Model 202H300V Pulse 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).

TIMING
Trigger
Internal 0.01 Hz to 500 kHz; external 0 to 500 kHz. Rates to 1 MHz at lower amplitudes.
Pulse Width
15 ns to 5mS (see Droop). Calibrated at 300 V; at lower amplitudes true widths increase slightly in fixed value up to 10 ns max.
Duty Factor
1% max. at 300 V. Duty factors increase up to 25% at 20 V.
Delay

Module Delay
55 ns typical (fixed) mainframe's Pulse Out to module's Pulse Out. Jitter 25 ps rms.
MEMORY STORAGE
A ROM determines the instrument's allowable operating conditions and units of display applicable for the installed module.
A nonvolatile memory (RAM) in each module stores up to ten complete settings of operating conditions (trigger level, slope, etc.) and output pulse parameters.
RECALL
The RAM-stored settings can be manually or bus transferred to the mainframe to produce the predetermined outputs.
