The AVR models are high-voltage pulse generators capable of driving 50Ω (or higher) loads and operating over a wide pulse width range. The instruments include IEEE-488.2 GPIB and RS-232 interfaces. For diode loads, these models can be used to provide up to 1, 2, 4, 5 or 8 Amps of pulsed current if the diode is connected in series with 50Ω. Most models operate over a wide pulse width range of 100 ns to 100 us.
Model AVR-1A-B provides amplitudes of up to 50 Volts with rise times of 10 ns. The pulse repetition frequency (PRF) is variable from 1 Hz to 100 kHz, provides average output powers up to 25 Watts and a maximum duty cycle of 50%.
Models AVR-2A-B and AVR-2B-B provide up to 100 Volts with rise times of 10 ns, and repetition rates up to 100 kHz. These models provide average output powers up to 50 and 100 Watts with maximum duty cycles of 25 and 50%, respectively. Higher power operation (160W, 80%) is optional on the AVR-2B-B. The AVR-3-B provides up to 200 Volts with rise times of 10 ns. The PRF is variable from 1 Hz to 10 kHz. This model will provide peak output power of 800 Watts and average output power of 16 Watts (2% maximum duty cycle). The AVR-3HE-B offers higher maximum PRF (to 100 kHz), higher duty cycles and average output powers (10% / 80W standard, 20% / 160W optional.)
The AVR-3HF-B offers higher amplitudes (up to 250V), and and a standard maximum duty cycle and average power of 4% / 50W (optionally 8% / 100W or 16% / 200W). The AVR-4-B provides up to 400 Volts out with rise times of 15 ns, and pulse widths variable from 100 ns to 100 us. The PRF is variable from 1 Hz to 10 kHz. This model will provide peak output power of 3.2 kW and a standard maximum duty cycle and average power of 4% / 50W (optionally 3.1% / 100W or 6.2% / 200W).
