The Clock reference box indicates what is providing the base station with a
reference frequency (from which it derives the channel frequencies).
Option Description
Internal The base station's own clock signal is the reference source.
External External equipment is providing the reference source via a BNC
connector at the rear of the reciter. The Service Kit must tell the
base station whether to expect 12.8 or 10 MHz (Configure >
Base Station > Miscellaneous).
The Reciter form (Monitor > Monitoring > Reciter) lets you monitor the
RSSI and SINAD of the received signal and the audio levels on the input and
output lines. Each level is displayed graphically as a gauge. The equivalent
numeric value appears under the gauge heading. If the value is red, it has
exceeded the maximum or fallen below the minimum that the gauge can
display.
The first box in the form displays the internal name of the reciter.
The Alarm status box indicates whether the reciter has an alarm. If the LED is
red, select Monitor > Alarms > Current Status to see which alarm is active.
The Received signal area displays the RSSI and SINAD levels. (If you want to
know the equivalent RSSI in microvolts, see
and dBm" on page 88). The SINAD is only an approximation, but it is
reasonably accurate if a receiver filter with a de-emphasised audio response is
selected.
The Input lines area displays the audio levels for the balanced and unbalanced
line inputs.
