To Verify Horizontal Delta T Accuracy - Agilent Technologies 6000 Series Service Manual

To verify horizontal delta t accuracy

6000 Series Oscilloscopes Service Guide
The following test is optional because horizontal ∆t accuracy is
a characteristic, not a specification.
This test verifies the horizontal ∆t accuracy. In this test, you
will use the oscilloscope to measure the output of a time mark
generator.
Test limits: ±0.0015% of reading ±0.1% of full scale ±20 ps (same
channel)
Equipment Required to Verify Horizontal ∆t Accuracy
Table 10
Equipment Critical Specifications
Oscilloscope Stability 5 ppm after 1/2 hour
Calibrator
Cable BNC, 3 feet
Ω BNC (f) to BNC (m)
Feedthrough 50
1 Connect the equipment:
a For 300 MHz, 500 MHz, and 1 GHz oscilloscope models,
connect the calibrator output to the oscilloscope channel 1
input.
b For 100 MHz oscilloscopes, use a 50Ω feedthrough
termination to connect the calibrator output to the
oscilloscope channel 1 input.
2 Set up the signal source.
1 Select Marker on the oscilloscope calibrator.
2 Set the calibrator for 100 µs markers (period = 100 µs).
