4 RU SSPA Chassis Operations Manual

For changes that require more than 5 dBm of level adjustments, ALC performs coarse
adjustment first (output signal will be adjusted within ±2 dBm range) and then perform
fine adjustment to get the output signal to within a ±0.3 dBm range from the set value.
For changes less than 5 dBm, the ALC circuit will not use coarse adjustment at all.
Overall time lag will be cumulative from the coarse and fine adjustment procedures.

Coarse adjustment speed is approximately 5 dBm/sec. Fine adjustment speed is
approximately 0.5 dBm/sec.
