The following table shows recommended test cases for conducted Global Positioning System (GPS) non-signaling mode.
| Mode | Test item | Test specification/ID | Band/Channel | Temp/Voltage | XRFTEST signal parameters | Expected result | Note |
|---|---|---|---|---|---|---|---|
| GPS RX | GPS sensitivity / CN0 (SNR) | NA | GPS | TYP/TYP | CW level -100 dBm + extLNA gain dBm1 | SNR >5 dB2 | Requires Carrier Wave (CW) signal generator |
The recommended signal level for GPS mode testing is -100 dBm. The %XRFTEST AT command uses the signal level at the nRF9160 GPS port as an input parameter for the RX gain setting. Therefore, the %XRFTEST signal power parameter needs to include the level increase from the external Low-Noise Amplifier (LNA).
The following figure shows the recommended GPS input signal level for GPS non-signaling mode testing.
