Applications
This section describes how to make specific types of measure
ments with your 2225 Oscilloscope. Before performing any pro
cedure, be sure you are familiar with the information contained in
the Operator’s Safety Summary and in Section 1. Preset the instru
ment front-panel controls, using the setup on page 2-5 as a
guideline, and then turn on the power. For maximum measure
ment accuracy, allow a 20-minute warm-up period.
AMPLITUDE MEASUREMENTS
Peak-to-Peak Voltage
This procedure may be used to make peak-to-peak voltage mea
surements, and voltage measurements between any two points
on the waveform.
1. Apply the ac signal to either the CH 1 or the CH 2 input con
nector and set the VERTICAL MODE switch to display the
channel used.
2. Set the appropriate VOLTS/DIV switch to display about 5 divi
sions of the waveform and ensure that the VOLTS/DIV variable
control is in the CAL detent.
3. Adjust the TRIGGER LEVEL control to obtain a stable display.
4. Rotate the SEC/DIV switch to a setting that displays several
cycles of the waveform.
