Spurious response
J3E
: 60 dB or more
F1B
: Symbol error rate of 1% or better at a wanted
signal level of 10 uV and an unwanted signal
level of 31.6 mV separated by 750 Hz
Blocking/Desensitization
J3E
: When an unwanted signal level separated by 3
kHz is added to the wanted signal level of 10 uV,
the unwanted signal input voltage suppressing
output of the wanted signal by 3 dB is 10 mV or
more.
F1B
: Symbol error rate of 1% or better at a wanted
signal level of 10 uV and an unwanted signal
level of 1 mV separated by 500 Hz
Overall distortion and noise
When an input signal level of 30 uV is applied, the ratio
between low-frequency output 1000 Hz and unwanted
components contained in that output is 30 dB or more.
