EMX-4250 VTI Instruments "Smart" High Density Dynamic Signal Analyzer

The Ametek / VTI Instruments EMX-4250/4251 Series "Smart" High Density Dynamic Signal Analyzers incorporate best-in-class analog design methodology to deliver industry leading measurement accuracy. These instruments are ideal for a wide range of applications including noise vibration, and harshness (NVH), machine condition monitoring, rotational analysis, acoustic test, modal test, as well as general purpose high speed digitization and signal analysis.

204.8 k samples / second /channel data rates extend the operational capabilities of DSA analyzers to new levels by ensuring sampling and bandwidth performance is capable of accurately capturing all critical frequency domain information, while delivering the flexibility needed for general purpose applications.

Aggressive anti-aliasing filter performance (user selectable / definable analog and digital filter combinations) eliminates power spectrum of unwanted signals that contribute to measurement errors delivering confidence.

Differential inputs deliver superior common mode performance far beyond levels capable with other implementation approaches. While the latest 24-bit ADC technology delivers exceptional signal resolution, especially when combined with multiple input ranges.

Wide -105 dB spurious free dynamic range (SFDR), a key measure of the superior measurement fidelity provided by this instrument, ensures that the strength ratio of the fundamental signal of interest signal is exceptional.

"Intelligent" Signal Conditioning delivers exceptional measurement flexibility with multiple options to support a wide range of transducers and signal types including IEPE and charge transducers.

Cross channel phase matching <0.01° delivers the uncompromised phase response required for accurate single and cross channel measurements common in most DSA applications.

Auto-ranging +/-100 mV to +/-10 V inputs maximize signal resolution by automatically selecting the correct input range for the signal. Software selectable, this function can be used during setup and configuration to identify the most appropriate gain level.
