Set command

The set command controls the RF receiver.



The set command parameters and their defined values are the following:

0 – RX.
1 – ON.
0 – OFF.
Note: Always send OFF <operation> before sending another ON <operation>.
3GPP band number. Use 24 for Global Navigation Satellite System (GNSS) reception.
DECT NR+ bands 1, 2, 9, and 22 are supported when <param3> is 10. See ETSI TS 103 636-2 V1.4.1 Table 5.2-1.
Frequency 100 kHz.
Valid range 6000–22000 (corresponds to 600.0 MHz–2200.0 MHz).
In DECT NR+, the valid range is 18800–19300 (corresponds to 1880.0 MHz–1930.0 MHz) depending on the DECT NR+ band selected in <param0>.
Note: If Carrier Wave (CW) is used, an offset of about 45 kHz for Narrowband Internet of Things (NB-IoT) and 300 kHz for LTE-M is recommended.
RX signal power at the SiP antenna port.
Valid range from −127 dBm to −25 dBm.
System mode.
0 – NB-IoT.
1 – LTE-M.
10 – DECT NR+.

Response syntax when <operation> is ON:

%XRFTEST: <antenna_power>, <headroom>

The response parameter and its defined value are the following:

Measured power at the SiP antenna port in q8 dBm. q8 means that dividing the result by 28 = 256 gives dBm.
Time domain signal headroom in dBFullScale.
Expected value is −15 dBFS or −16 dBFS if the signal level in generator corresponds to the level given in <param2>.

The following command example enables the RF receiver for Band 1, 2140.0 MHz, −65 dBm, NB-IoT mode:

%XRFTEST: -17002, -16
Note: −17002/256 = −66.4 dBm

The following command example disables the RF receiver:
