channel of PORT 1 just has simple 2 band preselector, whose range is below
500MHz and above 500MHz, respectively.
Port 1 is mainly used as an
and the amplitude is higher.
As for 18.6GHz model, the left port is also used to connect GPS antenna.
2.1.2 PORT 2 (Right Port)
Port 2 supports 9kHz-10.8/18.6GHz range input, 80MHz - 6GHz output.
Port 2 is mainly used as a
10.8GHz model, there are 6 bands below the 6GHz and the last band within 6-
10.8GHz. As for 18.6GHz model, 7 bands below 6GHz and 6-18.6GHz adopts
tracking preselector. The output RF signals from port 2 is relatively weaker. It
can effectively suppress the FM broadcast interference.
15ghz, due to the lack of fine preselector, user should pay attention to the
image interference. The center frequency can be adjusted to observe the
moving direction of the spectral line and determine whether it is mirror
interference.)
Both ports have 30dB attenuator(10dB step) and 40dB variable gain
preamplifier(20dB step). The total gain of front end is 70dB, and the
output/input signal strength can be adjusted precisely.
