Other commands used to set up strain measurements are:
[SENSe:]STRain:POISson
[SENSe:]STRain:EXCitation
[SENSe:]STRain:GFACtor
[SENSe:]STRain:UNSTrained
See the Chapter 5 and the HP E1506/E1507 User’s Manual for more
information on strain measurements.
Linking Custom
EU Conversions
There are two major steps to link channels to custom EU conversions:
1. Load the custom EU conversion table values into the HP E1413.
These values will be in the form of a numeric array. (Contact your
HP Field Engineer for assistance in generating the EU conversion
table values.)
2. Link channels to the custom EU conversion table.
Loading Custom
EU Tables
There is a specific location in the HP E1413’s memory for each channel’s
EU conversion table. When standard EU conversions are specified, the
HP E1413 loads these locations with EU conversion tables copied from its
non-volatile FLASH Memory. For custom EU conversions you must load
these table values using either of two SCPI commands.
Loading Tables for
Linear Conversions
The
DIAGnostic:CUSTom:LINear <
table_range
>,<
table_block
>,(@<
ch_list
>)
command downloads a custom linear Engineering Unit (EU) conversion
table to the HP E1413 for each channel specified.
•
<
table_block
>
is a block of 8 bytes that define 4, 16-bit values. SCPI
requires that
<
table_block
>
include the definite length block data
header. C-SCPI adds the header for you.
•
<
table_range
>
specifies the range of input voltage that the table
covers (from –
<
table_range
>
to +
<
table_range
>
). The value you
specify must be within 5% of:
.015625 | .03125 | .0625 | .125 | .25 | .5 | 1 | 2 | 4 | 8 | 16 | 32 | 64.
•
<
ch_list
>
specifies which channels will have this custom EU table loaded.
Usage Example
Your program puts table constants into array table_block.
DIAG:CUST:PIEC
table_block
,1,(@132:163)
Send table for channels 32-63 to
HP E1413.
SENS:FUNC:CUST 1,1,(@132:163)
Link custom EU with channels
32-63 and set the 1V A/D range.
