OPTOELECTRONICS SECURITY

The Digital Scout RF frequency recorder / field strength meter is the only instrument capable of counting pulsed RF (digital signals), as well as conventional CW (analog signals) from 10MHz - 2.6GHz.

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 also incorporates the Optoelectronics patented, Reaction Tune and the built-in RS232 port allows for the direct connection to a PC for real time datalogging and download of frequencies in memory.

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.

Digital Modulations

The Digital Scout has both conventional CW as well as pulsed RF frequency measurement capability. RF pulses or bursts as short as 300uS in duration can be measured using a new pulse slicing technique which accumulates data from successive pulses. RF pulses can be either uniform and repetitive or may vary widely in duty cycle and duration. Different types of modulation can be accommodated as long as zero crossings are produced by the RF carrier. Signals such as TDMA, GSM, Frequency Hopping Spread Spectrum (FHSS), APCO 25, ON/OFF Keying, TETRA, RF remotes, RC controllers and other pulsed RF are capable of being detected by the Digital Scout.

The Digital Scout is not capable of counting Direct Sequence Spread Spectrum (DSSS), CDMA and PCS.
