Parameter Specification Test Conditions/ Notes
MHz
2. UHF input power –18dBm ±3dB
3. UHF input waveform COFDM
DVB-H
4. ALC – ON, AGC – ON (if
spectrum analyzer or VSA is
used; both OFF if network
analyzer method is used)
5.
Linearization – ON
Transmitter Group Delay, fixed
channel, 5 MHz wide
Over the frequency range ƒ center –
2.4MHz to ƒ 2.4MHz shall not
/-200nS relative to the delay at
ƒ center
Group Delay is measured at the output
of the channel filter. Test is done using
network analyzer broadband detection
from UHF input to channel filter output.
Modulator must comp/-100 ns
of delay and:
1.
UHF input frequency 670 – 675
MHz
2. UHF input power –18dBm ±3dB
3. IF input waveform COFDM DVB-
H
4. ALC – OFF, AGC – OFF
5. Linearization – ON
Transmitter Carrier to Noise (C/N)
t
55 dB
C/N is measured at the transmitter
output (no channel filter).
RF Output power, 5 MHz channel,
measurement conditions
1.
UHF input frequency 670 – 675
MHz
2. UHF input power –18dBm ±3dB
3. IF input waveform COFDM DVB-
H
4. ALC – OFF, AGC – OFF
5. Linearization – ON
Thermal Noise Power is measured at
5MHz BW at the channel center
frequency.
Measurement is done with Spectrum
Analyzer or VSA using PSD.
Spurious Products
(Undesired signal power 2 dB
higher than the nominal PSD of the
adjacent spectral regions that is
harmonically related to
unmodulated carrier)
d
-60 dBc
Relative to nominal modulated power
measured @ 100 kHz RBW at the
channel filter output.
