H Set horizontal scale to control the size of the horizontal acquisition window
to capture as much as you want of the input signal(s). Set the horizontal
position to delay the window relative to a trigger and to control where in the
input signal (data stream) that the horizontal acquisition window acquires.
For more background on acquisition window concepts, see Input Conditioning
Background on page 3--19.
The instrument can automatically obtain and display a stable waveform of usable
size. Pushing the Autoset button automatically sets up the instrument controls
based on the characteristics of the input signal. Autoset is much faster and easier
than a manual control-by-control setup.
The instrument can also be reset to its factory default settings.
Usage of some input conditioning controls or features may be limited when other
control settings are in effect. Voltage offset is incompatible with reference
waveforms because offset is an acquisition control.
Read the following topics related to waveform acquisition; they provide details
that can make it easier to set up and acquire your waveforms.
Probes and Signal Connection. Select the probe or cable that brings the signal into
the instrument. Choose the probe or cable that best fits your acquisition task,
whether it is connecting an active probe to test a digital circuit, or connecting to
a test fixture through SMA cables to characterize a device. The connection to the
instrument depends on your application.
Tektronix provides a variety of probes and cables for this product. For a list of
probes available for use, see Accessories and Options on page 1--37. You can
also check your Tektronix catalog for connection accessories that may support
your application. More information about your probes can be found in the user
manual for your probes.
Four acquisition channels are available. Each channel can be displayed as a
waveform or can contribute waveform data to other waveforms (math and
reference waveforms for example).
