GPS RF General Testing
In radiated testing the CW level has to be higher because of the attenuation in
pad + cable + coupler. With a -20 dB pad, the signal level in the signal generator is
~ -110 dBm + cable attenuation + 20 dB + 18 dB. The CW analysis allows end-to-end
spectral purity to be assessed during manufacturing and development.
1. On the Phone Control dialog box, click the LOCAL button in the Phone State
area to put the phone into Local Mode.

2. Inject -110dBm tone at 1575.52 MHz at the GPS connector (X001) with a signal
generator or a call box.
