The Invisible Waves model IW1800 is a 100KHz to 1.8GHz, PC-Based RF Spectrum Analyzer. As possibly the world's first PC-based, broad spectrum RF analyzer, the IW1800 touts some very unique features that go beyond the bounds of traditional RF analyzers. Though many of these unique features are well suited for wireless professional audio production and AV integration, the IW1800 is also the perfect tool for general commercial and industrial RF work. Below are a few of the IW1800's more unique features and functions.

White Space & Frequency Space Finder

The White Space Finder is an Open Space, Frequency Finder and Calculator. The user simply defines the open space required (bandwidth), the spacing between adjacent channels (band-guard), and a minimum threshold level. The open spaces are then graphically displayed in a priority order of largest open RF spectrum to smallest. It's perfect for locating open frequency space in crowded RF environments, or to help insure proper spacing for frequency coordination.

Monitored Frequencies

This feature provides priority status monitoring of user specified frequencies. Working completely independent of the sweep functions, Monitored Frequencies allows up to 10 frequencies to be custom labeled and viewed in a barograph, relative level format. The user can assign a specific threshold level in dbm, and anytime the signal falls below the threshold, the barograph level falls and changes from the color green to red. It's perfect for monitoring important transmitters such as a lead vocalist's, or to keep tabs on wireless guitars and remote control devices.

ROI Trace View

Region Of Interest (ROI) Trace View is an adaptation of a Zoom function, where the user can have both a standard sweep screen open, and an important Region Of Interest sweep. This feature allows the user to monitor a general broad RF spectrum range and simultaneously monitor a smaller frequency range. It's perfect for general RF analysis where comparative analysis or the ability to have two sweeps active at the same time is required.

Heat Map

The Heat Map, also called a waterfall graph, provides a color-based visualization of the RF level and activity over time. As signal levels for specific frequencies or frequency ranges increase and decrease, the Heat Map varies its colors. This feature provides a quick glance back into the sweep history to identify aberrations or fluctuation in frequency levels.

Scan Settings Control Panel

The Scan Setting panel allows the user to input specific Start and Stop frequency ranges, and/or a Center Frequency and Span. Based on the frequency span, the user can also choose from a selection of Resolution settings. Selecting the "Enable Peak Scan" enhancement algorithm instructs IW to inspect the results looking for potential peaks and, if any are found, rescans those particular frequencies at a finer resolution in order to obtain a more accurate signal strength reading. Also within this control panel is the user-defined Custom Profiles recall. Simply open the Profile control and use the pull-down feature to provide instant access to the custom set profiles.

Sensitivity Control Panel

The Sensitivity panel allows for the selection of Automatic or Manual Gain Control, RF Input Preamp On/Off and RF Input Attenuation.

Scaling Control Panel

The Scaling Threshold setting allows the user to define the scale in dbm. The Scaling control only affects the actual visual display. Also within the Scaling control panel is a Heat Map sensitivity control.

White Space Finder Control Panel

The White Space Finder panel allows the user to define a threshold level, at which lesser signals will be ignored and considered non-interference and non-threatening. The user can input the open space required and the spacing between adjacent channels. There is also a click-on box which calculates and equally spreads-out the open spaces in the chosen spectrum.

Data Recording Control Panel

The Data Recording panel features a simple, yet powerful, Data Recorder. Recorded data can be reloaded into the software for future evaluation and review. Included in the Data Recording control panel are Start Time, Recording Time, Number of scans recorded and the file size
