BASIC OSCILLOSCOPE APPLICATIONS
The 5441 and its associated plug-in units provide a very
flexible measurement system. The capabilities of the overall
system depend mainly upon the plug-ins that are chosen.
The following information describes the techniques for mak-
ing basic measurements. These applications are not de-
scribed in detail, since each application must be adapted to
the requirements of the individual measurement. Specific
applications for the individual plug-in units are described in
the manuals for these units. Contact your local Tektronix
Field Office or representative for additional assistance.
The following books describe oscilloscope measurement
techniques which can be adapted for use with this
instrument.
form. Check that the variable VoltsIDiv control (red knob) is
in the Cal position.
3. Adjust the time-base triggering controls for a stable
display and set the SecIDiv switch to display several cycles
of the waveform.
4. Turn the vertical Position control so that the lower
portion of the waveform coincides with one of the graticule
lines below the center horizontal line, and the top of the
waveform is in the viewing area. Move the display with the
horizontal Position control so that one of the upper peaks is
aligned with the center vertical reference line (see Fig. 2-6).

Peak-to-peak Voltage Measurements-AC
To make peak-to-peak voltage measurements, use the
following procedure.
1. Set the input coupling on the vertical plug-in unit to
Gnd and connect the signal to the input connector.
