BASIC APPLICATIONS
INTRODUC'TION VOLTAGE MEASUREMENTS
The information in this part is designed to enhance
operator understanding and to assist in developing
Peak-to-Peak Voltage
efficient techniques for making specific measurements.
Recommended methods for making basic measure-
ments with your instrument are described in the To make a peak-to-peak voltage measurement, use the
procedures contained in this section.
following procedure:
When a procedure first calls for presetting instrument
controls and obtaining a baseline trace, refer to the
Operator's Checks and Adjustments part in this section
NOTE
and perform steps 1 through 4 under Baseline Trace.
This procedure may also be used to make
voltage measurements between any two points
on the waveform.
