FAQ
Q: What is the digital interface of the 200 MHz amplifier?
A: The 200 MHz amplifier features a digital control input with two possible states:
- Floating (not connected): The amplifier operates at full gain, with no attenuation.
- Grounded: The amplifier is attenuated by 20 dB.
This digital interface allows simple on/off attenuation control via the logic level: leaving the input floating keeps the full signal, while grounding it reduces the output by 20 dB.
