Frequency Response Analyzer 10 µHz - 50 MHz, 2/3 Channel | PSM3750 series

PSM3750 Frequency Response Analyzer / Precision Frequency Response Instrument for Testing & Measurement

Highest Measurement Accuracy – compactly integrated
As a frequency analyzer and response measurement device, the PSM3750 delivers reproducible data for frequency analysis and evaluation – from the lab to quality assurance. At the same time, it demonstrates its strengths as a powerful Frequency Response Analyzer in gain/phase measurements across broad frequency ranges.

Technical Power in a Compact Package
Precise sweep techniques, high signal purity, and clear displays ensure low uncertainty and excellent repeatability. Calibration and measurement remain transparent; software and reporting tools deliver centralised information. When required, the instrument also serves as an auxiliary frequency meter, accurately displaying frequencies and documenting them directly.

User-Friendly Operation and Modern Interfaces
USB, LAN, RS-232, and GPIB seamlessly integrate the device into automated test systems. The “PSMComm2” software accelerates setup, display, and reporting – measure, compare, and document in one continuous workflow. Compatible with existing equipment racks and lab infrastructure.

Your Advantage: Precision and Future-Proof Design
With the PSM3750, users gain an instrument that saves time, delivers dependable results, and integrates flexibly into a wide range of applications. It combines precision, versatility, and ease of use in a single device and meets the high demands of modern electronics engineering.
