Ranger Commissioning Manual

Section 4 RF Testing

4.2.15.6 Linear Precorrection Procedure

Step

Procedure Description

Expected 

Observation

1

Connect the FSQ3 to the transmitter 
Mask filter output directional 
coupler forward port. The filter 
output must be connected to the 
dummy load. 
NOTE: The transmitter RF must be 
turned ON at the rated RF output 
power for at least four (4) hours to 
allow for the filter to warm up

.

2

Configure the transmitter to operate 
on air with Exciter A with 
precorrector settings to:
Non-Linear Precorrection = ADAPT
Linear Precorrection = BYPASS

3

Using Katts, transmit test pattern 
MER_p2.katts (provided by QC). Let 
the PID setting on the transmitter 
remain 16. Collect 10 sets of data 
after the bandpass filter using the 
FSQ test receiver, and compute the 
MER.

The MER should be 
at least 33dB for all 
active subcarriers

4

Perform the MER measurement 100 
times at the MediaFLO channel filter 
assembly output directional coupler 
forward port. The MER measurement 
procedure also outputs the residual 
group delay. Group delay data may 
be averaged with 16 sliding averages 
in post processing procedure (using 
excel).

Residual Group 
Delay is less than 
1usecs over 
Fc+2.71MHz or Fc-
2.71MHz in all the 
100 MER 
measurements.

5

Transmitter turned ON with linear 
and non-linear precorrection 
performed and turned ON with 
Exciter A 
Measure the amplitude response.

Amplitude variations 
within Fc±2.71MHz 
is less than ±0.5dB in 
all the 100 MER 
measurements.

6

Repeat steps 3-5 with Exciter B on 
air.

Results should be 
consistent with those 
from steps 3-5.
