PXI Triple SPDT RF Switch MCX 75 Ohm
40-830-103
The 40-830 is a 75 RF Switch available with 3 or 6 separate SPDT relays in a single PXI slot. Both versions have been designed to exhibit low insertion loss and VSWR through the use of modern RF relay technology at an affordable cost. The switch banks have been carefully designed to ensure excellent and repeatable RF characteristics to frequencies of 3GHz with each path having a nominally equal insertion loss. The design of the 40-830 minimizes the injection of noise and unwanted signals into the signal path by careful attention to the mechanical and electrical design.

Amplifiers
Motion Control Systems'' linear amplifiers are high performance servo controllers that produce very smooth sinusoidal motor currents using a linear amplifier output stage. In combination with a sinusoidally wound MCS brushless motor, the linear amplifier can achieve extremely precise rotational control with less than 1% torque ripple, no acoustic noise and almost undetectable levels of electromagnetic interference. Standard programmable features allow greater design flexibility, easy installation and start-up.

Optical Channel Monitor
Optoplex Optical channel monitor (OCM) uses proprietary thin-film interference filter technology combined with a micro-actuator and high-speed electronics. Optical channel monitor is used to measure critical information data on optical transmission signals in DWDM networks for monitoring signal dynamics, determining system functionality, identifying performance change, and providing feedback for controling network elements so as to optimize operational performance. In particular, Optoplex Optical channel monitor can automatically scan the C-, L- or C+L-band wavelength range and precisely measure channel wavelength, power, and optical signal-to-noise ratio (OSNR). See the following schematic diagram for OCM working principle.

Low Voltage DC / Battery Powered HV Amplifiers
WMA-01 And WMA-01LF
The Falco Systems WMA-01 is a high voltage amplifier that runs from an 24 - 30V DC power supply and can be battery powered if required, e.g. for use in a Faraday cage. Its internal high voltage generator is inductor-free and hence does not spread magnetic interference in sensitive experimental setups. The output noise is impressively low at 3mVrms. For extremely low noise applications where bandwidth is not an issue, a dedicated WMA-01LF version is available that contains an output low pass filter capacitor which reduces the bandwidth to 50Hz, but makes the noise drop to below 0.1mVrms. This bandwidth-limited amplifier is ideal for MEMS or piezo positioning with manual voltage adjustment.

VHF/UHF Handheld Signal Location Antennas
Type NVF-2
The Type NVF-2 series of handheld directional antennas are used to locate interfering signals or noise in either the 420 – 470 MHz (Type NVF-2A) or the 900 MHz ISM band or cellular telephone bands (Type NVF-2B). Both models incorporate a solid reflector positioned behind a resonated half wave driven element, both elements being mounted on a fiberglass rod with an integral pistol grip. The configuration of the reflector and driven element are such that a deep null in the signal being received will occur when the antenna is pointed in the direction of the signal being radiated. A T-pad resistive attenuator is also incorporated in the antenna mounting enclosure to aid in the direction finding process on very strong signals or when excessive reflections present multiple returns.
