The description sections and FAQ are machine-assisted and can contain errors; where they disagree with the record, the record is correct, and where description sections disagree with each other, Details wins._ ## Summary - Manufacturer: Pulse Research Lab - Model: PRL-4330 - Condition: Used and in Excellent Condition - Price: $995.00 USD - Availability: In stock, 2 available - Warranty: 1-Year Warranty with 30-Day Return Guarantee - ITAR restricted: No - Shipping weight: 3.5 lb, estimated - Shipping dimensions: 12X9X6 in, estimated ## Categories - Test Equipment > Telecom Test > Communications Other (primary) ## Details This unit is a variant of the PRL-4330-SMA; it has been depopulated to provide three sets of 1:7 TTL fanout and without the enable input or input impedance selector switches. This item is the main unit only, no accessories included. Part Number: PRL-4321-SMA-C001 ## Function Provides three independent 1:7 TTL signal fanout channels with 50-ohm impedance matching, accepting single TTL input signals and distributing them to seven identical TTL outputs per channel. Features fixed input impedance configuration without enable controls or impedance selection switches. Operates as a high-speed digital signal distribution amplifier for clock distribution, trigger signal routing, and multi-destination TTL signal broadcasting in test instrumentation and digital circuit applications requiring precise signal timing and minimal skew across multiple output channels. ## Images - - - -
