PT100 is a DVB-T modulator based on IT9507+AD8345 chips - http://www.hides.com.tw/product_pt100_eng.html
!!! available from version from 2021.08.09
There are 4 modulators on the board, with the characteristics:
Frequency range 50~950MHz step size 1KHz
Modulation - 64QAM/16QAM/QPSK
Signal/Noise: 45dB
RF Output Level -8 dBm (100 dBuV)
Setup:
Find the modulators number using the command:
find "/dev" -name "it950x*"In the output of the command, we will get the numbers of the modulators:
root@dvb:~# find "/dev" -name "it950x*"
/dev/usb-it950x3
/dev/usb-it950x2
/dev/usb-it950x1
/dev/usb-it950x0it950x0 - where 0 is the modulator number
Let's set up Astra:
An MPTS stream must be sent to the modulator
In the output setting, we specify the type it950x: it950x://#adapter=0 (0 - modulator number)
Additionally - there is an option gain=x (the percentage value can be in the range from 0 to 100) - this option controls the signal level.
Astra receives data on the frequency and type of modulation from the completed NIT table in mpts.
