AFE4300: AFE4300 calibration routine

AFE4300: AFE4300 calibration routine

Part Number: AFE4300

Hi,

I am now doing the calibration for my I/Q mode measurement on AFE4300.

The following questions that I just wondered.

1. Is the DAC frequency should be the same as ADC?  (8K<->8K, 16K<->16K....)?

2. Is it possible to measure the I and Q with AFE4300 Device GUI at the same time?

Thanks for any reply.

BRs

    Hi Gary,

    Few answers.
    1) No, DAC's frequency will not be same as ADC. ADC will run at 250KHz where as DAC's frequency is programmable. Refer to BCM_DAC_FREQ in datasheet for further reference.
    2) No, you have to switch the between I and Q channel sequentially.
