Spectrum Manager Tool Description

Traffic Analyzer - The Scan*Star Traffic Analyzer uses high rate sampling to record measurements on one or more RF channels. Typical observation rates range from ten to forty per second, depending upon the receiver used. Measurements are integrated to produce air time, call count, signal strength average, minimum and maximum, and Erlang. Additional data elements are recorded to allow estimation of measurement errors. Data can be recorded in raw per-observation format or aggregated by hour in DBASE to facilitate later analysis. The raw format data can be tagged with accurate position and time using the optional GPS feature.

Band Occupancy Scope - The Band Occupancy Scope is intended to give a quick picture of channel usage in a frequency band. The Band Occupancy Scope sweeps through the selected band tracking the airtime for each channel in the band. The Band Occupancy Scope is intended to be a "front end" to the Traffic Analyzer. Use the Band Occupancy Scope to determine candidate channels for more detailed study with the Traffic Analyzer. The Band Occupancy Scope can perform the candidate selection process automatically, and create the necessary files to use with the Traffic Analyzer. Press the Traffic Analyzer Export button to start this selection process:

Signal Data Recorder - The Scan*Star Signal Data Recorder is used to collect air time and signal strength measurements on one or more channels. This tool is ideal for comparative measurements, power analysis, etc. Combined with the optional GPS features and the Signal Data Recorder becomes an excellent tool for coverage studies, "drive around" power and antenna measurements, etc.

Interference Correlator - This program is used to identify an unknown (frequency) signal that is causing interference on a known channel. Typically this program is used in tracking down intermod problems.

Trunking Data Analyzer - The Trunking Data Analyzer works with the Optoelectronics OptoCom. and analyzes trunking control channels. Activity and signal quality information are displayed. On Motorola systems, the TDA is useful for discovering the frequency plan for an unknown system. Information can be saved to a Scan*Star group file for later use in scanning. The Trunking Data Analyzer also includes a data logging feature for recording all control channel messages.

Conventional Scanning Tool - The Conventional Scanning Tool is used to scan a number of channels for monitoring. Scanning stops on active channels, allowing the channel to be monitored or recorded using the Digital Audio Logger or a tape recorder. A number of logging and alarm options are available, including PL, DPL, DTMF and GPS. Multiple frequency lists and ranges can be blended into a single scan list. The tactical display gives an "all in view" picture, allowing the user to adjust the scan list quickly. Up to ten radios can be scanned at the same time.

Band Scope - The Band Scope tool is used to graphically display the activity in a range of channels. An alert threshold can be set which can cause a number of actions to be triggered when a signal is received that exceeds the threshold. Alert actions include data logging, alarms, command execution and Digital Audio Recording.

Spectrum Analyzer - This tools graphically displays signal strength in a band. Point and click radio tuning can be used to investigate unknown signals.

Digital Audio Logger - Using a PC sound card, received audio can be recorded to the hard disk. All sound bites are tagged with the frequency, PL/DPL, time, date and other channel information which is embedded in the data file along with the digitized audio. Tagged information is reproduced during playback. Compression is used to reduce the amount of hard disk space required.
