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 ƒcenter –
2.4MHz to ƒcenter +2.4MHz shall not
exceed +/-200nS relative to the delay at
ƒcenter
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 compensate +/-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.
