Technical Information
For all the time scales, the Peak Detect resolution remains fast enough to catch
transient events – even if the time scale is set much slower. This is possible
because max and min voltage values are stored for each sample period.
When the saved wave is reviewed, the max / min voltages appears as a vertical
line. You will not be able to zoom in on any details at a slow time scale but you
will see the transient event.
Example of 5 uS transients using a slow
sample rate (1 Sec/Div). In this case
one pixel represents 50mS. but the 5uS
transient still shows the voltage change.
Voltage Scales
During Live wave viewing there are eight
Auto Wave II amplifier gain settings. The
voltage scale setting at the time a wave
is captured determines the resolution of
the digitized wave. Below is a chart that
shows the scales and the resolution.

Auto Wave II Voltage Scales are compressed 4X for live viewing. The captured
wave can be expanded to show more voltage detail than could be seen during
the live viewing.
A main menu Voltage Range selsection sets the dynamic range for both channels.
The D/-100V is used for dual polarity (plus and minus) signal viewing. This
setting will display the five voltage divisions in either direction (see chart above).
Exceeding five divisions will cause the wave to be clipped. The single polarity
settings Po200V and Negative -200V will display ten voltage divisions in
single polarity.
