I'm working on a BLOCK mode example and I've got it reading DC fine. The user is prompted for Channel, Range, AC/DC and number of samples. Works fine and I'm playing around with the overFlow flags.
Now I would like to measure AC signals, however if I simply change from DC to AC in channel setup, I get nothing back.
Are there additional settings needed to read AC signals?
my basic events are:
prompt user for chan, range, #samples, AC or DC
ps2000_set_channel (with this info)
ps2000_run_block to collectdata
wait for ready
ps2000_get_values to pull it from the array
display the information
If it is DC I get back the ~1.6V I'm applying, but if I select AC what I see looks like there is nothing connected to the input.
Thanks for any help.
