ADS1294R: Noisy data in V1 in ADS1294R

Part Number: ADS1294R


Tool/software:

Hi,

Channel 1 - RESPIRATION

Channel 2 - ECG signals (LA-RA)

Channel 3 - ECG signals (LL-RA)

Channel 4 - ECG  signals (V1 -WCT)

We are able to get Channel 2 &3 signals.

But Channel 4 seems to be noisy.

Register settings done

Config1 0x66

Config2 0x00

Config3 0xc0

Config4 0x22

LOFF 0x03

CH1SET 0X00

CH2SET 0X40

CH3SET 0X40

CH4SET 0X40

WCT1 0x0A

WCT2 0xE3

Do we need to change the register settings?

What register setting to be done to use channel 1 as respiration modulator and Channel 4 as V1?
