Source Measure Units
NGU
Source Measure Unit
Thanks to their extremely high accuracy and fast load recovery time, the R&S®NGU source measure units (SMU) are perfect for challenging applications. A special ammeter design is used to precisely measure current drains from nA to A in one pass – no need to make multiple measurement sweeps. The instruments’ short recovery times enable them to handle fast load changes that occur, for example, when mobile communications devices switch from sleep mode to transmit mode. With high speed data acquisition, every detail is detected down to 2 μs resolution.

Noise Receiver Modules And Noise Switching Modules
MT7553 Series
-
Noise Parameters are the non-50Ω extensions of Noise Figure, and are an important modeling and model validation tool to understand how a device-undertest’s performance changes as a function of source impedance. Noise Parameter measurements are typically performedusing a Vector Network Analyzer (VNA) to measure the S-Parameters of the DUT, and a Noise Analyzer (either Noise Figure Analyzer NFA or Spectrum Analyzer SA) to measure the noise power of the DUT. Noise parameters are calculated from a combination of knownsource impedances, S-parameters and noise powers.

Response Dynamics Vibration Engineering, Inc.
Effective vibration isolation is critical to the performance of many systems. It is often much more challenging than expected because the structural dynamics of the supporting structure, and the isolated structure, also affect the isolation performance. Isolation resonances can often create other vibration problems and confound an engineering team. We have successfully designed vibration isolation into countless systems over the years using unique custom solutions as well as adapting standard components and applying them properly to the design.
