b. Marker: 5400 MHz
20. Note the RF power reading on the spectrum analyzer at the marker frequency and
correct it as discussed in step 12. This is the output level for the source transceiver at
the interfering frequency.
21. Terminate the stats command running on the Linux machine connected to the source
UWB transceiver. Then run the following command on the PC connected to the source
transceiver:
./mode B
22. Turn on the signal generator and wait for it to warm up the length of time specified by the
manufacturer.
23. Change the spectrum analyzer settings as follows:
a. Sweep range: 800 MHz to1000 MHz
b. Marker: 900 MHz
24. Set the signal generator as follows:
a. Frequency: 900 MHz
b. Output level: -100 dBm (or the minimum for the instrument)
c. Sweep: Off
d. Modulation: None
e. Pulse generation: Off
25. Run the following commands on the Linux PC connected to the UWB source transceiver:
./mode B
./config 1 114 NONE 16k 0
./mode PT
./stats FRAM MACAddress
26. Increase the output level on the signal generator until an FER of 10% (1X10
-1
) is
reported on the destination transceiver.
27. Terminate the stats command running on the Linux machine connected to the source
UWB transceiver. Then run the following command on the PC connected to the source
transceiver:
./mode B
28. Note the RF power reading on the spectrum analyzer at the marker frequency and
correct it for the insertion loss of the two power splitters (approximately 14 dB) and the
fixed in-line attenuator (10 dB). This is the output level for an interfering source at the
frequency specified on the signal generator that is required to change the error rate from
2% to 10%.
29. Change the signal generator settings as follows:
a. Frequency: 1900 MHz
b. Output level: -100 dBm (or the minimum for the instrument)
30. Change the spectrum analyzer settings as follows:
a. Sweep range: 1800 MHz to 2000 MHz
b. Marker: 1900 MHz
31. Repeat steps 25 through 30 for this new interfering frequency (1900 MHz).
32. Change the signal generator settings as follows:
