IWR1443BOOST: IWR1443 Can the IF signal be used to measure the waveform through the oscillograph

Hi, there:

Can you explain in more detail about your first question?  What you are trying to measure?  What will be the system setup to do that?

For your second question, yes, iwr1443 has two stages of analog highpass filter, and the corner frequency of the high pass filter can be programmed through profile configuration inside radar studio or profileCfg in SDK demo.  After sigma-delta ADC, there are stages of low pass filter before each down sampling stage, but they are not programmable.

For the two stage of high pass filter setting, you can search "hpfCornerFreq1" and "hpfCornerFreq2" at SDK doxygen documentation below:

I hope that the waveform of IF signal can be measured by oscilloscope.

The IF signal can be output at the chip pin for testing.

What is the order and cut-off frequency of low-pass filter?

Does iwr1443 have low power consumption mode? Can 4-20mA power supply support??

The low pass filter order is not available.  But you can find following information about the filter performance. the The filtering performed by the digital baseband chain is targeted to provide: • Less than ±0.5 dB pass-band ripple/droop, and • Better than 60 dB anti-aliasing attenuation for any frequency that can alias back into the pass-band.

You will need to submit a different e2e ticket on the Low power mode.

My impression is no, but I will check with our hardware expert and get back to you later.

Best,
