AWR1443: Idle time and ramp End time are different from configuration compared with measurement.

Part Number: AWR1443

Hi,

 We use VNA to measure the chirp signal, and find out the measure results are difference from the mmWave Radar Studio configuration. Is this configuration problem?

 Please see below the problematic portion with measured plots.

Q1: Idle time measurement result 68us is much longer than configuration setting of 3us.

Q2: Ramp end time measurement is shorter (82us) than expected 148us.

Q3: Due to ramp end time is shorter, the real Bandwidth measured (~240MHz) is also smaller than configuration ~435MHz.

 

The Radar Studio setting:

 

 

The VNA result:
