Auto or manual control of input attenuator.
Audio and Modulation Filters
Lowpass Filters Four independently configurable Lowpass filters LP1, LP2, LP3,
LP4 that can be set to any frequency cut off point from 250 Hz
to 20 000 Hz (excluding the band 1001 to 2999 Hz).
50 kHz Lowpass (No filters applied).
750 µs de-emphasis.
Highpass Filters 50 Hz Highpass
300 Hz Highpass
Bandpass Filters Any combination of LP1, LP2, LP3, LP4 and the Highpass filters.
Amplitude Modulation
Frequency Range 100 kHz to 1.05 GHz
Modulation Frequency Range 10 Hz to 15 kHz
AM Depth Range 0 to 99% (manually tuned)
0 to 90% below 100 MHz
0 to 80% from 100 to 400 MHz
Peak hold facility
