Introduction
The Oscilloscope Calibration Option provides functions that help you maintain your
oscilloscope’s accuracy by verifying the following oscilloscope characteristics:
•
Vertical deflection characteristics are verified by calibrating the voltage gain. The
Volt function lets you compare the voltage gain to the graticule lines on the
oscilloscope.
•
Pulse response is checked using the Edge function, by verifying the accuracy of the
oscilloscope’s measurement of pulse transitions.
•
Frequency response is checked by verifying the bandwidth using the Leveled Sine
Wave function. A leveled sine wave is monitored until the -3 dB point is observed on
the oscilloscope.
•
Horizontal deflection characteristics are verified by calibrating the time base using
the Time Marker function. This calibration procedure is similar to the one for
verifying the vertical deflection characteristics, except that it checks the horizontal
axis.
The menus that implement these functions also include parameters for altering the way
the output signal responds to voltage, frequency, and time settings, giving you control of
the signal during calibration, and providing more methods for observing the signal’s
characteristics.
Oscilloscope Calibration Option Specifications
These specifications apply only to the Oscilloscope Calibration Option. General
specifications that apply to the 5080A Calibrator can be found in Chapter 1 of the
5080A
Operators Manual
. The specifications are valid providing the 5080A is operated under
the conditions specified in Chapter 1 of the
5080A Operators Manual
, and has completed
a warm-up period of at least twice the length of time the calibrator was powered off, up to
a maximum of 30 minutes.
