Programming: Data Transfer

To Transfer Data to HP 4155A/4156A (Using User

Variable)

To transfer a user variable to HP 4155A/4156A, use DATA

TRACe subsystem

commands. A user variable consists of a name, unit, and numeric data.

Transferred user variable data can be used like other data variables in HP

4155A/4156A. You can perform calculations between measurement results

and transferred data, plot transferred data on GRAPH/LIST: GRAPHICS page,

or list transferred data on GRAPH/LIST: LIST page.

To transfer numeric data to the HP 4155A/4156A:

1. Dene the data transfer format by using :FORMat[:D

ATA] command.



For ASCII data transfer format, send

:FORM ASC



For REAL 64-bit length data transfer format, send

:FORM REAL,64



For REAL 32-bit length data transfer format, send

:FORM REAL,32

2. For REAL data transfer format, dene byte order by using

:FORMat:BORDer command.



For normal order, send

:FORM:BORD NORM



For swapped order, send

:FORM:BORD SWAP

3. Dene name of the user variable, unit (optional), and number of numeric

data by using the :PAGE:CHANnels:UVARiable:DEFine command.

You can also dene these parameters by using the :D

ATA:DEFine and

:DATA:UNIT command.

If user variable is already dened, you do not have to perform this step.

4. Transfer data by using :DATA

:TRACe:[:DATA] command.
