5000 Series Oscilloscopes Service Guide 33
To verify time scale accuracy
Time Scale Accuracy is a warranted specification for 5000
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.
