2-3. MEASUREMENT APPLICATIONS

This section contains instructions for using your OS-5060A for specific measure-

ment procedures. However, this is but a small sampling of the many applications

possible for this oscilloscope. These partcular applications were selected to demonstrate

certain controls and features not fully covered in BASIC OPERATING PROCEDURES,

to clarify certain operations by example, or for their importance and universality.

2-3-1. Amplitude Measurements

The modern triggered sweep oscilloscope has two major measurement functions.

The first of these is amplitude. The oscilloscope has an advantage over most other forms

of amplitude measurement in that complex as well as simply waveforms can be totally

characterized (i.e., complete voltage information is available).

Oscilloscope voltage measurement generally fall into one of two types : peak-to-

Peak or instantaneous peak-to-peak (p-p) measurement simply notes the total amplitude

Between extremes without regard to polarity reference. Instantaneous voltage measure-

ment indicates the exact voltage from each every point on the waveform to a ground

reference. When making either type of measurement, make sure that the VARIABLE

controls are click-stopped fully clockwise.

Peak-to-Peak Voltage. To measure peak-to-peak voltage, proceed as follows.

1. Set up the scope for the vertical mode desired per the instructions in 2-3 BASIC

OPERATING PROCEDURES.

2. Adjust the TIME/DIV switch (22) or (23) for two or three cycles of waveform, and

set the VOLTS/DIV switch for the largest-possible totally-on-screen display.

3. Use the appropriate Vertical POSITION control (17) or (18) to position the negative

signal peaks on the nearest horizontal graticule line below the signal peaks, per

Figure 2-6.
