AFC measurement

Syntax:

%XRFTEST=<test>,<operation>,<param0>,<param1>,<param2>

The AFC measurement command parameters and their defined values are the following:

<test>

4 – AFC

<operation>

1 – ON (measure)

Note: OFF <operation> is not needed due to automatic stop. Mode is always LTE-M. The stored value is reset when the device is booted.

<param0>

3GPP band number

<param1>

Frequency (100 kHz)

<param2>

RX signal power at the System in Package (SiP) antenna port in dBm

Response syntax:

%XRFTEST: <AFC_error_value_Hz>,<AFC_error_value_Q30>

The response parameters and their defined values are the following:

<AFC_error_value_Hz>

Measured AFC error value in Hz format

<AFC_error_value_Q30>v1.2.x≥1pti_v1.1.x≥1

Measured AFC error value in relative signed Q30 format

The following command example measures the AFC error value for band 1, 2140.0 MHz, -40 dBm:

AT%XRFTEST=4,1,1,21400,-40 
%XRFTEST:349,175
