Figure 3-35: Period Measurement
Measuring Frequency
Frequency is measured by calculating the inverse of a period measurement
(1/AT). With a graticule measurement you would have to calculate this
yourself. Using the Display menu, however, you can set the STORE mode
cursors to display the frequency:
n Step 1: Press the Setup DISPLAY button on the front-panel.
□ Step 2: Push the left bezel button to place the selection box around
“1/AT." Push the DISPLAY button again to return to the storage acquisi
tion display.
F I Step 3: Position a cursor on the rising edge of the waveform where it
crosses a graticule line.
F I Step 4: Push the CURSORS knob in to select the other cursor and
position it at the same transition point on the next cycle of the signal
(Figure 3-36).
□ Steps : Note the 1 /AT (frequency) readout in the upper right corner of
the display.
