Programming Overview
The HP 4155A/56A can be fully controlled from an external computer or
by using built-in HP Instrument BASIC (IBASIC) controller.IBASIC is a
programming environment that allows full control of HP 4155A/56A without
using an external computer.
To fully control the HP 4155A/56A, you execute programs that contain SCPI
commands. SCPI means Standard Commands for Programmable Instruments.
SCPI is the default program language of the HP 4155A/56A, and can control
all functions of the HP 4155A/56A. These programs can be run from IB
ASIC
or an external computer.
The HP 4155A/56A has two command modes:
 HP 4155/56 command mode is the default mode of HP 4155A/56A.
You use this mode in all cases, except when directly running an HP
4145A/B program. In this mode, you can use a program that contains SCPI
commands, which allow you to control all functions of the HP 4155A/56A.
 HP 4145 syntax command mode , which allows you to execute HP 4145A/B
programs on the HP 4155A/56A directly with little or no modication. In
this command mode, you cannot control all functions of HP 4155A/56A.

How to Migrate HP 4145A/B Programs
HP 4145A/B Auto Sequence Program (ASP) programs run on the HP 4145A/B built-in programming
environment and allow basic control of HP 4145A/B without using an external computer.To run the
ASP programs on the HP 4155A/56A, you do one of the following and execute the program in the HP
4155/56 command mode :
 Create a program that performs the same operations as the desired ASP program by using the
IBASIC editor typing aid softkeys to enter commands that correspond to each ASP command. This
program can run on IBASIC only, not on an external computer. Refer to \Creating ASP-like IBASIC
Programs" in Chapter 1 for details.
 Create a program using SCPI commands that performs same operations as the desired ASP
program. This program can run on IBASIC or on an external computer
. Refer to \Programming
Example for HP 4145 Users" in Chapter 4 for details.
HP 4145A/B HP-IB programs run on an external computer and allow full control of the HP 4145A/B.To
run these programs on the HP 4155A/56A, do one of the following:
 Directly run the HP 4145A/B program on the HP 4155A/56A with little or no modication. Y
ou
must run this program in the HP 4145 syntax command mode from IBASIC or an external
computer. Refer to Chapter 5 for details.
 Create a program using SCPI commands that performs same operations as the HP 4145A/B
program. You must run this program in HP 4155/56 command mode from IBASIC or an external
computer.

Using HP Instrument
BASIC

Using HP Instrument BASIC
HP Instrument BASIC (IBASIC) is a system controller built into your
HP 4155A/4156A. By using IBASIC, you can run a program to control
the HP 4155A/4156A and other instruments (connected via interfaces of
HP 4155A/4156A) without using an external computer.
IBASIC is a subset of HP BASIC. Programs created by IBASIC can run on an
HP BASIC controller with little or no modication.
This chapter consists of the following ten sections.
The following six sections provide step-by-step instructions to operate
IBASIC by using examples.You can learn the basics of IBASIC programming
and operations. If you are not familiar with IBASIC, we recommend to read
through these sections rst.
 Before Operating IBASIC
 Creating and Executing a Simple IBASIC Program
 Modifying Program by using Editor Functions
 Saving and Getting a Program
 Summary of Softkeys and Keyboard Operations for Editor
 Other Basic Features of IBASIC
The following three sections are a task oriented reference for IB
ASIC. You can
quickly nd the desired IBASIC task.
 IBASIC Basic Operation Tasks
 IBASIC Editor Tasks
 Control from External Computer
The following section introduces how to easily create a program by using the
typing aid softkeys in the IBASIC editor. This method of creating a program
is similar to using the ASP environment on the HP 4145A/B semiconductor
parameter analyzer.
 Creating ASP-like IBASIC Programs

Before Operating IBASIC
HP 4155A/4156A provides the following three screen modes for operating
IBASIC.
\All IBASIC"
screen
Entire screen including softkeys is used for IBASIC, so no
instrument page is displayed.
You can execute programs, but no instrument page
appears in this mode.
\IBASIC Status"
screen
Softkeys and bottom two lines are used for IB
ASIC. Rest
of screen is for instrument page.
In this mode, you can start the IBASIC editor. The
displayed softkeys are for IBASIC operation. You can
execute IBASIC commands interactively. Characters you
type are displayed at the bottom of the screen.
\All Instrument"
screen
.This is regular instrument screen and the default display
mode at power on. Entire screen is for instrument page
,
and all softkeys are for interactive use of instrument. In
this mode, you cannot use the IBASIC editor. Only the
front-panel keys of IBASIC key group and 4
Ctrl
5 + 4
U
5 (Run)
and 4
Ctrl
5 + 4
P
5 (Pause) on external keyboard are available
to execute or pause program for HP Instrument B
ASIC
from this screen mode.
For details about HP Instrument BASIC screens, refer to \IBASIC Screen"in
