DSI-110 System

 

1 kHz to 1.0 GHz

extendable to

 

100 Hz and 18 GHz

 with converters

 

 

 

 

Data

  

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.

 


 

R-110-40A Panoramic Display Unit




Data


The R-110-40A Pan Display provides a visual presentation of the receiver input frequency spectrum.

The unit features a large, easily viewed screen and an all analog implementation to minimize electrical interference.

 

R-150 Wide Range Receiver






Data

The R-150 receiver is a light weight, low power portable receiver with exceptional sensitivity and very low noise.

The R-150 tunes over a frequency range of 100 Hz to 1 GHz and includes 33 bandwidths from 50 Hz to 200 MHz in a modified 1:2:5 sequence.

The receiver includes AM and FM Demodulation, Pulse Stretch and Slideback controls, and an accurate
peak-reading DVM to measure video signal level and provide encoded data via the IEEE-488.2 bus.

The R-150 receiver will accept additional plug-in modules to enhance capabilities or to tailor the
receiver for particular applications.

The receiver can also be supplied in a portable configuration that includes collapsible side handles and a folding stand. Ears are available for rack mounting.

The R-150 may be used in conjunction with software
and a computer system for automated measurement and monitoring applications.

The R-1550B TEMPEST Receiver includes everything you need to operate from a frequency range of 100 Hz to 2 GHz. With options, the frequency range may be extended as low as 20 Hz or as high as 40 GHz.


 

The DSI-1550B TEMPEST Test Receiver is a PC based automated receiving system that permits precision measurements, test and analysis associated with surveillance. TEMPEST or EMI/EMC. The operation provides the user with manual and automatic receiver functions, and user friendly software that gives the user straight forward access to control sophisticated data reduction algorithms and displays. The standard DSI-1550B configuration,that Dynamic Sciences offers is an extensive library of software and hardware accessories that will allow tailoring of a system to specific applications.

Features:

  • Selectable Tuning Resolutions: Use the arrow keys below the display to select the tuning digit. The selected digit blinks. Use the step key to perform
    manual step tuning. The step size is determined by the selected digit. The tuning knob also tunes at the selected digit. Frequency Resolution is 0.1 Hz from 100 Hz to 250 kHz; 1 Hz from 250 kHz to 15 MHz; and 100 Hz from 15
    MHz to 2 GHz.
  • Synthesizer Design: Synthesizer design provides you with programmable frequency control. Any frequency may be entered from the
    keypad with up to seven digit resolution.
  • AM/FM Detector Switch: It automatically selects audio source. Gain controls are provided for headphone use.
  • Auxiliary Video Output: For Z-axis display; provides a direct connection for video monitoring use.
  • Z-Axis Output: Provided on the rear panel for “rastering” of repetitive signals. Automatic remote mode selection is provided by the
    host computer.
  • Low Noise Figure: The nominal noise figure is 6 dB. The noise floor in a 100 Hz bandwidth is -41 dB&#956V. The noise floor in a 10 kHz bandwidth is -21 dB&#956V. There is 80 dB image rejection over the entire frequency range. The noise floor will improve by at least 6 dB&#956V when the R-1550A Receiver is configured in the DSI-1550B TEMPEST Test System.
  • Preselection Filters: There are nine bandpass filters that may be individually selected during tuning corresponding with the receiver band
    and the tuned frequency. Filter values are 200 MHz Low Pass, 200-350 MHz, 350-550 MHz, 550-750 MHz, 750-1000 MHz, 1100 MHz Low Pass, 1.0 GHz-1.3 GHz, 1.3 GHz-1.6 GHz, and 1.6 GHz-2.0 GHz.
