Automatic Gain Control and Manual Gain Control
The gain setting of the receiver’s low noise amplifier (LNA) is adjustable.
By default, the 250 Series is factory-configured to use its internal automatic gain control (AGC) circuit to manage receiver sensitivity. Reducing the gain increases the linearity of the receiver, but reduces maximum sensitivity; increasing the gain does the opposite. Generally speaking, higher linearity (increased third order input intercept point, IIP3) gives improved
performance in high-interference environments; high gain yields better performance in low-interference environments.
