Model 202H | 300V High Voltage Pulse Electrical Module
Fast High Voltage Pulses with Delay and Width Control
The Model 202H is a high-voltage (300V) plug-in module for BNC Model 6040 Mainframe. It offers nanosecond risetimes and very low jitter. The sharp edges of the 202H are ideal for testing components, gating flashlamps, triggering capacitor banks, or other experiments requiring high voltage pulses. The voltage is terminated into 50 Ohms. The pulse amplitude and width are adjustable via the front panel or remote programming. The Model 202H may be triggered with an internal rate generator, external trigger, or external modulation. There is an ECL output, a Pulse Out from BNC Model 6040 Mainframe, and a High Voltage Pulse Out from the 202H module (BNC connector).Overview
