Hi, what is the inband image frequency for nrf52832 ?The test house said it should be +4, is it correct? IXIT for RF IXIT Reference Identifier Sub-Identifier (Optional) Value "Units ( if applicable )" RF-PHY:P1:1 Inband Image frequency Low

Is the IXIT for RF of nrf52832 correct bellow? The test house said the value of inband image frequency should 4Mhz.

IXIT for RF
IXIT Reference	Identifier	Sub-Identifier (Optional)	Value	Units ( if applicable )
RF-PHY:P1:1	Inband Image frequency	Low frequency	4	MHz
RF-PHY:P1:2		Middle frequency	4	MHz
RF-PHY:P1:3		High frequency	4	MHz
RF-PHY:P2:1	Value n for Intermodulation test	Low frequency	5	Integer
RF-PHY:P2:2		Middle frequency	5	Integer
RF-PHY:P2:3		High frequency	5	Integer

Inband image frequency is -2 MHz at 1 Mbps and -4 MHz at 2 Mbps for the nRF52 series:

1 Mbps:

2 Mbps:

Hi
I think there is a typo in the table. The Inband image frequency for 1Mbps, middle frequency should be 2438MHz, not 2483MHz (see correction below)

Best regards
