N2420B Operating Manual:Glossary 5
Once the equipment is deployed, you can verify the signal strength by
entering into Command Mode and reading Register S123. This register
provides the average signal strength in dBm. The minimum strength for
communication is roughly -108dBm. For consistent reliable
communication, you should try to deploy the equipment such that signal
strength exceeds -95dBm.
3.2 Antennas and Cabling
This section describes the recommended procedure for installing cabling
and antennas for use with the N2420B module.
3.2.1 Internal Cabling
The most common method for installing the module is to run a cable from
the module’s MCX connector to a reverse TNC bulkhead connector on the
chassis of the equipment as shown in Figure 3. This cable can be purchased
from Microhard Systems.
Figure 3 Suggested Internal Cabling
Cable losses are negligible for the short piece used within the chassis.
Additional losses up to 0.5 dB may be present in the MCX and Reverse
TNC connections.
