AWR1642: how to take measurement at fixed frequency by SDK1.1, not RadarStudio?

Part Number: AWR1642


hi,

In SDK 1.1, in my mind, there are 2 ways to implement fixed frequency TX/RX:

1) configure to be DfeOutputMode to 1 (chirp/frame), and set slope rate is 0.

2) configure to continuous mode

Are they both working?

Further, 

If EVM is configured to be ChannelCfg 15 0 0, does it mean no TX power, but only RX processing?

Thanks!

    Hello Wang,

    For continuous mode, the "dfeDataOutputMode : 2 " . You should not be using "dfeDataOutputMode :1" and set slope to 0.

    Can you also please mention the configuration you are referring in the SDK ?

    Sorry, maybe I made some confusion.

    What I mean is to get fixed frequency has 2 methods:
    method 1) using frame/chirp mode and take slope rate to 0. This means TX/RX works as common radar, but no frequency slope rate, and RF will be at a fixed frequency, which could help to take some measurement, such as EIRP or TX power.

    method 2) using DfeOutputMode to 2 as continuous mode, which will be naturally a fixed frequency.


    Further question is, if i set channelCfg 15 0 0, does it mean no TX, only 4 RX channel on.

    Thanks!
