Squelch Threshold
The squelch parameters can also be adjusted from
the computer by utilizing the Alignment Software.
Refer to the onboard help of the Alignment Software
Manual for details.
Tight SQL RSSI LEVEL (Wide)
r Select the band center frequency channel (CH2),
and with the RF signal generator turned to the
same frequency, set the generator for ±3.0 kHz
deviation with 1 kHz tone modulation, and set
the output level for 3.0 dBµ at the antenna jack.
Threshold NSQ LEVEL (Wide)
r Select the band center frequency channel (CH2),
and with the RF signal generator turned to the
same frequency, set the generator for ±3.0 kHz
deviation with 1 kHz tone modulation, and set
the output level for –8.0 dBµ at the antenna jack.
Tight SQL NSQ LEVEL (Wide)
r Select the band center frequency channel (CH2),
and with the RF signal generator turned to the
same frequency, set the generator for ±3.0 kHz
deviation with 1 kHz tone modulation, and set
the output level for 0 dBµ at the antenna jack.
Tight SQL RSSI LEVEL (Narrow)
r Select the band center frequency channel (CH5),
and with the RF signal generator turned to the
same frequency, set the generator for ±1.5 kHz
deviation with 1 kHz tone modulation, and set
the output level for 3.0 dBµ at the antenna jack.
Threshold NSQ LEVEL (Narrow)
r Select the band center frequency channel (CH5),
and with the RF signal generator turned to the
same frequency, set the generator for ±1.5 kHz
deviation with 1 kHz tone modulation, and set
the output level for –8.0 dBµ at the antenna jack.
Tight SQL NSQ LEVEL (Narrow)
r Select the band center frequency channel (CH5),
and with the RF signal generator turned to the
same frequency, set the generator for ±1.5 kHz
deviation with 1 kHz tone modulation, and set
the output level for 0 dBµ at the antenna jack.
r Adjust the squelch threshold level "Tight SQL
NSQ ( Narrow ) " such that the squelch just open at
this signal input level (the BUSY LED will turn
on).
