DSI-110 System
1 kHz to
1.0 GHz
extendable to
100 Hz and 18 GHz
with converters
|
|
The DSI-110 integrates either the R-110 or R-110B Receiver with a
sophisticated data acquisition and measurement software package and
off-the-shelf computer hardware to yield a powerful and versatile RF
measurement and reporting system.
The DSI-110 is ideally suited to a wide variety of signal measurement
tasks in either laboratory or field environments, including EMI/EMC
testing, RF instrumentation, spectrum surveillance, and remote signal
monitoring.
The
R-110 and R-110B receivers cover a wide frequency range (1 kHz to 1
GHz), permitting LF through UHF detection with a single receiver. Both
receivers feature excellent noise figure and dynamic range
characteristics, spur-free operation, and a large number of bandwidths
to facilitate signal capture in the presence of high ambient noise.
The system software operates in the Windows 3.1x environment; it is
exceptionally flexible and easy to learn and use. The software is mature
and is compatible with fixed and removable-cartridge disk drives,
printers, plotters, and other peripherals. Various ancillary software
routines are available which tailor the system to particular
applications, such as frequency management and spectrum surveillance.
The R-110 and R-110B receivers are designed to facilitate expansion, and
both accept plug-in modules to enhance their inherent capabilities. The
R-110B is fully augmented with wide-bandwidths, FM demodulator,
pulse-stretch and slideback, DVM display, and bandwidths in a 1:2:5
sequence. Ancillary units provide panoramic display, frequency extension
to 100 Hz and 18 GHz, and calibration with impulse and comb generators. |
