Rise Time Measurement
in Store Mode
3- 30
To measure the rise time of a waveform in Store mode, you can
use the following procedure:
Step 1. Switch the 2212 on and obtain a baseline display in
Non-Store mode.
Step 2. Apply the signal to the CHl OR X or CH2 OR Y input
connector and toggle the Vertical MODE switch to
display the channel used.
Step 3. Adjust the Trigger LEVEL control to obtain a stable
display.
Step 4. Set the SEC/DIV switch and alter the Vertical POSITION
control so that the zero reference of the waveform
touches the 0% graticule line and the top of the wave-
form the 100% graticule line.
NOTE
Make sure that the VOLTS/DIV switch is in the calibrated
position with risetimes faster than 0.5 µs.
Step 5. Set Cursors ON/Off switch to ON.
Step 6. Toggle the 1Wl/,::W2/~T/1/,H switch to the ~T position.
Observe that two vertical cursors appear on the crt.
Step 7. Press STORAGE ON/Off switch to Store ON. This will
result in the cursors becoming "attached" to the wave-
form. Notice a highlighted dot at the crossings of the
cursors and the waveform.
Step 8. Position the cursors to the 10% and 90% points of the
waveform, using the Cursor POSITION and TOGGLE
CURSOR controls and read the time difference between
the two cursors from the crt readout.
