AWR1642: Calibration function for AWR1642

Masa_0301
Intellectual 350 points
Part Number: AWR1642

Hi All

I have checked the following documentation regarding calibration function and I want to know the some specification.

http://www.ti.com/lit/an/spracf4/spracf4.pdf

Could you let me know following specifications

①Calibration resolution

②Target calibration range →Less than ~db etc...

　Looking at the figure 2, it seems that it is about 0.5 dB on one side

③PGA resolution  (worst case)

Best regards,

Masa0301

    Hi,

    Additional information regarding calibration can be found in the Radar Interface Control Document

    C:\ti\mmwave_dfp_01_02_00_01\docs\AWR1xxx_Radar_Interface_Control.pdf

    This document includes the APIs that enable/disable these calibrations

    We will check with our design team and will get back to you in a few days.

    thank you

    Cesar

    Hi,

    Sorry for the delay

    1) Calibration Resolution

    Please see in the application report section 4 Scheduling of Periodic Runtime Calibration and Monitoring

    2) Figure 2 only shows the results of calibration that was performed at a certian periodicity. I have talked to the person who wrote the appnote and the periodicity for the data displayed in figure 2 is not available. This is only the result. There is not a notion of target calibration range

    3) Regarding additional information, please consult the AWR1xx Radar Interface Control document included in the DFP release

    Thank you

    Cesar
