Reader RF Power
During initial installation, the reader must be properly configured to use the correct RF
power to comply with FCC or other regional regulations. DO NOT increase the power
beyond this level.
The Sargas supports separate read and write power level which are command
adjustable via the MercuryAPI. Power levels must be between:
– Minimum RF Power = 0 dBm
– Maximum RF Power = +30.0 dBm
Power Settings for Authorized Antennas and Cables
This device has been designed to operate with the antennas listed in
Authorized
Antennas
list using the cables in the
Authorized Cables
list. For any combination of
antenna and cable the maximum RF power is determined from antenna gain (Max Linear
Gain value from antenna list) and antenna cable loss (Insertion Loss value from cable list)
using the formula:
Pmax = 36 dBm - Antenna Gain + Cable Loss
For more information about setting the RF power, refer to
