The EndRun PDC3301 Distribution Chassis is a dual-input, ten-channel, pulse distribution amplifier in a 1U rackmount chassis. It provides ten isolated copies of an input signal. Fault sensing of signal levels is provided on all inputs and outputs, and the fault status is easily visible via front-panel LED indicators. This chassis performs intelligent failover switching via continuous monitoring of the input pulse rates. It can switch inputs without missing a pulse for rates less than or equal to 1 MPPS and pulse widths greater than or equal to 500 nanoseconds. The PDC3301 features very high isolation between output channels. Power supply voltages are post regulated and all output buffers are individually regulated. This feature ensures that minimal phase disturbance of adjacent channels occurs due to the accidental shorting or unterminating of an output.
