LBA's EMFaraCage® faraday cages are EMI and RFI shielding boxes and RF test enclosures that bring convenience to device testing. Faraday cages are ideal for isolating critical systems in high field RF environments or wherever RF ingress or egress must be minimized. Security, production testing, biomedical research and semiconductor testing are only a few of the many areas where EMFaraCage® faraday shielded enclosures are employed. EMFaraCage® faraday cage enclosure systems are fully featured to support a wide variety of test missions. The standard faraday cages include effective power, dataline and RF signal isolation in large test volumes. EMFaraCage® faraday cages are much more affordable than shielded room solutions and offer the convenience of portability.

Near-Field Probes 100 kHz up to 50 MHz
LF1 set
-
The LF1 near-field probe set consists of 4 shielded near-field probes used during the development process for emission measurement of longwave, medium wave, and shortwave frequencies on electronic devices. The probe heads of the LF1 set are designed for incremental detection of sources of electromagnetic interference on assemblies. First, the electromagnetic interference of the assembly is detected by the LF-R 400 probe from up to 10 cm. Then probes with higher resolution like the LF-B 3, LF-U 5 and LF-U 2.5 are used to more precisely detect any source of interference. The probe heads are designed for taking measurements at single pins and larger components. Near-field probes are small and handy. They have a current attenuating sheath and, therefore, are electrically shielded. They can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. The H-field probes do not have an internal terminating resistance of 50 Ω.

IsoVu Isolated Probes
-
The IsoVu Measurement Systems can make nearly impossible measurements – like high-side Vgs- a reality, providing today’s power engineer with measurement insights not available in other power systems and instruments. When performing near-impossible measurements, especially in those involving Gallium Nitride (GaN) and Silicon Carbide (SiC), it can be extremely time consuming and cumbersome. IsoVu eliminates those concerns: IsoVu probes offer better common mode rejection and higher bandwidth for high EMI environments and on power FETs like SiC and GaN.

Inverters
-
Analytic Systems has been producing Pure Sinewave Inverters since 1994. Originally designed for running navigation computers on commercial and fishing vessels, the line has evolved into a range of models with power outputs from 300 to 3600 watts featuring Digital Signal Processor control. High power MosFet technology creates a low voltage Sinewave that is fed into a compact toroidal step-up transformer to produce a very clean low EMI AC output. Northrup Grumman evaluated inverters from all major manufacturers and chose the IPSi series by Analytic Systems for their Army portable command centers for precisely this reason.
