你好,有些问题让我很困惑。
- 在 mmWave Studio 对AWR1642进行设置时,其中 Frequency Slope(MHz/μs)可以设置为0吗?
- 可以设置成负值,使发射信号频率为slow up ramp吗?可以的话,最小范围是多少?

你好,有些问题让我很困惑。

frequency slope的取值范围为
Ramp slope frequency,
For 77GHz devices (76GHz to 81GHz):
1 LSB = (3.6e6 * 900) / 2^26 = 48.279 kHz/uS
Valid range: -2072 to 2072 (Max 100MHz/uS)
请看C:/ti/mmwave_sdk_03_05_00_04/packages/ti/control/mmwavelink/docs/doxygen/html/structrl_profile_cfg__t.html对freqSlopeConst参数的说明。
上面的取值范围为Valid range: -2072 to 2072 (Max 100MHz/uS),可以设为0或者负值。具体请看下面帖子里的解释。
