1. Pressing the Unit option button selects between V (Volts) and A
(Amperes) values.
2. Pressing the Skew option button enables the Adjust front panel knob to
set your desired value.
Acquisition Types
When you acquire a signal, the oscilloscope converts it into a digital form and
displays a waveform. The acquisition sampling mode defines how the signal is
digitized and the timebase setting affects the time span and level of detail in
the acquisition. You can change the Sampling modes by pressing the ACQUIRE
front panel button.
There are three basic acquisition types:

Error! Bookmark not defined.Sampling- samples the signal in evenly-
spaced intervals to construct the waveform. You can use this type to
reduce random noise. This type does not acquire rapid variation in the
signal that may occur between samples. This can result in narrow pulses
being missed. In this case, use Peak Detect to acquire data.

Error! Bookmark not defined.Peak Detect - captures the maximum and
minimum values that occur in a signal. It finds the highest and lowest
record points over many acquisitions. The oscilloscope can acquire and
display narrow pulses, which may otherwise have been missed in
Sampling mode. Noise appears higher in this mode.

Average - acquires up to 256 waveforms, averages them, and displays
the resulting waveform. This type can be used to reduce random noise.
