TIDM-1000: To operate TIDM-1000 at input line frequency 400Hz

Hi,

I want to operate the TIDM-1000 board at 400 Hz input line frequency.

In POWER_MEAS_SINE_ANALYZER_config function:

Existing -

    POWER_MEAS_SINE_ANALYZER_config(&VIENNA_sine_mains1,
                                    VIENNA_ISR_10KHZ_FREQUENCY_HZ,
                                    (float32_t)0.08,
                                    (float32_t)40,
                                    (float32_t)110);

Changes -

    POWER_MEAS_SINE_ANALYZER_config(&VIENNA_sine_mains1,
                                    VIENNA_ISR_10KHZ_FREQUENCY_HZ,
                                    (float32_t)0.08,
                                    (float32_t)40,
                                    (float32_t)450);

1.Will the module work with above changes?

2.Shall we increase the ISR freq (VIENNA_ISR_10KHZ_FREQUENCY_HZ) to 20KHz or more to get appropriate number of samples from input line.

With regards,

Selvam
