Passive Intermodulation (PIM) occurs when multiple RF signals encounter defects in materials or workmanship in an RF path. These defects behave like a mixer causing noise to be generated at mathematical combinations of the original carrier frequencies. PIM interference that falls in the receive band of a wireless system elevates the noise floor resulting in high dropped call rates, call blocking, slow data transmission speeds and decreased system capacity.Kaelus is the industry leader in Passive Intermodulation test solutions. Since 1996 Kaelus has supplied RF equipment manufacturers around the world with precision IEC compliant test equipment to perform this critical test. From initial product design through high-volume manufacturing, Kaelus offers a wide range of PIM test solutions that enable equipment manufacturers to quickly and confidently verify the performance of their products.

S95090B -
Keysight Technologies
The S95090B spectrum analyzer (SA) measurement software adds high-performance microwave spectrum analysis to PXI VNAs. With fast stepped-FFT sweeps resulting from optimized data processing, the SA software application provides quick spurious searches over broad frequency ranges. The S95090B software uses the PXI network analyzer's test and reference receivers to complete simultaneous spectrum measurements. Multi-channel SA measurements leverage the PXI VNA's internal swept-signal generators for efficient measurements of spurious signals emanating from mixers and frequency converters. The S95090B spectrum analyzer software application employs source-power and receiver-response calibration as well as fixture de-embedding, providing in-fixture and on-wafer spectrum measurements with the highest level of accuracy. Optional external attenuators should be connected with the VNA’s test ports to avoid receiver compression when measuring large signals.

Konica Minolta Sensing Americas, Inc
Instrument Systems brings you a selection of exciting turnkey systems for use in evaluating display characteristics. It allows for the easy measurement of different spot sizes due to the variety of interchangeable lenses. Instrument Systems display measurement products are extremely responsive and produce highly precise results. Like many of the Instrument Systems products, they work well in collaboration with each other. These advanced systems are based on several display measurement instruments including the Spectro 320 and CAS140 CT spectroradiometers and our leading telescopic optical probe, the TOP 200. The TOP 200 is primarily used for work in panel graphics and display testings. It measures radiance and luminance intensity, delivering images spots in perfect round shapes, unlike competitor products which are prone to blurring and imperfect elliptical shapes. Instrument Systems can guarantee TOP 200’s low polarization and reproducible results due to their patented mode mixer which is incorporated into the optical fiber connection. No matter what type of display measurements you require, Instrument Systems can provide a setup that goes beyond your expectations.

FB7-NX -
National RF, Inc
In about 1935, the National Radio Company of Malden, Mass., brought out a “hot” high frequency receiver, called the FB7, and the subsequent FB-7X. It featured a super-hetrodyne design with plug-in coils that gave it a broad frequency range. The “X” model also incorporated a crystal filter in the intermediate frequency section, thus giving it additional selectivity. The receiver was viewed by radio amateurs as a technological breakthrough, and it was also used commercially for point to point high frequency communications. As the receiver did not have an internal RF amplifier section, a separately tunable RF amplifier was later provided in a separate enclosure for additional performance capabilities. Now, National RF, Inc., is resurrecting the fabled receiver name with an all solid-state, hot mini receiver, which also utilizes plug-in coils to cover the HF spectrum. The mini-receiver is designed for use by radio amateurs as well as serious short-wave listeners, and allows reception of AM, CW, and SSB signals. It incorporates a super-hetrodyne design with a dual gate FET built-in RF preamplifier and a ceramic filter for selectivity, often required when used in a crowded amateur radio band. In addition, the receiver has a buffered rear panel output of the high frequency oscillator for use with either a frequency counter for exact receive frequency display, or for interface with an outboard transmitter. A rear panel jack is also provided for muting the receiver when a transmitter is placed into the transmit mode. And, the receiver is small enough to fit into carry-on luggage and taken on trips when it is desired to “keep an ear” on amateur radio or other high frequency activity. The receiver utilizes rear panel plug-in coil assemblies which contain the RF amplifier, mixer, and oscillator tuned circuits. Each plug-in coil assembly also comes with a separate dial scale, which is inserted onto the front panel for displaying the tuned frequency. A very smooth 6 to 1 planetary drive is used for tuning the receiver. Other front panel controls include RF preamplifier peak, volume control, Beat Frequency Oscillator adjustment, and RF gain control. Other switches include filter bandwidth, AM/CW/SSB selection, Power, and a general coverage/band spread control for certain plug-in assemblies. The receiver is intended to drive head-phones via a rear panel jack, but has sufficient output to drive a small external speaker.
