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 phrase “Phase Sensitive Multimeter” was derived and this is also the key to the unique combination of performance versatility and value provided by the PSM range. The N4L PSM1735 Phase Sensitive Multimeter is a comprehensive DFT and true RMS analysis instrument for R&D and production test applications. Specifically aimed at a range of high performance gain/phase analysis applications, amongst which include switched mode power supply feedback loop stability analysis and general frequency response analysis of filters. It has a clear, bright graphics display showing real time values or graphs or tables. It can be operated completely by remote control over RS232 or LAN as an option. PSM1735 provides not only just conventional frequency response measurements but can also be combined with an Impedance Analysis Interface (IAI) or a LCR Active Head to form a high accuracy 35MHz Impedance Analyzer/LCR Meter. It is designed to give optimum performance, speed of measurement and convenience, providing sophisticated measurement capability which is truly market leading performance.

Product Functions
Frequency Response Analyzer (FRA)
– Incorporating a digital signal generator, two differential auto-ranging voltmeters, auto-scale frequency plots and intuitive setup stored into non-volatile memory; the PSM1735 brings accurate and simple to operate frequency response analysis within the grasp of many who could not previously consider an FRA. FRA result can be shown in the front panel display too (See photo section)
Vector Voltmeter
– Unique to the VVM mode is a null meter display that provides the feel of traditional analogue instruments while maintaining the precision of a 6 digit phase display and 1milli-degree phase resolution. A high stability signal generator with direct digital synthesis, true RMS sensing voltmeters and the Discrete Fourier analysis combine to provide phase measurement accuracy beyond any comparable product (See photo section)
LCR Meter
– Whether using an external shunt, a LCR Active Head (10µHz to 5MHz) or the Impedance Analyzer Interface (10µHz to 35MHz), the LCR mode provides all impedance parameters quickly and accurately either at single frequencies or over a user defined frequency sweep. LCR result can be shown in the front panel display too (See photo section)
RMS Voltmeter
– In addition to providing the raw data from which all other functions are derived, each channel can be used directly for applications requiring precision RMS measurement. Unlike many voltmeters, AC and DC components are quantified separately and dBm, peak, CF and surge values are displayed. Both units utilize independent differential circuits permitting simultaneous analysis of two points at a different potential. For example, the input and output on voltage converter or two windings on a transformer
Harmonic Analyzer
– The Harmonic Analyzer mode simultaneously measures individual harmonic components and total harmonic distortion values on both measurement channels. Discrete Fourier Transform algorithms permit fundamental harmonic components to be quantified accurately even in the presence of noise and distortion (See photo section)
Power Meter
– The combination of true RMS measurement channels, precision phase analysis, high speed computation and a versatile graphic display provide an ideal solution to many applications that involve rapid changes in power. Power result can be shown in the front panel display too (See photo section)
PC control, data Capture and file Storage
– The optional PSMComm2 software provides control of all primary PSM functions with graphical or tabular data presentation, dual cursor measurements, an automatic gain phase margin function plus print, copy, save to file and firmware download. The CommVIEW PC software is supplied as standard, provides script file instrument control, result storage in .txt format and firmware download (See photo section)
