Appendix A:Merlin II Clock Calibration
The Merlin II system comes with a factory-tuned oscillator used to
generated the internal clock. This clock is used for tracking the Bluetooth
traffic and has to be kept calibrated.
The following is a detailed procedure for measuring and calibrating the
oscillator.
Please do not try to do this calibration without the proper tools. Tempering
with the clock calibration might void the warranty on Merlin II.
Tools needed for the calibration:
• The Merlin II system that you want to calibrate.
• Breakout board
• Mini DIN cable to connect the breakout board to the Merlin II
• Frequency counter
• BNC cable to connect the counter to the breakout board.
Steps prior to the procedure
Step 1 Make sure the breakout board is connected to the analyzer.
Step 2 Connect a frequency counter you want to use for the frequency
measurement to the 'EXT OUT' BNC connector on the breakout
board through a BNC cable. The frequency counter must be able to
count frequencies up to 30MHz.
Step 3 Verify that the analyzer is powered and connected to the host
machine.
1.1 Procedure:
To be able to access the clock calibration functionality in the
application, you should run the Merlin II application from a
command line with a -CLK argument:
Step 1 Select Start > Run.
