FUNCTION
MUTE. TTL high enables output. Low mutes output.
Gain Control. Set JU2 to R4 for manual gain control. Set JU2
to R3 to allow feedforward AGC operation. The electrical
circuit board is always set for manual gain control.
Hysteresis. Leave open for (minimum) ±0.13dB hysteresis
between gain switch points. Connect 20kΩ to ground for
±0.3dB and short to GND for (maximum) ±0.65dB hysteresis.
