6000L Series Oscilloscopes Service Guide 37
To verify time scale accuracy
Time Scale Accuracy is a warranted specification for 6000L Series oscilloscopes
manufactured after January 1, 2008.
If your oscilloscope’s serial tag has old-style (linear) barcodes instead of the 3-D
barcodes shown above, or if the date indicated on the serial tag is older than
January 1, 2008, then disregard this test.
This test verifies the accuracy of the time scale. In this test you will measure the
absolute error of the timebase oscillator and compare the results to the
specification.
1 Set up the signal generator.
a Set the output to 10 MHz, approximately 1 V
pp
sine wave.
2 Connect the output of the signal generator to oscilloscope channel 1 using the
BNC cable.
