Shanghai Jiuzhi Electric Co., Ltd.
Our advanced CDY series Impulse test systems are used for impulse voltage testing of transformers, cables, gas-insulated switchgears (GIS), arresters, and other high-voltage devices. The test systems generate lightning impulse voltage (LI, 1.2/50 µs), chopping lightning impulse voltages (LIC, front time 1.2 µs, front, crest or tail chopped), and switching impulse voltage (SI, 250/2500 µs) in accordance with IEC 60060-1; as well as IEC 60076-3 for transformers, and IEC 62067, 60840 and 60502-1 for cables). By adding extra components, our impulse test system also can generate steeping wave (SWI, >2500kV/ µs) and impulse current (IC, 4/10 µs, 8/20µs, 10/350µs).

Type NVF-2 -
National RF, Inc
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.

COMSOL, Inc.
The design and modeling of microelectromechanical systems (MEMS) is a unique engineering discipline. At small length scales, the design of resonators, gyroscopes, accelerometers, and actuators must consider the effects of several physical phenomena in their operation. Consequently, COMSOL Multiphysics is ideally suited for MEMS applications. To this end, the MEMS Module provides predefined user interfaces with associated modeling tools, referred to as physics interfaces, for a variety of coupled physics, including electromagnetic-structure, thermal-structure, or fluid-structure interactions. You can include a variety of damping phenomena in your model: thin-film gas damping, anisotropic loss-factors for solid and piezo materials, anchor damping, and thermoelastic damping. For elastic vibrations and waves, perfectly matched layers (PMLs) provide state-of-the-art absorption of outgoing elastic energy.

RCT1A and RCT5A -
Powertek LLC
These probes have great bandwidth ensuring accurate measurement even with harmonically distorted wave shapes. For all RCT1A/RCT models, a NIST, NAVLAP, NPL (UKAS) factory traceable calibration certificate and certificate of conformance is supplied. UL/CSA approved materials are used throughout. Three phase and single phase flexible AC current sensors (rope sensors) are available for fast installation in confined spaces, eliminating the need for Electrical Supply Shutdown. Available outputs are 1A @ 2.5VA and 5A @ 0.5VA, this means long cable lengths from current sensor to signal conditioner allow these low VA ratings to be used, even when feeder cable to energy meter distances are large (up to 98 feet / 30 meters)

Pacific Millimeter Products
These waveguide bandwidth detectors use silicon beam lead diodes on a planar stripline circuit to obtain an extremely rugged and compact device. Most millimeter wave broadband detectors have very poor VSWR due to the difficulty in obtaining a good wideband impedance match to the diode. To overcome this problem, these detectors utilize two diodes and an internal matched termination and 3 dB hybrid as shown below. This circuit allows a VSWR of 2.0 or better over a full waveguide bandwidth for most of these detectors. Detectors for waveguides WR-8 and smaller use a single zero bias GaAs diode. The high sensitivity zero bias GaAs diodes can also be special ordered for use at lower frequencies when highest sensitivity is required.

2.7 GHz, 50 Ω, Dual-Terminated SPDT PXI RF Relay Module - The PXI‑2549 is a general-purpose single‑pole double‑throw (SPDT) switch module. You can use it to add flexibility to your switch network or to maintain uniform signal paths across multiple channels when building high‑channel‑count multiplexers. The PXI‑2549 termination resistors minimize reflections on open channels and protect your source or device under test from damage. The module also features excellent insertion loss, voltage standing wave ratio (VSWR), and isolation parameters to minimize signal degradation. You can use its onboard relay count tracking feature to predict relay lifetime and reduce unexpected system downtime.
