15.2 kHz, 16.0k Hz.
Bandwidth Selection via Keypad Entry:
Upon entry, receiver automatically selects the closest filter in the menu of equal or
greater bandwidth.
Fast-Filters:
Fast Filters offer reduced signal latency and degraded shape factors to facilitate
reception of delay-critical digital modes.
Fast-Filter Selection:
All standard menu bandwidths up to 4 kHz are available as Fast Filters.
Fixed Bandwidths:
Bandwidth is fixed at 3.2 kHz in ISB mode.
Minimum available bandwidth is 600 Hz in FM mode, and 4 kHz in SAM mode.
Blocking on tune: <5% THD: -6 dBm input 30% AM 1 kHz.
Blocking off tune: 200 kHz offset. 15 dBm typ. 10 dBm mm for 3 dB desense.
Ultimate Rejection: Greater than 70 dB regardless of filter selected.
Group Delay: No more than .1 ms variation over passband of 300 Hz to 3050 Hz (Notch
OFF).
LO Phase noise: -120 dBc/Hz @ 20 kHz offset typical, -110 dBc/Hz max.
