Controlling Instrument B ASIC From an External Controller
The E5100A/B has a command called the Program Subsystem command that enables an
external controller to control Instrument B ASIC. The program subsystem command enables you
to execute a program written in Instrument B ASIC or refer to the variables used by Instrument
B ASIC from an external controller . This section will describe the following topics related to the
program subsystem command usage .

Remote Processing a B ASIC Command
Transferring a Program
Note
The following commands and programs are all executed on an external
controller .
Note
The program subsystem command is based on SCPI (Standard Commands for
Programmable Instrument).
Referring to and Transferring an Array
Y ou may need to exchange data between programs when you are using an external controller
and Instrument B ASIC together . This section describes how to use the program subsystem
command to exchange data.
Referring to a Numeric V ariable
Execute the following statements to refer to numeric variable data in Instrument B ASIC from
an external controller:
OUTPUT @E5100;"PROG:NUMB? 'Dat'"
ENTER @E5100;Dat
Module 6-5. Referring to a Numeric V ariable
Referring to a String Character V ariable
Similarly , refer to a string character variable as follows:
OUTPUT @E5100;"PROG:STR? 'String$'"
ENTER @E5100;String$
