Horizontal Dt And 1/Dt Accuracy Verification Test - Agilent Technologies U1602B User's And Service Manual

Horizontal
This test verifies the horizontal Δt and 1/ Δt accuracy. In this test, you
will use the oscilloscope to measure the output of a time mark generator.
Test limits: ±3% reading ±0.4% screen
Refer to Table 7- 1 for the equipment required for this horizontal Δt and
1/ Δt accuracy verification test.
