Description
The SHF C603 A is a 2:1 Multiplexer operating at data rates up to 120 Gbps for use in broadband test
setups and telecom transmission systems. Two single ended serial data streams of up to 60 Gbps are
accepted by the multiplexer and converted into one differential data signal of up to 120 Gbps. A single
ended clock signal with a frequency half of the output data rate drives the SHF C603 A. All RF in- andoutput ports are AC-coupled and internally terminated with 50 Ohm to GND. Unused in- or output ports
should be terminated with 50 Ohm.

Remote Interface & Software
The MUX is controlled by the easy to use software package SHF Control Center (SCC). The amplitude,
the duty cycle and the RF output state (on/off) can be set and is displayed in the graphical user interface(GUI).

The measurements below had been performed using a SHF 12104 A Bit Pattern Generator (PRBS 2 -1)
and an Agilent Digital Communication Analyzer (DCA) with a Precision Timebase Module (86107A) and a70 GHz Sampling Module (86118A). The outputs of the MUX module had been connected directly to theDCA input.
