Technical Specification
Parameter Requirement
Maximum RF Output power per channel
N=1: 60 dBmV
N=2: 56 dBmV (i.e. 59 dBmV total power)
N=3: 54 dBmV (i.e. 58.8 dBmV total power)
N=4: 52 dBmV (i.e. 58 dBmV total power)
RF Output power adjustment
8 dB range. All channels have the same
output power
Level adjustment steps 0.1 dB (monotonic)
Absolute RF Output power accuracy per
channel
±2 dB
RF Output level drift over temperature and
time relative to median at that channel
±1.0dB
Phase noise
1–10 kHz: <-33 dBc DSB
10–50 kHz: <-51 dBc DSB
50–3000 kHz: <-51 dBc DSB
Output Return loss
>14 dB 50-870 MHz
>10 dB 35-50 MHz and 870-1002 MHz
Adjacent channel (750 kHz from channel
block edge to Bsys MHz from channel
block edge)
6 MHz N=1/2/3/4: <-62/-60/-60/-60 dBc
8 MHz N=1/2/3: <-60.5/-59/-58.5 dBc
Next-adjacent channel (Bsys MHz from
channel block edge to 2Bsys MHz from
channel block edge)
6 MHz N=1/2/3/4: <-65/-64/-63.5/-63 dBc
8 MHz N=1/2/3: <-63.5/-63/-62.5 dBc
Third-adjacent channel (2Bsys MHz from
channel block edge to 3Bsys MHz from
channel block edge)
6 MHz N=1/2/3/4: <-73/-70/-67/-65 dBc
8 MHz N=1/2/3: <-71.5/-68.5/-65.5 dBc
Noise in other channels (47 MHz to 1000
MHz) Measured in each Bsys MHz channel
excluding: a) Desired channel(s). b) 1st,
2nd, and 3rd adjacent channels. c)
Channels coinciding with 2nd and 3rd
harmonics
6 MHz N=1/2/3/4: <-73/-70/-68/-67 dBc
8 MHz N=1/2/3: <-71.5/-68.5/-66.5 dBc
In each of 2N contiguous Bsys MHz
channels or in each of 3N contiguous Bsys
MHz channels coinciding with 2nd
harmonic and with 3rd harmonic
components respectively (up to 1000 MHz)
<-63 dBc
Where fc = carrier frequency, fw = individual channel bandwidth.
There is no support for individually setting the output power of each individual
channel in a group. There is no support for individually setting the modulation
parameters of each channel.
