External Pre-amplifiers
-
Although all Spectrum A/D cards have a very powerful input section with a highly configurable input amplifier and a variety of input ranges it is sometimes necessary to have additional external amplifiers if the signal to acquire has an extremely low level. Spectrum offers a range of perfectly matching external amplifiers to cover such cases. These powerful amplifiers have been rated using the Spectrum cards and offer best performance together with high amplification rates.The amplifiers are simply connected between the signal source and the Spectrum A/D card input and can be manually switched between different settings using small lever keys. All amplifiers allow the offset compensation by using an adjustable screw.

Emissions Test System
PC-114
-
Perform Radiated & Conducted EMI pre-compliance testing at your facility up to 1 GHz. Com-Power PC-114 EMI emissions test system is a ideal solution performing pre-compliance EMC testing from 9 kHz - 1 GHz.. It has essential equipment needed for radiated and conducted EMI emissions measurements. The system includes a spectrum analyzer, antennas, near field probes, a preamplifier, LISN and a non conductive antenna tripod. Pre-compliance testing in EMC is a commonly used term not easy to define. In general, it implies testing done prior to formal testing for legal compliance. Formal legal compliance is performed at a facility designed and equipped with test instrumentation that is fully compliant with the applicable EMC standards. Such facility and instrumentation is capital intensive and can be expensive even to rent and not easily available. Compliance testing is performed per exacting requirements of the Standards and other reference documents adhering to the test methods and last detail. In addition, the test facility may require to be accredited by an accreditation body such as NVLAP, A2LA. Often it is desirable to know prior to compliance testing at such facility, whether a product is close to compliance and also how close. Pre-compliance testing is specially useful for specifications such as FCC, Part 15, EN 55022 or EN 55011 (CISPR 22 or CISPR11). Pre-compliance testing usually means using the full compliance methods but making a few educated compromises in use of site or equipment to reduce costs and testing time. Here are some benefits of pre-compliance testing.

ELT STALKER Vector-finder
VF-121
-
The Vector-Finder Types VF-121 and VF 121A are unique in the Vector-finder series of direction finding antennas. They incorporate a proven design, electro statically shielded loop sensing element with modern solid state low noise analog and digital technology to allow detection and location of aircraft band signals. Both the VF-121 and the VF 121A incorporate a unique digital modulator which allows the user to more easily home-in on unmodulated carriers. Such cases occur at airports when transmitter may be accidentally keyed on during aircraft overnight layovers. The VF-121 is specifically designed to be used on airport premises where signal strengths are high. To compensate for very strong signals, an integral attenuator is also incorporated to allow the user to operate the unit close-in to aircraft. The VF-121A differs in that a high gain, low-noise preamplifier is utilized with the sensing element in order to hunt signals that may be weak or at a distance. The unit is ideally suited for the location of ELT transmitters in the field. Both units are tunable over the 118 MHz to 130 MHz aircraft frequencies and interface directly to the user’s aircraft band receiver or transceiver via the antenna jack. With the antenna system connected to the receiver, the user will hear the desired signal. If the signal is unmodulated, the digital modulator will generate a tone on the carrier. When the handheld unit is rotated about, an audible null on the received signal or the generated tone will be heard. This null aligns with the axis of the equipment case and represents the direction of the received signal. This direction may be read from the black dial compass mounted on the top of the enclosure. As the response is bi-directional, triangulation may be used to determine the true bearing when the true direction is not known.
