Spectrum Analysis
S95090B
The S95090B spectrum analyzer (SA) measurement software adds high-performance microwave spectrum analysis to PXI VNAs. With fast stepped-FFT sweeps resulting from optimized data processing, the SA software application provides quick spurious searches over broad frequency ranges. The S95090B software uses the PXI network analyzer's test and reference receivers to complete simultaneous spectrum measurements. Multi-channel SA measurements leverage the PXI VNA's internal swept-signal generators for efficient measurements of spurious signals emanating from mixers and frequency converters. The S95090B spectrum analyzer software application employs source-power and receiver-response calibration as well as fixture de-embedding, providing in-fixture and on-wafer spectrum measurements with the highest level of accuracy. Optional external attenuators should be connected with the VNA’s test ports to avoid receiver compression when measuring large signals.

Frequency Response Analyzers
Frequency Response Analysis (also referred to as Transfer Function Analysis) measures the output spectrum of a system relative to a stimulus, and is used to characterize the dynamics of the system under test. The technique measures the magnitude and phase relationship between output and input waveforms as a function of frequency. The input signals may be from a wide range of sensors including acoustic (microphones/sonar), mechanical (accelerometers/displacement transducers), optical (photodetectors), and electrical (amplifiers).

1000W Ferroresonant Power Supply
Series PRR
Kepco's PRR are 1000 Watt rack mounted laboratory systems power supplies that offer the low cost and very high dependability of ferroresonant voltage stabilization.The ferroresonant stabilizing technique provides extraordinary isolation from a wide variety of source noise. It is inherently short-circuit proof and cannot expose delicate loads to overvoltage hazards. Hence no crowbar, fuses, or bounding circuits are needed. Ferroresonant power supplies use no noise-producing switches or oscillators. Voltage setting is independent of delicate control settings or diode references and requires no comparators, references, or limiters. Efficiency is 70-80%.
