QoS
(P25 channels
only) Displays information about the quality of service
(received signal strength (RSSI) with an indication of
digital voice quality). Also displays the channel
status (CNV, TCH, CCH
1
) and the mode (PH1 or
PH2
2
).
RSSI Displays the received signal strength (RSSI) of the
current channel.
Rx Tone Receives a 1011 Hz or 1031 Hz tone and displays
the received signal strength (RSSI) and the bit error
rate (BER) of the received signal. Also displays the
channel status (CNV, TCH, CCH
1
) and the mode
(PH1 or PH2
2
). On a P25 conventional channel, the
user can select whether to receive a 1011 Hz (Phase
1) or 1031 Hz (Phase 2) tone. On a P25 trunked
channel, the network selects whether 1011 Hz or
1031 Hz is used.
Site display Shows the channel number, signal strength and
system-identity code (SYSCODE) for the currently
registered trunked site.
Site measure Lists the current trunked site (indicated with an
asterisk) and up to six detected adjacent sites, with
received signal strength (RSSI) information.
Tone test Generates an audible tone for the duration of the
test.
Tx Tone Transmits a tone of 1011 Hz or 1031 Hz on the
current P25 channel.
Tx Tone Cal Transmits a 1011 Hz or 1031 Hz tone on the current
channel with a bit error rate (BER) of 5%.
Tx power test Displays hardware-related information while the
radio is transmitting. Information includes the final
PA current (in mA)
1. CNV = conventional, TCH = traffic channel, CCH = control channel
2. ANA = analog, PH1 = P25 Phase 1, PH2 = P25 Phase 2
