DIAGnostic
•
The <offset> parameter specifies the conversion offset at zero input volts. This
parameter is also commonly known as the "Y-intercept."
•
<ch_list> specifies which channels may use this custom linear function.

Send with VXIplug&play Function: hpe1422_cmd(...)
Usage DIAG:CUST:MXB 2.1,.19,(@10000:10131)
create table for chs 0000-0131
SENS:FUNC:CUST 1,1,(@10000:10131)
link custom EU with chs 0000-0131
DIAGnostic:CUSTom:PIECewise
DIAGnostic:CUSTom:PIECewise <table_range>,<table_block>, (@<ch_list>)
downloads a custom piece wise Engineering Unit Conversion table (in <table_block>)
to the VT1422A. Contact a VXI Technology System Engineer for more information
on Custom Engineering Unit Conversion for specific applications.
Parameters
Comments •
The <table_block> parameter is a block of 1,024 bytes that define 512 16-bit
values. SCPI requires that <table_block> include the definite length block data
header. The VXIplug&play function hpe1415_sendBlockUInt16(ViSession vi,
ViString cmd_str, ViInt32 table[ ], ViInt32 size) adds the header automatically.
•
The <table_range> parameter specifies the range of voltage that the table covers
(from -<table_range> to +<table_range>).
•
The <ch_list> parameter specifies which channels may use this custom EU table.
