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.
Hard Copy via Network Interface
The network interface has lpr client
capability.

Graphics Hard Copy
Agilent 4145B automatic sequence
program (ASP) typing aid:
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
4145B ASP-like syntax softkeys are
available in instrument BASIC. A 4145B
ASP file cannot be read by the 4155C or
4156C.
Remote control:
Data storage (supplemental data):
2HD DOS format:
Instrument BASIC is remote controllable
from an external computer via the GPIB
interface.
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).
Available bytes: 1457 K (byte)
File size:
Instrument BASIC memory area (supple-
mental data):
Measurement setup: 3843 (byte)
Stress setup: 601 (byte)
Program (text) area: 16 K (byte)
Variable/stack area: 500 K (byte)
Measurement setup/result

Hard Copy File
Common variable area: 600 K (byte)
Note: The memory size for common variable is
decreased when hard copy or disk operation is
performed.
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.
