Hello,
I am wondering if my device does not work or if I am doing something wrong:
I measure e.g. a capacitor charge/discharge.
I set the DSO203 to single sync mode, sampling time 100ms, channel A only.
I set the trigger point T0 to the left of the display. The memory depth is 4K.
After pressing the run button and running a charge/discharge cycle, I can see the voltage measured over the capacity (both charge and discharge) nicely.
I then set the sampling time to 10ms. All other parameters stay the same.
I can see the initial part of the curve (initial charge). I assume the remaining is in the non visible part of the memory buffer.
However, I thought I would use the "X" control to scroll through the memory buffer. In fact doing so, I see the tiny rectangle scroll to the right on the top right of the display. However, the main display does not update at all and stays the same all time.
What is going wrong?
HW 2.70
SYS Ver 1.52
APP (PLUS A1) V1.07
and one more question: I can set the trigger point on the time axis only to 2 points, about 25% from left and about 75% from left, but not to the center of the display. Is that correct?
Tank you for any help! |
