5.15 NUMeric Group

The command in this group deal with numeric data output.
There are no front panel keys that correspond to the commands in this group.
:NUMeric?
Function Queries all numeric data output settings.
:NUMeric?
Syntax
:NUMeric:BYTeorder
Function Sets or queries the output byte order of the
numeric data (FLOAT format).
:NUMeric:BYTeorder {LSBFirst|
Syntax
MSBFirst}
:NUMeric:BYTeorder?
Example :NUMERIC:BYTEORDER LSBFIRST
:NUMERIC:BYTEORDER?
-> :NUMERIC:BYTEORDER LSBFIRST
Description • This command is valid when :NUMeric:FORMat
is set to FLOat.
• The default setting on the WT5000 is LSBFirst.
If you specified a command type that is
compatible with legacy models (see chapter 7),
the default setting is MSBFirst.
:NUMeric:FORMat
Function Sets or queries the numeric data format.
:NUMeric:FORMat {ASCii|FLOat}
Syntax
:NUMeric:FORMat?
:NUMERIC:FORMAT ASCII
Example
:NUMERIC:FORMAT?
-> :NUMERIC:FORMAT ASCII
Description • The format of the numeric data that is output
varies depending on how this command is set.
The different formats are explained below.
- When the format is set to ASCii:
Physical values are output in <NR3> format.
(Only the elapsed integration time—ITIMe—
is output in <NR1> format.)
The data items are separated by commas.
- When the format is set to FLOat:
A header (for example, "#6000060") is added
in front of each numeric data block.
A physical value in IEEE single-precision
floating point (4-byte) format follows the
header.
The byte order of the data of each item is
MSB First.
• For the formats of each individual numeric data
item, see "Numeric Data Formats" at the end of
this group on page 5-81.

:NUMeric:HOLD
Function Sets or queries the on/off (hold/release) status of
the numeric data hold feature.
:NUMeric:HOLD {<Boolean>}
Syntax
:NUMeric:HOLD?
Example :NUMERIC:HOLD ON
:NUMERIC:HOLD?
-> :NUMERIC:HOLD 1
Description • If :NUMeric:HOLD is set to ON before
:NUMeric[:NORMal]:VALue? or :NUMeric:LIST:
VALue? is executed, all the numeric data at
that point in time can be held internally.
• As long as :NUMeric:HOLD is set to ON,
numeric data is held even when the numeric
data on the screen is updated.
• For example, if you wish to retrieve various
types of numeric data from each element
at the same point in time, use the following
commands:
:NUMeric:HOLD ON
:NUMeric[:NORMal]:ITEM1 URMS,1;
ITEM2 IRMS,1;...
(Set the numeric data items of element 1.)
:NUMeric[:NORMal]:VALue?
(Receive the numeric data of element 1.)
:NUMeric[:NORMal]:ITEM1 URMS,2;
ITEM2 IRMS,2;...
(Set the numeric data items of element 2.)
:NUMeric[:NORMal]:VALue?
(Receive the numeric data of element 2.)
:NUMeric[:NORMal]:ITEM1 URMS,3;
ITEM2 IRMS,3;...
(Set the numeric data items of element 3.)
:NUMeric[:NORMal]:VALue?
(Receive the numeric data of element 3.)
:NUMeric:HOLD OFF
• If :NUMeric:HOLD is set to ON after having
already been set to ON before, the numeric
data is cleared, and the most recent numeric
data is held internally. When retrieving numeric
data continuously, this method can be used
to circumvent the need to repeatedly set
:NUMeric:HOLD to OFF.
