The PI 4100 is Potomac's third generation of precision survey instrumentation intended for the direct measurement of electromagnetic field strength in the 520 kHz to 5.1 MHz frequency spectrum. This instrument combines a laboratory quality radio frequency voltmeter, a calibrated, shielded loop antenna, an internal GPS receiver, an internal calibration source, and data acquisition hardware and software in a single rugged package weighing less than 3 kg.
This device is equipped with an embedded microcontroller engine that obtains measurement data from the various transducers within the instrument and formats that data for display and, at the option of the use, stores it to memory.
- 116 dB dynamic range tuned RF voltmeter
- Digitally synthesized tuning in 1.0 kHz increments
- Spectrum display to facilitate various compliance measurements (Field Strength, Harmonic level, and Spectrum Occupancy) in a single instrument
- Provisions for third party calibration - using their laboratory standards - when it is impractical to return the instrument to the manufacturer for calibration
- Data acquisition software and PC interface to enable the collection, analysis, and e-distribution of current field measurements. (This feature anticipates the future acceptance of data e-filing by federal regulatory agencies.)
