Chapter 1 Overview
Test Preparations
The following preparations should be done before the test:
1. Self-test
2. Warm-up (make sure that the instrument has been running for at least 30 minutes)
3. Self-calibration
Self-test
When the oscilloscope is in power-on state, press the power key at the lower left corner of the
front panel to start the oscilloscope. During the start-up, the instrument performs a series of self-test
items and you can hear the sound of relay switching. The welcome screen is displayed after the
self-test is finished. You can view the self-test results by pressing Utility System
SelfTestInfo.
If the self-test fails, make sure that the problems are found and resolved and do not perform
self-calibration and performance tests until the instrument passes the self-test.
Self-calibration
Make sure that the oscilloscope has been warmed up or running for more than 30 minutes before
performing self-calibration.
1. Connect the analog input channels and the external trigger input channel of the oscilloscope to the
[Trig Out/Calibration] connector at the rear panel respectively using a one-to-five BNC (M)
cable.
2. Press Utility Self-Cal at the front panel and press Start to execute self-calibration.
3. The self-calibration lasts for about 30 minutes (20 minutes for dual-channel models). After the
self-calibration is finished, the corresponding prompt message is displayed. At this point, please
restart the instrument.
4. Press Acquire; press Acquisition to select “Average” and press Averages to set it to 16.
5. Disconnect the input signals of all the channels. Set the vertical scale of each channel to 2 mV/div
and view the offset of the waveform of each channel. If the offset is greater than 0.5div, you
should perform self-calibration again.
Test Result Record
Record and keep the test result of each test. In the Appendix of this manual, a test result record form
which lists all the test items and their corresponding performance limits as well as spaces for users to
record the test results, is provided.
Tip:
It is recommended that users photocopy the test record form before each test and record the test
results in the copy so that the form can be used repeatedly.
