Hello, I'm trying to use the AD2 pattern generator to create a (digital) sine wave using a value table table. I connected the external trigger to a clock of 10MHz, to create a sine with the frequency of 10/1024 MHz (with 1024 being the size of the table). When I compare the resulting sine wave to a sine wave generated by an FPGA, using a look-up table with the same size and clock, I see that both signals drift apart from each other, even though both of them seem to have the same period. Am I using this tool the wrong way? Is my setting for a trigger wrong somehow?
Hi all, I struggled for a while with unexpected DC outcomes from the datalogger. After research I found a DC temperatuur drift error. I think this affects the oscilloscope and voltmeter tool as well. If you watch the attached picture you see a 2 hour record of a 3,3V DC channel (1) and a zero volt (shorted) channel (2). You see a temperature / voltage drift in the range from -38,75 mV by 22 °C to + 2,4 mV by 43,75 °C. The only point where this drift is zero is after 1 hour. For me this DC drift makes the mV range useless and even in the Volt range i have to wait an hour before i have more
