12 dB SINAD
(Wide band measurement
method: no audio filtering)
Using a 1KHz tone, set TX
deviation to ±1.5 kHz for a
12.5KHz channel,
±3.0 kHz for a 25KHz
channel and ±6.0 kHz for a
50KHz channel..
Better than -109 dBm for
12.5KHz channel, -110 dBm for
25KHz channel and -108 dBm
for 50 KHz cha
nnel usin
g a 2ft
RG-223 coax cable.
- Backplane corresponding
to the receiver being veri-
fied: J18 pin 1 for RX1 or
J19 pin1 for RX2 (see
Figure 425). GND pin
available at TP33
- Service monitor (IFR) set
to SINAD
- IFR IF filter set to MID
position or 30 kHz wide
filter.
If the 12 dB SINAD is
found to be out-of-
specs, check for bad
connections, damaged
coax cable, etc.
If not OK, contact
CalAmp support.

Receiver distortion
(Wide band measurement
method: no audio filtering)
Set service monitor RF Gen
output to –70 dBm.
Using a 1KHz tone, set TX
deviation to ±1.5 kHz for a
12.5KHz channel,
±3.0 kHz for a 25KHz chan-
nel and ±6.0 kHz for a
50KHz channel.

RSSI
Apply to each receiver input
the following RF level:
UHF, 700 & 800 MHz:
-80dBm, unmodulated. -Æ
-110dBm, unmodulated. -Æ
UHF, 700 & 800 MHz:
2.75 VDC (±0.2VDC)
1.45 VDC (±0.2VDC)
BSC2 must be connected to
the radio during the
measurements
- Backplane corresponding
to the receiver being veri-
fied: J18 pin 4 for RSSI1
or J19 pin 4 for RSSI2
(see Figure 4). GND pin
