UT-4500-A Series Upconverters Revision 1
Appendix C MN-UT4500A
C–2
C.2 Maintenance Testing
The UT-4500-A Series Upconverters translate the input IF frequency from 52 to 88 MHz (or
optional 104 to 176 MHz) to an output RF frequency. For example, the RF output frequency of
the Model UT-4514-A is 14000 to 14500 MHz. The IF input level is -35 dBm (typical), and the RF
output level is +10 dBm at 1 dB compression.
To prepare for checkout, review the rack mounting information provided in Chapter 2.
INSTALLATION. Operations via the front panel (i.e., use of the menu system, keypad, and VFD)
are explained in detail in Chapter 5. FRONT PANEL OPERATION.
C.2.1 Test Point Samples
The IF output and RF input can be monitored at the RF Sample Test Points on the front panel. A
BNC female connector is provided for the IF sample and a Type ‘SMA’ female connector is
provided for the RF output. The RF sample output level is -20 dBc nominal, and the IF sample
input level is -20 dBc nominal.
C.2.2 Troubleshooting
Upconverter operating problems can be identified by first observing the LED status indicators on
the front panel. When a fault condition is indicated, or and marginal performance tolerance
condition exists, the specific fault or faults can be identified via the FAULTS menu branch,
accessible via front panel operation. See Sect. 5.3.3 FAULTS in Chapter 5. FRONT PANEL
OPERATION for more information about viewing current or stored faults.
Upconverter operational status screens are available via the MONITOR menu branch. See Sect.
5.3.2 MONITOR in Chapter 5. FRONT PANEL OPERATION for more information.
C.2.3 Upconverter Faults
C.2.3.1 Prime Power
Check the dual fuses on the rear panel. The required prime power is 100 to 125 VAC, or 205 to
240 VAC @ 1 Amp. The optional DC prime power is -48 VDC.
C.2.3.2 DC Power Supply Module
15 VDC: A fault ("FT") indicates a voltage level exceeding ± 10% of the power supply voltage.
Check the output of the DC Power Supply Module. The typical current output level is 3.0 amps.
Check all connections to make sure they are secure. If the voltage exceeds ± 10%, or the power
supply module current is not approximately 3.0 amps, or the fault still exists, remove the power
supply and return it to Comtech EF Data for repair.
