Automatic Analysis Function
On a graphics plot, the markers and lines
can be automatically located using the
auto analysis setup. Parameters can be
automatically determined using automatic
analysis, user function, and read out
functions.
User Variable
Display the data on the LCD via GPIB or
instrument BASIC.
Output
Display
Display Modes
Graphics and list.
Graphics Display
X-Y or X-Y1/Y2 plot of source current/
voltage, measured current/voltage, time,
or calculated USER FUNCTION data.
List Display
Measurement data and calculated USER
FUNCTION data are listed in conjunction
with VAR1 step number or time domain
sampling step number. Up to eight data
sets can
be displayed.
Display
8.4-inch diagonal color active matrix LCD,
640 dot (H × 480 dot (V). More than 99.99%
of the pixels on an LCD are active.
Hard Copy Functions
Graphics Hard Copy
Measured data and all data appearing on
the LCD can be output via GPIB, parallel
printer port, or network interface to
supported HP plotters or printers. PCL,
HR PCL (high-resolution PCL), and HP-GL
formats are supported (selectable).
Text Hard Copy
Print out setup information or measured
data list as ASCII text via GPIB, parallel
printer port, or network interface to
supported HP plotters or printers. PCL,
HR PCL, and HP GL formats are supported
(selectable).
Hard Copy File
Hard copy output can be stored to an
internal or external mass storage device
instead of sending it to a printer or plotter.
The data can be stored in PCL, HR PCL,
TIFF, HR TIFF (highresolution TIFF), or
HP GL formats.
Hard Copy via Network Interface
The network interface has lpr client
capability.
High-Resolution (HR) Mode
This fi le mode is available for cases where
an extremely clean print-out or plot is
desired.
Note: High-resolution mode takes signifi cantly greater
CPU time to generate, so its use is recommended for
fi nal reports only.

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 operation,
string manipulation, logical operation,
array operation, program fl ow control,
event-initiated branching, 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 fi le 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 (supple-
mental data):
Program (text) area: 16 K (byte)
Variable/stack area: 500 K (byte)
Common variable area: 600 K (byte)
Note: The memory size for common variable is
decreased when hard copy or disk operation is
performed.
