RF Sample: Output Sample from Combiner thru Control
Board. In a CU500, the sample level is approximately 70dB
down from the output power level of the tray.
50Ω
Refer to Figures 3 and 4, and Tables 2 and 3 for detailed information on the jacks and
connectors. Connect the On Channel RF Input (BRD), –78 to –8 dBm, or the SMPTE-310
Input (BTD), to the 50Ω BNC input jack J1, located on the rear panel of the CU5 thru
CU125 systems and the driver trays for the CU250 and higher power systems.
If used, connect the external 10 MHz reference input to the 50Ω BNC 10 MHz input jack
J6 located on the rear panel of the CU5 thru CU125 systems and the drivers for the
CU250 and higher power systems. If used, connect the external 1 PPS reference input
to the 50Ω BNC 1 PPS input jack J7 located on the rear panel of the CU5 thru CU125
systems and the drivers for the CU250 and higher power systems.
The digital RF ON Channel output of the CU5 thru CU125 systems and the driver trays is
at J9 the 50Ω “N” connector RF output jack located on the rear panel. In CU5 thru
CU125 systems, the output of the tray at J9 connects to the digital mask filter and then
to the antenna for your system. In CU250 and higher power systems, the output of the
driver tray at J9 is connected to J1 the 50 Ohm “N” connector RF input jack located on
the rear panel of the 250 Watt, 500 Watt amplifier tray or to a splitter in multiple
amplifier systems. Check that the system power metering interface cable is connected
from J11 the 9 position “D” connector located on the rear panel of the driver tray to J4
the 9 position “D” connector located on the rear panel of the 250 Watt or 500 Watt
amplifier tray. This cable provides the control, status and operating parameters of the
amplifier tray to the driver tray. The digital RF ON Channel output of the amplifier tray
is at J2 the 50Ω “7/16” (1.1cm) Din connector RF output jack located on the rear panel
that connects directly to the low pass filter, the digital mask filter and then to the
antenna for your system in single amplifier systems or to a combiner and then the low
pass filter, the digital mask filter and finally to the antenna in multiple amplifier systems.
