3.2.1.2 DC Power Connector (Optional)
A standard 2-circuit terminal block with switch and fuse holder
supplies the optional Direct Current (DC) power to the UT-4500-A.
Observe the following:
DC Power Specifications
Input Power 75W maximum, less than 65W typical
Input Voltage 36 to 72 VDC
Connector Type Terminal Block
Fuse Protection Use 3.15A (slow-blow) 20mm fuses.
3.2.1.3 J2A | REF IN, External Reference Input Connector (BNC-F)
The J2A REF IN (External Reference Input) connector is a ‘BNC’ female connector
used to supply a master reference to the entire chassis. The input signal supplied here
by the user is used for phase-locking the internal 10MHz reference oscillator to a
customer-provided 5 or 10 MHz station clock. The impedance is matched for 50/75",
and requires an input level of 0 ±5 dBm.
3.2.1.4 J2B | REF OUT, External Reference Output Connector (BNC-F)
The optional J2B REF OUT (External Reference Output) connector is a ‘BNC’
female connector that provides a 10 MHz reference for customer use. The impedance is
matched for 50/75", and provides an output level of 5 ±3 dBm.
