Low Noise Converter for Radio Amateurs
-
The concept of software defined radios (SDR's) is becoming increasing popular in both commercial, military and Amateur Radio circles. In their basic form, the use simple front end filtering followed by a Quadrature Sampling Detector (QSD) with the post detection processing done in software using the sound card found in PC's. Several popular kits have been developed to introduce Amateurs to the concept.

Environmental Testing
-
Environmental testing and accelerated ageing are testing that may be mandated for certain regions or required standards. But for many products, this testing is not mandated, but if any claim to performance is made then testing should be done to have evidence. In addition, it can help ensure less product returns to defective products that may after sold become faulty due to external environmental impacts.

High Frequency Noise Simulator
SKS-H04GA
-
Shanghai Sanki Electronic Industries Co., Ltd.
The high-frequency noise simulation generator is an EMC test instrument that reproduces high-frequency noise with a fast rise time when the switch is turned on/off. Since the pulse rise time is less than 1ns and contains wide bandwidth noise, it is very suitable for reproducing malfunctions. The line noise entering the power line and the induced noise entering the communication line can be reproduced, and the performance evaluation of the malfunction and function degradation of electronic products can be performed.

Low Noise Amplifiers
-
Our range of ITAR Free, Low Noise Amplifiers (LNAs) cover a variety of applications but are primarily suited to airborne, maritime and ground based radar systems. LNAs are primarily intended to minimise added noise whilst providing high gain so design focusses on the parameters associated with the noise response of the amplifier. They are usually the first amplifier in the Radar detection chain and will have the lowest noise figure.

Environmental (Radiation) Monitoring System
Hawk® EMS
-
The Hawk® EMS is a wall or tripod-mounted radiation monitoring and alarm system designed for use with the Hawk® Radius dual sensor radiation probe. Each EMS System comes with a Hawk Radius Probe. The system is extremely energy efficient and can run for weeks on an internal 9 volt back-up battery if power fails. It is well suited for operating on a small solar panel, which is an optional accessory. The Hawk® EMS features two displays that show the radiation levels measured by each of the probe’s two detectors: the weatherized “pancake-style” Geiger-Mueller tube — which measures alpha (if configured for it), beta, low energy gamma, and x-radiation — and the energy-compensated gamma tube which measures penetrating gamma dose rate. The probe can be mounted next to the EMS system or outdoors, or in adjacent rooms on cables up to 100 ft in length. Standard cable is 3 meters in length. Optional signal booster can support cable lengths longer than 100 feet. Optionally the system can also be configured to share data on ethernet or wireless networks.

Low Noise Prepolarized Microphone
378A04
-
The 378A04 is a matched system that is comprised of a high sensitivity microphone and a low noise preamplifier that contains a built-in filter that enables the free-field response to remain flat over a wide frequency range. The system requires a minimum of 4 mA and measures to 6.5 dBA (5.5 dBA typical) within a cost efficient, prepolarized (0V) design. PCB's model 378A04, the industry's first prepolarized low noise microphone and preamplifier system allows you to measure extremely low amplitudes. In the past this was only possible with externally polarized solutions. With a typical noise floor of 5.5dBA, this microphone system delivers all of the benefits commonly associated with prepolarized systems.
