I used it to activate all options on my SMIQ03B, I was just wondering how to use the 802.11a and 802.11b functionalities, they are listed as activated on the device but I can't find the corresponding menu nor any explanation in the user manual
I think you are talking here about option SMIQK19. Any SMIQ options with the letter "K" in them (SMIQK11 through SMIQK20) refer to waveform playback in combination with the WinIQSIM software (the original one, WinIQSIM2 will not do...)
you need SMIQ-B60 Arbitrary Waveform Generator,then MENU → DIGITAL MOD → ARB → WinIQSIM
True... SMIQ-B60 itself is also a software-activated option.
But you will also need some hardware. More specifically, you will need the SMNIQ B11 ("Data Generator") card installed. It comes with a modest 16Mbit (2MB) amount of memory for waveform playback, and you can add option B12 to add 32Mbit additional memory, or twice B12 to add 64Mbit additional memory.
If you have B60, then the good news is that it is actually quite possible to get it working! I show that in the below video. Also, the modest memory in the SMIQ allows you to play back much 'larger' wave files than you might expect, due to some clever design. Also talk about that in the video.
Good luck!
