RA062-F2 -
Teledyne Defence & Space
The RA062-F2 is a multiple LO module used to generate three pairs of LO signals, each pair being phase matched in order to provide the capability to drive two phase and amplitude matched, high sensitivity narrowband receivers such as might be required for an EW receiver system with DF functionality.The Stepped Frequency Synthesiser is based upon Direct Frequency Synthesis, DFS, whereby the 1GHz input reference signal is multiplied, filtered and mixed to generate a given number of isolated and filtered single tone CW signals from the 1GHz comb. A finely tuned signal is then generated using a multi-way switch to select between the 1GHz spaced CW tones and mixed with fine resolution signals generated using a custom DDS/VCO PLL network. In this way finely tuned signals can be generated between 7.5GHz and 23GHz.

Techimp HQ S.r.L
New IEC standards, IEC 60034-18-41 and IEC 60034-18-42, have been issued to define the procedures for testing partial discharge inception voltage and the long-term performance (endurance) of Type I and Type II insulation systems used in rotating machines fed from voltage converters. Voltage impulse generators are required at least to test turn insulation, but they would be recommended for any testing under power electronics supply because of their capability to simulate the real electrical stress conditions. More generally, any type of electrical insulation system when subject to impulsive voltage waveform during life should be carefully evaluated in terms of partial discharge and endurance behaviour. This is why voltage impulse generators able to provide impulses with controlled amplitude and frequency are needed to face this new testing challenge.

Fairview Microwave Inc.
The new MMIC IQ mixers from Fairview (also known as IQ modulators) utilize a highly reliable GaAs MESFET semiconductor process which integrates a pair of matched double balanced mixer cells, a 90-degree hybrid and a 0-degree splitter/combiner that produces exceptional amplitude and phase balance performance. This level of integration offers size and performance advantages in comparison to discrete module assemblies. With the addition of an external 90-degree IF hybrid module, these IQ mixers can be used as either a Single Sideband Up-converter Mixer or an Image Reject Down-converter Mixer. The benefit of image rejection and sideband suppression can reduce overall system cost and complexity by removing the need for pre-selection filtering. Typical applications include point-to-point and point-to-multipoint radio, VSAT, military radar, electronic warfare, satellite communications, test equipment, and sensors.

This test verifies that power is properly applied, verifies that there are no internal bit errors, and performs other tests to ensure that the bit synchronizer is fully operational with status indication of results. Command-test BIT performs the same functions and can be initiated by the user at any time through the Lumistar software when used on Lumistar PC products. The user has the ability to generate internal pseudo-random patterns and calculate internal bit error rates with or without the injection of forced errors.Various status indicators are also available through the software. The Bit Synchronizer also contains a BER reader as well as frame sync pattern indicator.

VCO Series -
SignalCore, Inc.
The SC5510A and SC5511A are VCO-based, synthesized signal sources with very low phase noise and an amplitude control of 0.01 dB throughout its -30 dBm to +15 dBm output power range. By utilizing a unique multiple phase-locked loop architecture, phase spurs are kept below -70 dBc across the entire tuning range, even at 1 Hz step resolution. Download the data sheet to see how the impressive features and specifications of these modules make them stand out when compared to other small modular synthesizers. These 20 GHz signal sources include an additional, independent RF2 channel with a tunable frequency range from 100 MHz to 3 GHz and a tuning resolution of 25 MHz. The extra channel makes the modules suitable for either single-stage RF conversion systems or dual-stage image suppression up/down converter systems. Both modules make great general-purpose laboratory signal sources where demanding low phase noise and signal purity are required. They are both ideal choices as an integrated clock source for fast DAC and ADC applications, especially those that require variable sampling rates. Full implementation instructions, GUI, driver software, and example code are provided with each module.

TA-100 -
Tech-Aid Products
The TA-100 signal generator was designed to facilitate testing of aircraft fuel flow indicators that require two input signals designated as “Drum” and “Impeller”. This generator provides both signals so as to provide a direct interface to the fuel flow indicator under test. The generator also provides switched power out to the unit under test as well as a 5v source for testing the bezel lighting. The original design was built around the requirements for the AMETEK series indicators (pn: 10171 series). This generator simulates a reference and a time delayed signal of appropriate amplitude for an indication of up to 1200pph for the indicator under test. The “PPH Select” switch provides fixed signal delays representing 0, 200, 400, 800, 1000 and 1200pph flow rates respectively, this provides the mechanic with an expedient check of the indicators accuracy. The “PPH Adjust” control allows the mechanic to vary the signal delay throughout the full range and serves as a good method for checking of pointer smoothness from stop to stop. The unit’s front panel also provides test jacks to monitor the “FDR Output” as well as the drum and impeller signals. The TA-100 requires only 28Vdc to operate. This generator provides a very economical approach to any repair facility or flight department as it becomes an alternative to purchasing two bench top signal generators. The TA-100 generator at the very least can provide a simple functional test and eliminate the high cost of exchanging an indicator as a function of troubleshooting the aircraft system.

Hill Engineering, LLC
Fatigue engineering is subject to uncertainty, and data from well executed tests are used to validate conclusions made by analysis and to provide a basis for structural certification. Our staff have extensive experience in testing materials and components under slowly varying, static loads, and under rapidly varying cyclic loads. Tests under static loads are used to assess material properties or to assess the load-deformation behavior of structural components. Tests under cyclic loads provide time to crack initiation, time to failure, or measurements of crack growth over time. We have extensive experience in measuring fatigue crack growth behavior in metallic materials. Past programs have measured crack growth with microscopy and photogrammetry at the surface, cracked area with direct current potential drop, and through-thickness crack profiles with quantitative fractography. By assessing crack growth with a variety of experimental methods, we enable robust analysis validation for cases of complex cracking. Our capabilities in fatigue engineering allow for careful design of a fatigue test program. Whether the tests use constant amplitude loading or an irregular loading spectrum, we specialize in engineering the test that meet your needs. Much of our experience is in non-standard test programs, which require engineering to optimize the test setup. Few others match our capability and experience in fatigue test engineering.
