PRL-4108U Specifications

Mini Modular Instruments > Fanout Buffers > PRL-4108U > Specifications

(0° C ≤ TA ≤ 35° C)*

Unless otherwise specified, dynamic measurements are made with all rear-panel outputs terminated into floating 124 Ω, using 124 Ω shielded twisted pair Triax cables (Trompeter P/N PCGOW10PCG-36 or equivalent). Channel to channel skew and propagation delay measurements are made using a PRL-425NTR Differential Receiver with NECL outputs. Rise and fall time measurements are made using a Triax to SMA adapter and connecting the SMA outputs to a 50 Ω input scope.

Please contact sales@pulseresearchlab.com for performance specifications on other models.

Notes:
(1) Due to lack of suitable equipment with floating differential 124 Ω input termination, tR and tF are measured using a 50 Ω input scope.
