12. Divide the displacement between the vertical cur-

sors (the value shown in the box) by the

value in the timebase (time-per-division), then

multiply the result by the number of degrees per

division calculated in Step 11.

Note: The relative amplitude of the measured sig-

nals does not affect the phase measurement if the

signals are centered around the grid’s center hori-

zontal line.

Single Sweep Waveform Measurements

You can measure a waveform that occurs only once

without repeating, such as a noise spike that occurs

when you turn on an electronic device.

Follow these steps to measure a single sweep wave-

form.

1. Continuously press the Menu button until the trig-

ger

mode appears on the display.

2. Set the input coupling switch to

GND

3. Connect the

GROUND

(0 volt) wire to the signal

source’s ground or reference level.

4. Rotate

Zero Level

to vertically position the trace to

a convenient line on the grid overlay.
