HOW TO USE THE INSTRUMENT 4 - 71
4.16 AUTOSET AND SETUP UTILITIES
This oscilloscope has a number of utilities that assist you to quickly get to the
setup you need.
One utility is the SET STANDARD utility to set the oscilloscope to a factory-
defined, known state.
The most frequently used utility will be AUTOSET. AUTOSET is user
programmable as outlined below.
SET STANDARD
- Simultaneously press the STATUS and TEXT OFF keys.
The standard setting feature resets all functions to a predefined state. At this time it
must be used to ensure that the standard setup condition applies before proceeding.
SET STANDARD also resets the autoset function to the standard autoset condition.
AUTOSET STANDARD
The AUTOSET function automatically sets all relevant functions of the
oscilloscope as they apply to the input signal. This includes the
selection of channels, input sensitivity, timebase setting, trigger
source, trigger slope, and trigger level for an optimum trace.
- Connect the Probe Adjust output to channel 1.
- Press the AUTOSET key.
The result is a stable display with a number of signal periods. The amplitude is
well within the display range. In this example the Probe Adjust signal is displayed
with four periods/cycles on the screen and an amplitude of three divisions. This
operating mode is referred to as AUTOSET after the SET STANDARD.
