Program the Table
If a table does not exist, you must program a new table. Programming a
table consists of entering voltage data and current data to create the
desired number of I-V coordinate-pairs. The number of voltage values
must match the number of current values.

To create a new a table for output 1:
MEM:TABL:SEL name,(@1)
To enter voltage data for the table:
MEM:TABL:VOLT 0,5,10,50,55,(@1)
To enter current data for the table:
MEM:TABL:CURR 4,4,3.5,3,2.5,(@1)
Table Restrictions
A table must have a minimum of three I-V points and can have up to
4000 I-V points, but an equal number of voltage and current values must
be sent. Otherwise an error will occur when the table is selected with
CURR:TABL:NAME. Use MEM:TABL:CURR:POIN? and
MEM:TABL:VOLT:POIN? to find the length of an existing table.
Points must be above dashed line shown in the previous figure. There is
no restriction on the spacing or gap between the voltage or current
values, but the values must be monotonic. Voltage values must be sent
in increasing order of magnitude; current values must be sent in equal or
decreasing order of magnitude. For a Keysight E4361A for example: (1,8)
(50,7.8) (55,7.5) (56,7) (57,6) (58,4) (59,1).
Each I-V point, when combined with the table offset, cannot exceed the
unit's maximum voltage, current, or power.
A table cannot be deleted or redefined while it is selected.
The following table lists the maximum parameter restrictions by output
module.
