Modulator
changes the following parameters depending on the transmission standard (DVB-T in
this example)
10
Bandwidth
6M, 7M or 8M
11
Constellation
QPSK, 16 QAM or 64 QAM
12
FFT
2k, 4K or 8K
13
Guard interval
1/32, 1/16, 1/8 or 1/4
14
FEC
1/2, 2/3, 3/4, 5/6 or 7/8
Tip
Different bandwidth, constellation, guard interval and code rate (FEC) combinations produce different
output data rates.
15
RF Frequency
30 – 1000 MHz
16
RF Level
70 – 90 dBμV
17
RF On
switches RF on or off
18
Bit rate
current modulation rate and maximum bitrate (display only)
19
Change Modulation
adapts the modulation to the transmission standard (DVB-C, DVB-T or ISDB-T) of the
TV set that is being used to receive the RF signal
The device must be rebooted once the transmission standard has been changed.
