11. Adjust the oscilloscope vertical position control if necessary to
center the resulting waveform. Store and then recall the
waveform.
12. Use the cursor measurement capability of the oscilloscope to
display the
D
voltage of the recalled waveform. Measure the
low-frequency portion of the waveform near the back corner.
Record the
D
voltage as V

Rise Time Check
Use the following procedure to confirm that the P6205 probe
performs within its Rise Time specification limits.
NOTE
. If you do not have access to an 11800 Series oscilloscope, a
method for approximating probe rise time using a pulse generator
and a TDS 500 or 11000 Series oscilloscope follows this procedure.
