3.2 MBT-5003 External Connectors
Table 3-1 summarizes the external connectors and identifies the chapter sections that provide
more detailed information. The rear panel connectors are typical for both the MBT-5003-XUR
Up Converter and MBT-5003-XDR Down Converter units. Front panel connectors, if not typical,
are identified as unique to either unit, both in the table as well as chapter sections that follow.

3.2.1.1 REF OUT Connector, Type ‘BNC’ Female
The REF OUT interface is a type ‘BNC’ female coaxial connector provided on the
MBT-5003-XUR Up Converter and MBT-5003-XDR Down Converter front panels. It is
used to supply a 5 MHz signal from the chassis reference oscillator. The impedance is
matched for 50/75
Ω, and provides an output level of 10 ±5 dBm.
3.2.1.2 RF OUT Connector (MBT-5003-XUR only), Type ‘N’ Female
The RF OUT connector is a type ‘N’ female coaxial connector provided only on the
MBT-5003-XUR Up Converter front panel. It provides the upconverted RF output
signal for customer use.
