ps2000_set_sig_gen_built_in not working for micV < 500k

Postby rcox » Wed Apr 09, 2014 11:38 pm

ps2000_set_sig_gen_built_in works fine for values at 500k or above. I'm simply trying to generate a 60 hz sine wave with, in this case, 450,000 peak to peak microvolts.

When hooking another o-scope up to the AWG above that value I get a signal. Below I do not. Is this a known limitation of this call. I am calling it through the Excel macro setup.

Call ps2000_set_sig_gen_built_in(ps2000_handle, 0, 450000, 0, 60, 60, 0, 0, 0, 0)

Thanks for any insights.

You can't set a value between -250mV and +250mV, this is a hardware limit and applies for Picoscope6 as well as software written to use the dll.
