2.3.2 Test Points / Power Indicator
ON
This is an LED indication. When lit GREEN, the LYNX.sc is powered.
The LYNX.sc radio products do not have an on/off switch.
GND
This is a test point referenced to chassis ground. This is used in conjunction with the
next two test points to measure voltages related to radio performance.
RSL
This is a test point which relates to the Received Signal Level (RSL). A voltage can
be measured with a voltmeter (using the GND test point for reference) which
corresponds to the actual power level of the incoming received signal. While the
DISPLAY FAR END button is pressed, this RSL voltage corresponds to the RSL of
the far-end radio. These measurements are used during installation, maintenance
and troubleshooting.
LOCAL
TX PWR
This is a test point which corresponds to the output transmit power of the radio. A
voltage can be measured with a voltmeter (using the GND test point for reference)
which corresponds to the actual power level of the outgoing signal. This
measurement is used during installation, maintenance and troubleshooting
. This voltage only applies to the near-end and does not allow measurement
of the far-end output transmit power, even when the DISPLAY FAR END
button is pressed.
There is a receptacle on the front panel to the right of the LOCAL TX PWR test point
which is an installation adjustment allowing the output transmit power to be
increased or decreased within the radio's specified limits. Using a small screwdriver,
this adjustment is used to set the output power of the transmitter, in accordance to
the path planning.
The LYNX.sc systems requires professional installation. Transmitted output
power limits may apply when using this radio. Consult FCC, IC, ETSI
Glenayre Western Multiplex or other regulatory authorities for limits which
may apply. See Section 3.13.1 for details on setting output power.
