MHz
4. UHF input power –18dBm ±3dB
5. UHF input waveform COFDM
DVB-H
6. ALC – ON, AGC – ON
7. 7. Linearization – ON
Out of band Intermodulation prior to
channel filter
Per spectral mask defined as:
Lower
Channel edge falls between 1670-
1670.122875 MHz
Shoulder at 1669.822975 MHz and
lower must bed -32 dBc
Upper
Channel edge falls between
1674.877125-1675 MHz
Shoulder at 1675.177125 MHz and
above must bed -32 dBc
TX input has to exceed FCC spectral
mask definition, if OEM exciter used,
in order for TX compliance shoulder
level typically should be better than
50dB at breakpoint w/ minimum of 8db
non-linear correction capability.
1. Thermal power sensor is
recommended to verify average
output power. Emissions
measured with spectrum analyzer
or VSA RBW=30kHz VBW=
100Hz
2. One modulated carrier
3. UHF input frequency 670 – 675
MHz
4. UHF input power –18dBm ±3dB
5. UHF input waveform COFDM
DVB-H
6. ALC – ON, AGC – ON
7. Linearization – ON
Inband Intermodulation
Intermodulation products shall not
exceed –30dB when comparing portion
of the mean power spectral density of
the wanted COFDM signal relative to
the same portion when “n”-number of
carriers are switched off. Sampled
bandwidth not to exceed bandwidth of
carriers removed.
Modulator must have facility to switch
off a block of carriers within the
COFDM signal and have better than –
33dB IM when same test is conducted
at input.

Transmitter Frequency Response,
fixed 5 MHz channel
Relative to the level at ƒcenter shall not
deviate by more than +/-0.5dB across
the frequency range ƒcenter –2.4MHz
to ƒcenter +2.4MHz.
Frequency response is measured at
the output of the channel filter. Test is
done using spectrum analyzer with
modulated input waveform and:
1. UHF input frequency 670 – 675
