Rise-Time M easurements
Making rise-time or fail-time measurements requires some additional signal

90, and 100 are etched near the left vertical graticule line. These numbers
provide convenient reference points for making rise- and fall-time measure
ments when the signal to be measured is properly set up. Use the following
