Table 4--4 lists the additional characteristics that are designated as checked (
n
)
in the Specifications chapter. These characteristics are indirectly tested by the
performance verification and adjustment software tests named in the table.

1
When the setup and hold time tests are both performed, the setup and hold
window size is indirectly verified.
2
When the setup and hold time tests are both performed, the channel-to-channel
skew is indirectly verified.
3
When all of the tests are performed, including Extended Diagnostics, the
internal sampling period is indirectly verified.
In addition to the basic system setup, you will need some of the equipment
shown in Table 4--1 on page 4--3 to complete the performance verification
procedures.
Each procedure includes a table that calls out the equipment used. Use Table 4--1
for equipment specifications. If you substitute equipment, always choose
instruments that meet or exceed the minimum requirements specified.
