The Agilent E5022/E5023 can delay the write timing of the write operation when
writing the data pattern. This timing delay is defined as three bits off the target bit
(prebit or postbit). Three timing delays can be added to the time position of the write
data bits. And three data patterns can be selected to precompensate the data, namely;
'PRBS' (pseudo random bit sequence), 'NLTS 5th' and 'User Defined Pattern'.

NOTE
Although, the DLL function of Agilent E5022/E5023 supports both the prebit and postbit,
the VEE measurement program supports only the prebit. See the
"hpe5022_precompPattern" function in the programming manual for details.

Three types of data pattern can be selected for precompensation delay from the
'Precomp Status' frame.
Click on [Delay1], [Delay2] and/or [Delay3] to set the delay time. Each
corresponding [Add Pattern] is used to select the type of precompensation pattern
as shown in Figure 4-3.
When you click on [Add Pattern] a dialog box 'Precomp Pattern Select' will
pop-up. Select the type of precompensation pattern for the specified data pattern of
'Precomp Status' frame as shown in Figure 4-3.
To delete any precompensation pattern previously selected, click on [Delete
Pattern] and select the precompensation pattern to be deleted as shown in Figure
