How to capture channel 2 's frames when wireless interface was set to channel 1

Hi ALL:

How to capture channel 2 's frames when wireless interface was set to channel 1.
Wireless card is in mode 11g.
Bandwidth is 20MHz, between channel 1 and 2 is 5MHz, 20MHz include channel 2.
So it's can capture channel 2's frames when wireless card is set in channel 1.
Is that right?
Thank you.
