General characteristics
Mainframes: See table 72 on
page 56.
Save/recall: Pattern segments,
settings and complete settings
plus segments can be saved and
recalled. The number of settings
that can be stored is limited only
by disk space.
Vector import/export: File format is
ASCII using a STIL subset.
Import/export to/from ParBERT
internal data-base for regular file
transfer via USB memory stick, CD
or LAN is handled by ParBERT
user SW. Direct programming of
data segments is possible via
GPIB (IEEE 488.2) and SCPI.
Programming interface: GP-IB
(IEEE 488.2) and LAN. The
interface to applications such as
C, Visual Basic, or VEE must be
installed. Use the Agilent 81200
Plug&Play drivers for easy
programming.
Programming language:
SCPI 1992.0, active X for MUI
Programming times: Vector transfer
from memory to hardware
depends on the amount of data.
See Table 70 for examples.
On-line help: Context-sensitive.
Print-on-demand: Getting started
and programming guides can be
printed from .pdf files included
in the ParBERT 81250 software.
Self-test: Module and system
selftests can be initiated.
