User area: 1.44Mbyte (2HD) or

720Kbyte (2DD)

File types:

Auto start program file, initial setup

file, measurement setup file, mea

surement setup/result file, stress

setup file, customize file, hard copy

data file, and Instrument BASIC

program and data file.

Format of data made by the HP BASIC

program:

Data made by the HP BASIC program

and data made by the Instrument

BASIC program are compatible.

Network mass storage device:

An NFS mountable mass storage device

File types:

Auto start program file, initial setup

file, measurement setup file, measure-

ment setup/result file, stresS setup

file, customize file, and hard copy

data file.

Maximum number of files allowed per

directory on network mass storage

device: 199

Data storage (supplemental data):

2HD DOS format:

Available bytes: 1457K (byte)

File size:

Measurement setup: 3843 (byte)

Stress setup: 601 (byte)

Measurement setup/result

(Typical data): 15387 (byte)

(VAR1: 101, VAR2: 5)

Repeating and Automating

Test

Instrument Control

Agilent 4155C and 4156C function

control:

Internal or external computer controls

the 4155C and 4156C functions via

the GPIB interface

Command sets:

SCPI command set

Agilent FLEX command set

Agilent 4145B command set

Program Memory:

Using the Agilent FLEX command set,

the user can store program code in

the 4155C or the 4156C. The maximum

number of subprograms is 255 (8 bit).

External instrument remote control:

Control external equipment via the

GPIB interface.

Instrument BASIC

Instrument BASIC is a subset of

HP BASIC.

Functions:

Arithmetic operation, binary opera

tion, string manipulation, logical

operation, array operation, program

flow control, event-initiated branch

ing, program editing and debugging

support, mass storage operation,

instrument control, real-time clock,

softkey operation, and graphics.

Agilent 4145B automatic sequence

program (ASP) typing aid:

4145B ASP-like syntax softkeys are

available in instrument BASIC. A

4145B ASP file cannot be read by

the 4155C or 4156C.

Remote control:

Instrument BASIC is remote

controllable from an external

computer via the GPIB interface.

Instrument BASIC memory area

(supplemental data):

Program (text) area: 16K (byte)

Variable/stack area: 500K (byte)

Common variable area: 600K (byte)

Note: The memory size for common variable is

decreased when hard copy or disk operation is

performed.

Trigger

Input:

External trigger input starts a sweep

or sampling measurement or can be

used as a trigger input for continuing

an Instrument BASIC program.

Input Level:

TTL level, negative or positive edge

trigger

Output:

External edge trigger outputs can

be generated by the start of a sweep

measurement, the start of each

sweep step in a staircase sweep, the

start of each pulse leading edge for

an SMU in pulse mode, and the

issuance of an an IBASIC trigger out

command execution. In addition, you

can set the trigger signal to be active

during the Stress Force State. If you

have a 41501A/B with PGU option,

you can output a synchronized

trigger output through the 41501A/B

trigger output.

Output Level:

TTL level, negative or positive logic

4145B Data Compatibility

and Syntax Commands

Setup and data file

Measurement setup and data from the

4145B can be loaded.

GPIB program

GPIB programs for the 4145B can be

used when the 4145B command set is

selected.

Note: There is a possibility that GPIB programs

for the 4145B will need to be modified.

Interfaces

GPIB interface:

SH1, AH1, T6, L4, SR1, RL1, PP0,

DC1, DT1, C1, C2, C3, C4, C11, E2

Parallel interface: Centronics
