Handheld or Benchtop Usage & Data Logging

The V4 Series of handheld EMF analyzers offers the unique ability to perform complex test and measurement in the field without lugging around bulky, expensive, outdated equipment that could get damaged, stolen, or worse – cause injury to the engineers that must carry it around! That does not mean that the NF 3000 series is only valuable for field applications, however. Used in conjunction with the included PC software, these portable and rugged handheld units easily transform into a full-featured bench top spectrum analyzer, complete with remote PC-based control, and extended data logging and playback. The PC software is capable of controlling multiple AaroniaUSA V4 units, making it extremely easy to switch between several analyzers to perform extensive testing in multiple locations and multiple pre-determined frequency ranges, without ever leaving your seat. Each handheld unit also includes internal memory for field-based data logging (up to 100 logs – optional upgrades available), and playback and analysis in the PC software interface after taking field measurement.

Pre-Programmed Hot Keys and Pre-defined Profiles

Each analyzer features 10 Hot Keys that can be programmed to meet your exact frequency ranges and specifications. Re-programming these hot keys is an extremely easy process that takes less than 5 minutes, and is detailed thoroughly in the provided user manual. Like everything about the Spectran V4 line of analyzers, customization is as user friendly as possible.


The handheld unit is controlled via button-press interface, pre-programmed hotkeys, multi-function jog dial, or remote controlled via USB / PC software. The unit includes an internal 1300 mAh battery offering 2 hours of autonomous run time. Expanded batteries (3000 mAh LiPo) are available. The Spectran V4 series of handheld EMF analyzers offers both an internal Helmholtz 3-axis sensor and internal E-field antenna or via the external input, conveniently housed in a lightweight and durable handheld analyzer unit.

1MB Internal Memory Expansion (Option 001): Provides an upgraded 1MB internal memory for extended field-based data logging; standard factory install memory offers up to 100 logs – expanded memory increases to over 10,000 logs.

3D Geomagnetic / Static Sensor (Option 006): Provides 3D Isotropic measurements of Earth’s magnetic field or static magnets. NF 5000 series only.

24 Bit Resolution (Option 009): Only for use with Option 006 3D Geo / Static Sensor, offers ultra high resolution on static magnetic fields. NF 5000 series only.

20MHz Frequency Expansion (Option 008) and 30MHz Frequency Expansion (Option 010): Expands the high end of the analyzer’s frequency range to 20 / 30 MHz. NF 5000 series only.

Docking Station: High-quality docking station/analyzer stand for benchtop use, with integrated connectors (USB, SMA).

GPS Logger: This optional GPS logger offers 6 sensors (GPS, Gyro, 3D Tilt, Digital Compass, Height, and Accelerometer) and integrates with the analyzer directly to pinpoint locations. This is ideal for automatic for recording field measurements and generating heat maps (with Google Maps, for example), as well as visualization of network coverage for GSM, WLAN, etc.

Broadband Antennas: Spectran V4 Analyzers are fitted with high-quality SMA connectors that allow them to interface directly with our full line of precision broadband antennas, including directional LP antennas, low-frequency magnetic field tracking antennas, and omnidirectional radial isotropic antennas. These antenna models are available in optimized frequency ranges, and come in many varieties to suit countless RF analysis applications.

External Low Noise Pre-Amplifiers: Spectran V5 Analyzers also interface directly with our full line of external battery-powered LNA, to heighten sensitivity up to -170dB and sniff out extremely weak signals.

Near Field Probe Set: Available in passive and active models, AaroniaUSA near field probe sets offer 5 probes with or without 40dB preamplifier, to sniff out weak signals in near-field EMC testing applications.

Cables and Connectors: AaroniaUSA offers a wide variety of compatible cables and connectors, including 1 meter, 5 meter, and 10 meter SMA cables, DC blockers to prevent the 50 Ohm SMA input from being destroyed by DC voltages, 20 dB attenuator to expand the measurement range to 33dBm, SMA-SMA connectors, SMA-N connectors, and more.

Protective Rubber Boot: Durable rubber boot protects handheld analyzers from drops, falls, and crushing, making your already durable handheld analyzer even more protected from heavy-duty applications.
