Im trying to reproduce a wave form acquired with a sensor. I must have very low frequency. I have made a csv files with 1024 datas and with this i cannot have a signal with an initial frequency under 800mHz (at 700mHz and under the output = 0V). With a file with 8192 datas the minimal is 100mHz, under ouput = 0V. With a file 16384 datas minimal is 50mHz.
I have a Picoscope 5443B, PC with windows 7 64bits.
Can you give me a explanation, a soulution?
