5.3.1 Gain Setup
5.3.1.1 DL Gain Setup
32. From the Function Explorer Tree on the left select
tHost™
unit. The
tHost™
main page will appear.
Note: tHost™ maximum input level with 0dB DL attenuation setting is -7 dBm. Absolute maximum
average power at DL input is 0 dBm, but DL attenuator shall be set to 1 to 7 dB (for levels from -6
to 0 dBm) to prevent saturation (overflow) of digital section. Hence, to achieve maximum average
power of 43 dBm, DL input signal range shall be between -7 dBm and 0 dBm of average power,
with tHost™ attenuator setting from 0 to 7 dB. Unit is designed for PAR of < 12 dB. An analog
protection circuit is enabled if DL input average power is higher than 0 dBm (by adding 30 dB of
attenuation).
33. Read “DL Input Power” (Pin) at a particular band, and calculate the DL Gain (G
DL)
you want to set (G
DL
=
Pout - Pin). Calculate initial DL attenuator value as Max. Gain (50 dB) – G
DL
(e.g. if Pin = -5 dBm, and
Pout=43 dBm, then G
DL
= 48 dB, and ATT
DL
= 2 dB)
34. Set DL Attenuator for particular band to calculated value. Click on “Set Parameters” button.
35. Repeat steps 33 and 34 until DL attenuation for all bands are set.
