Verify The Test Signal - Agilent Technologies 1670G Series Service Manual

Verify the test signal

Check the clock period. Using the oscilloscope, verify that the master-to-master
1
clock time is 6.666 ns, +0 ps or – 100 ps.
a Enable the pulse generator channel 1, channel 2, and trigger outputs (LED off).
b In the oscilloscope Timebase menu, select Scale: 2.000 ns/div.
c In the oscilloscope Timebase menu, select Position. Using the oscilloscope knob,
position the clock waveform so that a rising edge appears at the left of the display.
d On the oscilloscope, select [Shift] + width: channel 2, then select [Enter] to display the
master-to-master clock time (+ width(2)). If the positive-going pulse width is more
than 6.666 ns, go to step d. If the positive-going pulse width is less than or equal to
6.666 ns but greater than 6.566 ns, go to step 2.
e On the oscilloscope, select [Shift] - width: channel 2, then select [Enter] (- width(2)). If
the negative pulse width is less than or equal to 6.666 ns but greater than 6.566 ns, go
to step 2.
f Decrease the pulse generator Period in 100 ps increments until the oscilloscope +
width (2) or - width (2) read less than or equal to 6.666 ns, but greater than 6.566 ns.
