O
SCILLOSCOPE
The oscilloscope works like a real 3-channel-oscilloscope. Content, scaling type and offset of the
three channels is selectable.
Channel selection:
is done from a drop down list, which shows only the available channels.
The two
numbers
above the drop down list for channel selection display the “scaling factor per
vertical division” (= left number, hint: “y-scale in /div”, example: 12.90 nV/div) and the mean
value. Both are calculated from all data acquired from the left oscilloscope edge till the current
oscilloscope time. Therefore, these numbers are subsequently re-calculated.
Vertical scaling types:
•
0..max
the scaling is set to maximum value of the channel
•
0..fixed
the maximum value can be changed by a slider appearing on the right
sight of the scaling type selection
•
0..auto
the program calculates the optimum, but takes always “0” as minimum
•
auto..auto
automatically scaled
Time scaling
is done with the edit window (right sight) in seconds.
“Save Pic”
saves the oscilloscope screen in a bitmap file.
“Draw mode”
selects whether the data are drawn as dots or lines.

CONSTANT
This option selects the used time constant for the low-pass filter. The internal LockIn functions give
the lower limit of 0.2 ms (5 kHz). The possible time constants range in a logarithmic scale between
0.2 ms and 1 s.
