LV Iron Core Line & Load Reactors
-
Line and load reactors are generally serial-connected to the input and/or output terminals of three phase equipment such as motor speed controllers, inverters and UPS systems. These equipment make use of semiconductor switches such as IGBTs, thyristors, and diodes and therefore create harmonic distortion and high switching over-voltages (dv/dt). Use of such equipment has been becoming more widespread as the technology advances. However, the negative effects of these equipment should not be overlooked.

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.

Single Channel Signal Buffer Module
-
Alliance Support Partners, Inc.
Signal quality problems caused by mismatched impedance can result in intermittent measurements and faulty diagnostics. This is most often observed when transporting a test program from one system to another, such as re-hosting it from an older generation system to a new one. The primary root cause of the impedance mismatch is the signal path from the UUT to the measurement instrument. The switching system technology often is responsible for much of the distortion. The Signal Buffer Module (SBM) is designed to receive a signal from the UUT with high impedance output and accurately reproduced it at the output for delivery to the measurement instrument. The SBM output matches the 50 ohm input impedance of most measurement instruments and result in significantly reduced signal distortion.
