4. Pressing “Num Lock” several times will step trough available modes in the basic setup:<br />
Figure 4 – CES Stand Alone test modes<br />
The modes will start at the beginning after “Test mode off”<br />
Note: Make sure the keyboard layout on the PC is set to “English”. Else, parts of the text might be<br />
unreadable.<br />
The different modes:<br />
TX Un-modulated carrier: Measure output power and harmonics<br />
TX Modulated carrier: Modulated with a PN9 sequence, to do bandwidth measurements.<br />
RX:<br />
To measure LO leakage in RX mode.<br />
TX Un-modulated sweep: Sweeps the carrier from ch 02 to ch 81. Max hold on spectrum<br />
analyzer to measure the whole band.<br />
RX sweep: Sweeps the receiver from ch 02 to ch 81<br />
All TX modes are with 0dBm output power.<br />
Note: The un-modulated carrier is slightly modulated by the preamble, so the carrier does not look<br />
completely clean. This mode is intended for output power measurements only.<br />
The exact same setup can be used with the <strong>nRF24LU1</strong> USB Dongle.<br />
