Ultraview Corporation
14-bit 16-concurrent channel 65MSPS A/D board for demanding large-system uses, where signals on multiple time-aligned channels need to be observed with high SNR, such as RADAR, nuclear instrumentation, ultrasound, medical imaging, spectroscopy, communications systems, RF component and antenna testing and other critical applications. An on-board low-jitter LMX2581-based RF synthesizer allows any A/D sampling rate between 20MSPS and 65MSPS to be specified in software. A second on-board LMX2581 with synchronized reference can be optionally used to output four stimulus clocks on SMA connectors that can be vectored to any combination of 4 external transmitters, microwave pulse generators, laser modulators, and other devices.

Tuned half-wave dipoles have been among the most important antennas from thebeginning of rf-technique. The characteristics of half-wave dipoles havebeen calculable very early using the Maxwell and Hertz equations. Therefore the halfwave dipole became a reference antenna. The ideal (lossless) half-wave dipole has anisotropic gain of 2.15 dBi and an impedance of 73 Ohm. The directional pattern is circular inthe H-plane, "8-shaped" in the E-plane with the maxima perpendicular on the dipole axis.The half-power beamwidth (-3 dB) is approx. 78°. The impedance of real dipoles isdepending on the thickness/length ratio of its elements, typical values are 60-70 Ohm.Dipoles for industrial applications are available in the frequency range from 30MHz to up to approx. 4 GHz. The dipole elements are length variable (telescopic) orwith fixed length, the latter especially above 1 GHz. The most important applications aretest site evaluations (NSA, normalized site attenuation) and the determination of ERP(Effective Radiated Power) respectively EIRP (Effective Isotropic Radiated Power).

COMM-connect
SWR True Antenna Analyzer is a versatile analyzer covering all major communication bands from 30MHz to 2700MHz. The SWR True will analyze antennas and cables. Measurements are represented graphically as VSWR or Return Loss plots. The built in PLL synthesized generator offers a superior accuracy with small step size. The internal operating system controls measurement, display and the I/Os allowing serial communication to PC, USB to memory stick and USB Serial communication. The I/O options are used to write plots to either memory sticks or to a connected PC, the I/Os can also be used to operate the instrument, giving commands and receiving data. For documentation reference the instrument has a real time clock. Multilayer menus are used to setup and control the operation of parameters. The SWR True instrument is small, handy and light weight battery operated with more than 6 hours of continuous operation on the internal NiMh cells. Feature with XML data handling and application viewer is included. Accessory kit with soft carrying bag, car charger and coax adapters for standard types.

Com-Power Corporation
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.
