2.1.4 Sencore DSL757
The Sencore DSL757 Digital Director (www.sencore.com) is a dedicated test device
to meter cable signal levels. One of its basic modes is to display on its LCD screen
the received signal level.
Connect a temporary 2-way splitter to the Subscriber Transceiver and then connect
the Sencore meter to the splitter.. Align the Transceiver by peaking the signal on the
display.
Remove the splitter and connect the modem’s cable to the transceiver. Tape the F-
connector to protect it from the weather.
2.1.5 Spectrum Analyzer
Connect the spectrum analyzer, such as Anritsu MS2711B of Figure 2-6, via a
temporary 2-way splitter at the transducer.
Figure 2-6: Anritsu MS2711 portable spectrum analyzers.
Adjust the spectrum analyzer to display the downstream IF signal from the
Subscriber Transceiver (which will be between 425 and 550 MHz). Reduce the
frequency span and adjust the amplitude to achieve a trace similar to the one in
Figure 2-7.
