Agilent Technologies 1690, 1680 manual Check the setup/hold combination

Chapter 3: Testing Performance

To test the single-clock, single-edge, state acquisition

cIf the pulse width is outside the limits, adjust the pulse generator channel 2 width until the pulse width is within limits.

Check the setup/hold combination

The following setup/hold combinations will be tested:

Setup/Hold Combinations

Test	Setup/Hold	Setup/Hold	Sample Position
Combination	Times	Window	(in middle of Window)
1	4.50/-2.0 ns	2.5 ns	-3.25 ns
2	-2.0/4.50 ns	2.5 ns	+3.25 ns

1Disable the pulse generator channel 1 COMP (with the LED off).

2Using the Delay mode of the pulse generator channel 1, position the pulses

according to the setup time of the setup/hold combination selected,

+0.0 ps or −100 ps as measured on the oscilloscope:

a On the Oscilloscope, select [Define meas] Define ∆ Time - Stop edge: rising, Edge number 2.

b In the oscilloscope timebase menu, select Position. Using the oscilloscope knob, position the data waveform so the falling edge is near the center of the display.
