFETs. This design provides fast rise fall times, with minimal overshoot, undershoot ringing fast settling times. This controlled voltage waveform allows device under test (DUT) stabilize voltage within hundred nanoseconds, allowing measurements made before device heating begins.
quiescent (bias) voltage applied pulse generator, allowing held voltage other than zero, then pulsed above below this voltage. PVX-2505 requires input gate signal, pulse (VHIGH) optional quiescent (VLOW) power supply inputs. output pulse width frequency controlled input gate signal. output voltage amplitude controlled amplitude input VHIGH optional VLOW power supply amplitudes. front panel controls monitors provide flexibility operate pulsed mode, switch mode, which voltage generated VHIGH power supply applied directly DUT. Integral instrumentquality voltage current probes provided facilitate pulse data acquisition. output pulse launched innovative, lowimpedance cable. design this cable maintains fidelity output pulse without introducing pulse distortion ringing, provides convenient means connecting pulse generator bias tee. pulse generator direct-coupled, air-cooled solidstate design, offering equally fast pulse rise fall times, power dissipation, minimal over-shoot, under-shoot ringing. over-current detection shut-down circuitry protect pulse generator from potential damage arcs shorts load interconnect cable.
