SCALE to set the horizontal time base to 50 ms.
7) Rotate HORIZONTAL SCALE to set the horizontal time base to 5 ns.
5. Observe the screen of the oscilloscope. Press CURS  Mode  “Manual” to turn on the manual
cursor function. Measure the offset (ΔT) of the middle point of the signal (namely the crossing
point of the rising edge of the current signal and the trigger level line) relative to the screen
center using manual cursor measurement and record the measurement result.
6. Calculate the time base accuracy, namely the ratio of ΔT to the horizontal position of the
oscilloscope. For example, if the offset measured is 2 ns, the time base accuracy is 2 ns/1 ms =
2 ppm.
7. Calculate the limit of the time base accuracy using the formula “±(4 ppm + 2 ppm/year ×
Number of years that the instrument has been used)”.
