Chapter 3: Testing Performance

To Test the Multi-Card Module

Verify the test signal

1 Check the clock period. Using the oscilloscope, verify that the master-to-

master clock time is 5.000 ns, +0 ps or -100 ps.

a Turn on the pulse generator channel 1, channel 2, and trigger outputs.

b 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.

c On the oscilloscope, select [Shift] Period: channel 2, then select [Enter]

to display the clock period (Period(2)). If the period is more than 5.000

ns, go to step d. If the period is less than or equal to 5.000 ns but

greater than 4.900 ns, go to step 2.

d In the oscilloscope Timebase menu, increase Position 5.000 ns. If the

period is more than 5.000 ns, decrease the pulse generator Period in 10

ps increments until one of the two periods measured is less than or

equal to 5.000 ns but greater than 4.900 ns.
