Hey,
I recently bought couple of 2.4GHz high speed low cost transceivers. I was wondering if, instead of a PIC, i could send data using a function generator. the function generator im using is Agilent 33120A with a max. frequency of 15MHz.
also in the LAIPAC TECH sheet, i see antenna section. im guessing i dont have anything to take care of here since it already connected to the transceiver…rite?!?
You don’t have to worry about anything other than clocking in the data for that module. Well, a power supply would help, I 'spose.
Do it with a function generator? I seriously doubt it. I mean, it’ll take a clock signal and a seriously arbitrary waveform on the data line. Dont’ get me wrong, you’ll have my greatest respect if you manage to do it that way. But I’ve got a fair amount of experience with that function generator, and I just thing it’ll take you a lot more time to do it that way than to do it with a PIC.
Good luck, man. I’m rooting for you.

haha,
thanks man.
i got it to work using a function generator, but as you mentioned it took me some time.
the output i got had very low output voltage at abt 100mV Vpp even though the input had Vpp 3V. when i tried putting the data output into an a 741 opamp and seeing the output, but the output data gets very much distorted. the data without the opamp had quite a lot of noise.
any suggestions?!?
You got it to work??? Way to go! You must know that generator better than I do (or care to, for that matter).
Low output, eh? What’s your output power set to? If it’s -20dBm, you’ll probably see around 126mV with an open load (I calculate 63mV into 400 ohms). If it’s set to 0dBm, you’ll probably see something over a volt.
I haven’t looked at a 741 data sheet in about 10 years. I don’t remember what it’s slew rate is, but I’m betting it aint good. As for regular old noise, decouple the bejeezus out of it, run it with a battery, and keep your input nodes small and as short as possible.
