Harmonics
(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.
Output Frequency
Single channel, factory selected at
1670-1675MHz, 5 MHz wide
Output Spectrum Orientation Non-Inverted
Output Impedance Output Return
Loss
50 : 15 dB
Measurement of the output return loss
at the N connector of transmitter with
all amplifiers connected and turned on.
From 1670-1675MHz
RF Output Regulation
dr 0.3 dB
Measured at transmitter output at
nominal output power and:
1. UHF input frequency 670 – 675
MHz
2. UHF input power –18dBm ±3dB
3. UHF input waveform COFDM
DVB-H
4. ALC – ON, AGC – ON
5. Linearization – ON
RF output regulation is defined as
regulation vs. temperature.
Hum and Noise
d -60 dBc
Test of power supply DC output under
full load measurement by ratio of RMS
hum or noise to the corresponding DC
voltage
MER
t 30 dB
Measurement at nominal output power
COFDM DVB-H, Measured at channel
filter output
MER = 20 log (EVM/100)
Error Vector Magnitude (EVM)
d 3.16%
Measurement at nominal output power
COFDM DVB-H, Measured at channel
filter output
Transmitter Output MUTE
