5-5 Transmit Tests
The following tests assume that all losses have been calibrated out of the
equipment (attenuators, power splitters, cables, ...)
“DUT” is the MIRAE wireless LAN card which should be tested, and “REF-SET”
is the MIRAE LAN card with known characteristics.
1. The RF switch should be set to allow use of Antenna 1(CR9 : value A0).
PTU test program – Alige BBP mode (Baseband Processor CR9 : A0) seting.
2. Set DUT as follows: Antenna 1 (Baseband Processor register CR9 : value A0),
Channel 1 select , Continuous 11Mb Transmit Mode select.
3. Set the Spectrum Analyzer as follows:
Center Frequency: 2412MHz (1st Channel)
Span: 66MHz , VID BW 10KHz , RES BW 300KHz
Reference Level: 0dBm
Leave all other Spectrum Analyzer settings at “Automatic”
4. Allow the transmitter to warm up for 1 minute before continuing.
5-5-1 Adjust and Measure Output Power for -30dBc first side lobe
1. Change the output power by Manual Tx Control (Baseband Processor register
CR31) in order to achieve the difference between the signal level at center
frequency and higher first side lobe of 30dBc (monitor at the Spectrum
Analyzer).
2. Record power output level from the Power Meter and Tx Power Measurement
(Baseband Processor register CR58), and the value of Manual Tx Control
(Baseband Processor register CR31).
4. Record values for the first and the second sidelobes. Second side lobe must be
-50dBc even if in the noise floor.
5-5-2 Carrier Frequency Accuracy Test (Channel 6)
1. Set the Spectrum Analyzer as follows:
Center Frequency: 2437MHz (6th channel),
Span: 10MHz
