Normal Sweep Display - Tektronix 2212 User Manual

Non-Store Displays
Normal Sweep Display
2- 6
With the 2212 in the normal (continuous) mode, you can use the
following procedure to display the sweep:
Step
1.
Switch the 2212 on and obtain a baseline display in
Non-Store mode.
Step 2. Using a lOX probe or a properly terminated coaxial ca-
ble, apply a signal to the CHl OR X input connector.
The signal source output impedance determines the
termination impedance required when using a coaxial
cable to interconnect test equipment.
NOTE
Instrument warm-up time required to meet all specification
accuracies is
20
minutes.
Step 3. If the display is not visible with the INTENSITY control
at midrange, you can :
- Press the BEAMFIND button and hold it in while
adjusting the CH 1 VOL TS/DIV switch to reduce the
vertical display size. Center the compressed display
using the Vertical and Horizontal POSITION
controls. Release the BEAM FIND button.
- Press the AUTO SETUP button, which automatically
sets the vertical, horizontal, triggering and display to
produce a usable, stable, triggered display.
Step
4.
Set the CHl VOL TS/DIV switch and adjust the Vertical
and Horizontal POSITION controls to locate the display
in the graticule area.
Step 5. Adjust the Trigger LEVEL control for a stable, triggered
display.
Step 6. Set the SEC/DIV switch for the desired number of cycles
of displayed signal. Then adjust the FOCUS control for
the best defined display.
NOTE
Amplitude measurements are usually made with many
complete cycles displayed. Period time, rise time and
fall time measurements are made at the fastest sweep
speed that allows only the area of measurement to be
seen on screen.
