Coaxial Receiver Protector
Where size, weight and power handling are the principle constraints, a TLM air-spaced coaxial limiter range provides an excellent compromise between waveguide and microstrip limiters. These devices are able to withstand higher power levels than microstrip solutions but still retaining a relatively compact package, Teledyne’s designs offer a low insertion loss and incorporate the same wide range of features as our waveguide limiters. Suitable for continuous operation at peak power levels of several kW's and mean power levels of 100's watts with sub- microsecond recovery time - over 10% bandwidth in <100mm length (at S-Band).

Thermitest
THW-L2
Designed with speed and operational simplicity in mind, the Transient Hot Wire (THW-L2) Liquid Thermal Conductivity Meter is an advanced measurement system for direct determination of the thermal conductivity of liquids and pastes in accordance with ASTM D7896-19. In less than 2 seconds, a single measurement of small volumes of liquids and pastes can be accurately and precisely measured for thermal conductivity. Using a non-stationary measurement approach, the THW-L2 uses rapid test times to limit convective effects for samples with a wide range of viscosities. The THW sensor consists of a 60 mm heating wire that is fully inserted into an isothermal sample. A constant current source (q) is used to heat the sensor wire and the temperature rise is recorded by monitoring the change in electrical resistance of the wire. The slope (m) is determined from the plot of temperature rise vs. logarithm of time and is used in the calculation of thermal conductivity (λ). Liquid samples of high thermal conductivity will have a lower slope, while liquid samples with low thermal conductivity will have a higher slope.

Energy Dispersive X-ray Fluorescence Spectrometer
Pharmaceutical Elemental Impurities Analysis System
Control of Elemental Impurities in Pharmaceuticals In the pharmaceutical industry, the analysis of elemental impurities is necessary to ensure the safety of pharmaceuticals. In December 2014, the "Guideline for Elemental Impurities" (Q3D) was issued by the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH), consisting of representatives from Europe, the U.S. and Japan. In Japan, the "Guideline for Elemental Impurities in Drug Products" (PFSB/ELD Notification 0930 #4 from the Ministry of Health, Labour and Welfare) was issued, and will be applied to new drug products submitted for approval after April 1 2017. For 24 elements categorized in Class 1 to Class 3, residual quantities in pharmaceutical drug products must be controlled within permissible limits. Although ICP-AES and ICP-MS are used for precise analysis of elemental impurities, X-ray fluorescence spectrometers can be used as an alternative analysis method. This is because they can quantitatively and qualitatively analyze a variety of elements nondestructively, and without chemical pretreatment, unlike ICP-AES and ICP-MS systems. The X-ray fluorescence spectrometry has been adopted as a general method of analysis in the U.S Pharmacopeia and the European Pharmacopoeia. (USP<735>, Ph.Eur.2.2.37)

Near Field Probes
A typical emi emission test is performed using broadband EMC antennas such as biconical, log periodics, Combilogs and horns. These antennas usually placed at 1, 3 or 10 meter distance as required by the test specification. These is considered far field measurements and the emission limits are given for the specific distance by the specification. During EMI compliance measurements, the emissions levels from products are compared with these limits. If the product exceeds these limits it is considered failing. These tests are typically conducted in a open area test site IOATS) or inside an anechoic chamber.

Reduced Voltage Motor Starting Panels by Reactors
A method to limit motor starting current is a series reactor. Iron core or air core reactors can be used for starting purposes. If an air core is used for the series reactor then a very efficient and reliable soft starter can be designed which is more suitable for high MW ratings of synchronous/induction motors at MV levels. The reactors are designed with taps.

Transmitter (Export Only)
SMB
The input section features the unique servo bias input circuitry with a standard TA5M type jack for use with electret lavaliere mics, dynamic mics, or line level signals. A DSP-controlled analog audio limiter is employed before the A-D converter. The limiter has a range of more than 30 dB for excellent overload protection and a dual release envelope that makes the limiter acoustically transparent while maintaining low distortion. The limiter recovers quickly from brief transients, with no audible side effects, and also recovers slowly from sustained high levels to keep audio distortion low while preserving short term dynamics.

Memory Analyzers
Market drivers in the memory sector have changed. Gone are the days of simply pushing Moore’s Law to ever faster data rates. The memory designs of today and tomorrow must also be smarter than ever before. Today, handheld and wearable computers must draw from a limited battery reserve while serving up fast, responsive, and compelling mobile experiences. Meanwhile the cloud of data centers and server farms that feed us these compelling experiences must continuously grow while simultaneously reducing overhead and environmental impact. These two different markets have the same goals: smarter memory, smarter control systems, and lower power usage.
