Cycle time for the measurement acquisition ³ 250 µs.
Various value are graphically displayed in a diagram. You can display up to three variables simultaneously, as a
function of time.
Start
Start recording the data.
Stops recording the data
Cancel
Saves the recorded measurements to a data medium in CSV format (to be evaluated with MS-Excel).
Save
Loads a CSV data file and displays the curves on the oscilloscope diagram.
Load
Assignment of the displayed variables to the channels. At present, the following variables can be selected:
Channel
I_act
v_act
VBUS
Off
For each channel: the range of measurement can be selected automatically (Auto checkbox is active) or
manually (Auto checkbox is inactive, and min./max. values have been entered).
Mem
If this is active when a new curve is recorded, the previous measurement is saved, so that a comparison can be
made between two measurements. The previous measurement curve is displayed in a darker color than the
latest curve. The measurement range settings must be identical for both measurements. If this is not so, the
"Mem" checkbox will be de-activated and locked.
Auto/Min-Max
Change-over of the scaling of the coordinate system from automatic to minimum/maximum
Update
Loads and displays the latest set of data that was recorded, provided that this set has not been erased or
overwritten.
Trigger level
Y-value for triggering.
Trigger position
X-value for triggering (time axis)
Triggering on the rising or falling edge.
