How to enable 2 RX channel of adrv9009 base on adrv9009-iiostream.c?

On the adrv9009-ZU11EG Noticing discontinuities/saturation on the data on this set up when writing to disk vs when only one channel is enabled :( I have cma = 1024M set and also using tmpfs for optimal write speeds.

See those artifacts in the time series around 0.01s?

Results when only one channel is enabled. Notice the amplitude in the time series dosent spike up and I ploted a few more miliseconds.

Do you have a perfectly clean environment? Or for example ground the inputs and set the gain to 0?

I've seen similar data from random Wi-Fi or LTE traffic.

Hey Trav, How about code to enable RX1A (I and Q) from adrv9009-phy and 

RX1B (I and Q) from adrv9009-phy-b from ADRV9009ZU11EG. This is what I've tried.

I'm noticing that I'm configuring the frequency for both devices ( out_altvoltage0_TRX_LO_frequency file is being updated for both adrv9009-phy and adrv9009-phy-b)

Are you setting out_altvoltage0_TRX_LO_frequency with separate iio_devices? Your code snippets do not reference these calls.

Yes frequency is configured before these code snippets.

wanted to see if I’m enabling the channels correctly.

thanks 

Child id should be 1 not 2 for secondary RX channels.

Im trying to enable adrv9009-phy's primary RX channel and adrv9009-phy-b's primary RX channel.

I.e. the RX1 channel for each ADC, No secondary RX channels.

Then index 0 and 2 are fine.
