Audio Analyzer UPL 7
• Built-in hard disk and disk drive
• Connectors for keyboard, mouse,
monitor, printer and plotter
• Centronics interface for connecting
printer or network
• Drivers for commercial printers are
supplied as standard
• Remote control via IEC/IEEE bus or
RS-232-C interface
• Postprocessing of results directly in
UPL using standard software
• All results available in the common
data formats, making it easy to im-
port graphics into documents, for
example
• Easy loading of function and soft-
ware extensions via floppy disk
• Automatic test sequences and mea-
surement programs with universal
sequence controller. Easy genera-
tion of programs with built-in pro-
gram generator Audio Analyzer UPL is a compact unit
with an integrated controller. It avoids
the disadvantages of external PC con-
trol, which is found in other audio ana-
lyzers.
The instrument is easy to transport as it
requires no external equipment such
as keyboard, monitor or other PC
peripherals.
UPL is supplied ready for use. Installa-
tion is nothing more than unpacking
the unit and switching it on for starting
the measurement. The user is not bur-
dened with problems that cropped up
in the past with the installation of inter-
face cards or PC software.
With audio analyzers controlled from
an external PC, interference may be
radiated from the PC, monitor or inter-
face connections, which distorts mea-
surement results. Not so with UPL: the
instrument has specified EMC charac-
teristics which also include the internal
PC. In contrast to conventional PCs,
UPL features elaborate screening such
as magnetically shielded power trans-
formers and coated filter pane in front
of the display.
And a real boon: the price of UPL
includes the internal PC.

The strengths of UPL
show up especially in
mobile use. The unit is
compact and light-
weight and requires no
additional equipment.
Results are stored in the
built-in PC and thus
available for later use.
Routine measurements
can be repeated easily
using stored instrument
