ALPA – AUTO LEVELING POWER AMPLIFIER
The Auto Leveling RF Power Amplifier can be used with the STx or another nominal 200 mW DVB-T source to boost the output power level to 2 Watts. It features proprietary auto leveling circuit which maintains the RF output power constant at 2 Watts. The use of industry standard interfaces makes this product compatible with multiple vendors’ equipment. The performance is suited for today’s digital modulation techniques, including COFDM, QPSK, 16QAM, 64QAM, and VSB.
The RF power control switch modes are: standby, low power (21 dBm), medium power (27 dBm), and high power (33 dBm). At a glance the user will see the current state of the unit.
For users that have remote power needs, an optional bias-T can be added. All the units feature a RS232 interface for remote mode setting, alarm reporting and status monitoring.
