In RX test mode[ 1 ] RX trigger mode test What signal generator is used? No DIO17 pins on the circuit? When do I need to do this test?
[ 2 ] RX continuous mode test
When do I need to do this test?
I believe that to help you clarify the usage of the tool and the connections you are asking for, could you please help me check this application note?
I found two bug.一。Ch220.127.116.11 of AN12798 requires unmodulate signal, but K32W_Certi_Tools does not have this option.
二。Frequency measurement also requires unmodulated continuous signal to be correct
Could you please check the CW mode? it seems that you are referring to the modulated options.
Please refer to the JN-AN-1242-Customer-Module-Eval-Tool
I have two questions, I will open another topic to ask.
K32W AN12798 bug1
K32W AN12798 bug2
Please check the posts and the internal answers as well.

If PER measurement required, use trigger mode. Else use continuous mode.
Trigger mode needs a trigger signal from the tester. Continuous mode doesn't.
For Rx continuous mode test, the DUT (device-under-test, aka, your design) just keeps receiving all packets, sent from a reference tester. At the end, software counts how many good packets are received (CRC check ok).
If any packet lost in the air, because of the RF interference or other reasons, in the Rx continuous test we will not know. Because we don't know how many packet in total should be received.
So we need the Rx trigger mode test. When the reference tester sends a packet, it also gives a pulse on a wire. This wire would be connected to the Rx side. By counting how many pulses on the wire, the Rx would know how many packet in total. And then it can calculated how many actual packet it received, as well as the PER (packet error rate).
>> What signal generator is used?
Check the RF tester being used. It probably has a trigger signal output, that will connect to your IUT device.
>> No DIO17 pins on the circuit?
I am not sure on this. I suggest you to check the SW implementation of the Certi tool on K32W and QN9090/30
