Time Base Accuracy Test
Specification:
Time Base Accuracy
≤ ±
50 ppm
Test Devices: Fluke 9500B or signal generator and BNC (m)-BNC (m) cable.
Test procedures:
1) Connect the active head of Fluke 9500B to CH1 of the oscilloscope.
2) Output a sine waveform with 10 MHz frequency and 1 Vpp amplitude from
Fluke 9500B.
3) Configure the oscilloscope:
a) Press CH1 in the vertical control area (VERTICAL) at the front panel to
enable CH1.
b) Rotate VERTICAL SCALE to set the vertical scale to 200 mV/div.
c) Rotate VERTICAL POSITION to set the vertical position to 0.
d) Rotate HORIZONTAL SCALE to set the horizontal time base to 20
ns.
e) Rotate HORIZONTAL POSITION to set the horizontal position to
1 ms.
4) Observe the display of the oscilloscope and measure the offset (ΔT) of the
midpoint of the signal relative to the center of the screen.
5) Calculate the time base accuracy, namely the ratio of ΔT to the horizontal
position of the oscilloscope. For example, if the offset of this test is 8 ns, the
time base accuracy is 10 ns/1 ms=10 ppm.
