About Product

Utilizing the latest DSP and FPGA technology to optimize the use of innovative analogue hardware, many measurements functions can be derived with great precision from the basic elements of true RMS voltage on two measurement channels plus the phase angle between them. It is from this fundamental relationship between independent voltages and their relative phase angle that the model “PSM” was derived and this is also the key to the unique combination of performance versatility and value provided by the PSM range. The N4L PSM3750 Series Frequency Response Analyzers are built to provide a solution for high voltage, high accuracy, isolated gain and phase measurement. When combining with an Impedance Analysis Interface 2 (IAI2), a high accuracy impedance analyzer is formed in which the PSM3750 Series are able to provide impedance analysis up to 50MHz. Additional features include an oscilloscope, power analyzer, harmonic analyzer and vector voltmeter functions.

Product Functions

 Frequency response analysis
–  The PSM3750 Series offer a complete solution for high frequency, high accuracy frequency response measurements. Featuring a unique 10Vrms output, 500Vpk isolated generator and 500Vpk isolated inputs the PSM3750 is an innovative step forward in frequency response measurement. The PSM3750 Series also offer market leading gain and phase accuracy (0.01dB, 0.025deg) for an isolated input frequency response analyzer
 Impedance analysis with IAI2 (Option)
–  When combined with the optional IAI2 Impedance Analysis Interface, the PSM3750 Series provide an accurate solution for LCR measurements, using a true 4-wire Kelvin technique without the need for external shunts. The IAI2 has a bandwidth up to 50MHz, with a wide measurement range this technology builds on years of expertise N4L have gained in the impedance measurement field (See photo section)
 Isolation for high voltage feedback loop analysis
–  The PSM3750 features a 500Vpk isolated generator; this enables the engineer to connect directly to the feedback loop with no need for an injection transformer. This has been made possible through the development of a truly isolated generator card providing DC & 10µHz up to 50MHz injection bandwidth. In most cases there will be no requirement for attenuators due to the presence of 500Vpk isolated inputs, making feedback analysis simple, fast and flexible
 PSMComm2 Software (Option)
–  The optional PSMComm2 enables the user to perform multiple sweeps during development and compare the sweeps on one single plot. PSMComm2 also includes a database function in which the user can store their projects and organize large amounts of data in a manageable, structured format (See photo section)
