FREQUENCY MEASUREMENTS

Since frequency and time are reciprocals of each other,

when you know one (frequency or time), you can easily

solve for the other (

, then

). Therefore, if you

measure the time period of a recurrent waveform as 0.2

ms, the frequency is 5 MHz (or ).

Note

: Since a DC voltage does not have a frequency,

you cannot make frequency measurements on a DC

voltage.

1. Set the input coupling switch to

GND

2. Connect the

GROUND

(0 volt) wire to the signal

source’s ground or reference level.

3. Rotate the

Zero Level

to vertically center the trace

on the grid overlay.

Note

: If the trace is widened by stray interference,

ground the probe body near the point being mea-

sured. The trace position is the voltage reference

line and all voltage measurements are read in

respect to this line. (Do not adjust the vertical

positioning control after the reference is estab-

lished.)

4. If it was necessary to ground the tip (see Step 3

note), remove the tip from the ground or reference

voltage. This readies the tip so you can use it to

make a measurement.

5. Set the input coupling switch to

6. Click on the vertical cursor icon to

display the vertical cursors. The

Time

box appears below the

grid display.
