Frequency Response Analyzers
-
Frequency Response Analysis (also referred to as Transfer Function Analysis) measures the output spectrum of a system relative to a stimulus, and is used to characterize the dynamics of the system under test. The technique measures the magnitude and phase relationship between output and input waveforms as a function of frequency. The input signals may be from a wide range of sensors including acoustic (microphones/sonar), mechanical (accelerometers/displacement transducers), optical (photodetectors), and electrical (amplifiers).

Standard Optical Interleaver
-
An innovative technique for expanding the number of channels per fiber involves an optical device, called an optical interleaver. For example, in most DWDM equipment, the standard channel spacing is 100 GHz. But spacing the signal-carrying frequencies every 50 or even 25 GHz can double or even quadruple the number of channels per fiber. This job is accomplished by an optical interleaver. Such a device takes two multiplexed signals with 100-GHz spacing and interleaves them, creating a DWDM signal with channels spaced 50 GHz apart. The process can be repeated, creating even denser composite signals with 25-GHz or 12.5-GHz spacing. The signals at the receiving end are recovered with the same devices used as splitters or optical de-interleavers. Thus, devices and/or networks can be upgraded without requiring that all devices be upgraded, or network bandwidth can be increased.

AC Power Sources, Frequency Converter
MAC-01, -02, -03
-
For reliability, all models of the Titan AC Power Sources/Frequency Converters are fully current limit protected against either continuous or transient short circuit or overload conditions. When an overcurrent condition exists, the internal current control loop overrides the voltage control loop and scales back the sinewave drive until it sees a safe output current level.

Standard Electromagnetic Vibrator
KD-9363-EM
-
King Design Industrial Co., Ltd.
The purpose of vibration testing is to make a series of controllable vibration simulation in lab, no matter generated by natural or man-made vibration environment; such as waves, tidal flaps, wind, earthquake or rain and so on. It is to test if the product is capable of sustaining the vibration environment exerted from transporting or usage along its effective life cycle; and certify the standard of design & functional requirement of product. The value of vibration testing is to confirm the reliability of products and effectively screen out the bad products in factory; avoiding damages occurred at arrival; and to assess the failure analysis on the non-performing products; expecting to reach a high standard, high-reliability products. The vibration test stresses on the continuity and fatigue; and contributes to the understanding of product’s status under vibration circumstance in a normal environment; and avoids the product’s unpredictable damage caused under certain vibrating frequency for a long time.

Radio Frequency Cable Tester
RFCT
-
Textron Systems’ Radio Frequency Cable Tester (RFCT) allows for on-site testing and maintenance for radio frequency (RF) transmission paths within a platform. Using preconfigured databases of sweep parameters and pass/fail criteria, the RFCT quickly determines the status of installed RF cables. The RFCT checks each cable’s performance characteristics to include voltage standing wave ratio (VSWR), insertion loss (IL), phase and phase matching. If a cable fails a test, the RFCT automatically determines the distance-to-fault (DTF). With its intuitive touchscreen-based user interface and lightweight, ruggedized packaging, the RFCT is the gold standard for operational-level RF cable testing.

Primary Standards
-
Primary standards (often also referred to as mechanical dead-weight testers, pressure balances or primary pressure standards) are the most accurate reference instruments for pressure. Their functional principle is based on the physical principle of pressure = force/area. Mass pieces placed on the top of a piston-cylinder system are the source of a precisely defined force. By producing a certain (counter) pressure inside the primary standard an equilibrium is achieved: the mass pieces, including the free-running piston of the piston-cylinder system, are floating, which will lead to a very accurate pressure at the test port which measured through piston gauge technology.

Individual UPC Bar Code Standards
-
The UPC Verification Calibration standards are a unique set of symbols that assures an exact and reliable primary bar code standard exists for UPC codes based on ANSI X3.182/ISO 15416 methodology. These standards assures that manufactures of verification equipment, scanners, QC labs and end users now have an accurate basis for checking the measurement capabilities of their equipment. These standards are intended as a fundamental calibration tool for an QC program, providing a continuous scale from best to worse case characteristics of each parameter. With complete NIST traceable data supplied, it is ideally suited to those requiring traceability, such as ISO certification. Each symbol is individually calibrated to ANSI X3.182/ISO 15416 standards using a custom built microdensitometer. These cards are supplied calibrated for use with a 6 mil scan aperture and 660nm wavelength. (calibration wit other aperture sizes or wavelengths is available)
