The new Digital Scout RF frequency recorder / field strength meter is the second in a line of nearfield instruments capable of counting digital signals, as well as analog signals. Until now, the only signals that a frequency counter could lock onto were analog signals. In addition to locking onto digital and analog signals, the Digital Scout has a calibrated signal strength measurement from -45dBm to -5dBm.
The Digital Scout is capable of detecting many different types of digital modulations that have a minimum pulse width of 500uS, signals such as TDMA, GSM, APCO 25, ON/OFF Keying, TETRA and more. Spread Spectrum modulation (CDMA) has shorter pulse widths than 500uS, therefore the Digital Scout is not capable of detecting those signals.
Another breakthrough feature of the Digital Scout is the calibrated field strength measurement provided on the two line LCD display. The Digital Scout displays field strength in dBm with a signal strength bargraph serving as a reference. The Digital Scout reads and displays signal levels from -45dBm to -5dBm with an accuracy of +/- 5dBm. This feature is great for checking nearfield RF levels at remote sites, locating hidden transmitters, determining power levels from two-way radios and more.
The Digital Scout incorporates the patented Optoelectronics feature, Reaction Tune. In Reaction Tune mode the Digital Scout captures a frequency and automatically tunes a compatible receiver to that frequency. This allows the user to instantly monitor the audio of the captured signal (analog signals only). Those receivers compatible with the Digital Scout for Reaction Tune are as follows.
ICOM IC R10, R7000, R7100, R8500, R9000. AOR AR8000 and AR8200. BC245XLT and BC780. OPTOELECTRONICS Optocom, Os456/Lite, OS535 and R11
The Digital Scout has a built-in CI-5 interface that can be used to interface to the Optoelectronics Optolinx for downloading frequencies saved to memory. This interface allows for direct connection to the Optolinx which in turn interfaces directly to serial port on a PC.
The Digital Scout has a unique way of displaying the frequency measured. Like most conventional frequency counters, the Digital Scout will display the actual measured frequency coming from a transmitter, such as 454.1247. However, the Digital Scout can also display the actual channel frequency of the transmitter, such as 454.1250. This is especially useful to the two way radio professional when programming new radios.
