To obtain different kinds of characteristics of some sensors and other electronic devices I normally use DSO and proceed as follows: 1) The DSO is set in both XY plot mode (Ch1 data is displayed on Y axis and Ch2 data is displayed on X axis) and Persistence mode (the scope captures many acquisitions of a signal to the screen and record points accumulate); 2) The voltage proportional to the input sensor signal is connected to Ch2 input and the voltage proportional to the output sensor signal is connected to Ch1 input; 3) The operator manually, using a benchmark, increases (decreases) input sensor signal, and the voltage proportional to the output sensor signal increases (decreases) respectively. The obtained characteristic is depicted on the screen.
For such purposes I used DSO GwINSTEK GDS-2104 and Velleman PCSU 1000. One example of the obtained by described above way characteristics is shown in the enclosed picture “PCSU1000_XY_Plot&Persist.jpg”. (This particular characteristic is linear.) Note that both of the buttons “Persist” and “XY plot” are switched on.
Recently I bought a DSO PicoScope 3224. I try to use it in conjunction with the software PicoScope 6 installed on PC for described above purposes. Unfortunately, I could not manage to set the DSO in both XY plot mode and Persistence mode simultaneously using the PicoScope 6 software: if the scope is in Persistence mode, it is impossible to switch XY plot mode additionally; if the scope is in XY plot mode and switch Persistence mode, the XY plot mode “disappear”.
Please give me advice how to resolve the described above problem – is it possible to switch PicoScope 3224 in both XY plot mode and Persistence mode simultaneously in order to obtain XY plot of different device characteristics (like as DSO GwINSTEK GDS-2104 and Velleman PCSU 1000)?
