Maintaining the proprietary low inductance design of all N4L precision shunts, the HF200 and HF500 offer a precision measurement solution to a wider range of power applications.

For power applications such as high frequency drives or low power lighting ballasts that may be influenced by the capacitance of typical voltage measurement devices, the Ultra Low Capacitance Probe is designed to present exceptionaly low capacitance to ground.

Used in conjunction with the PSM1735 Phase Sensitive Multimeter, the TTF35 provides a simple, fast and accurate measurement solution to ADSL and VDSL telecom filter attenuation testing.

With a 19″ width chasis and modified rear panel design, the PPA2600 offers convenient rack mounting and the option for 50Arms direct current inputs.

While maintaining the flexibility and convenience of 1 to 3 phase ‘base’ instruments, Master Slave mode provides fully synchronised analysis for power applications with up to 6 phases with the PPA2500 Series Precision Power Analyzers

With models from 100mA to 5000A and either AC responding or AC + DC designs, the N4L current transformer range includes a current sensing solution when in-line shunt connection is not possible.

N4L moves into a larger facility to support the rapidly growing PPA power analyzer range and continued success of the PSM frequency response analysis products.

Simplifying the test of maximum inrush current for single phase devices up to 10Arms, the Phase Controlled Inrush Switch is combined with any PPA range power analyzer gives precise phase controlled switch-on up to 300Apk

Maintaining our philosophy of continual product development, an upgraded version of PSMcomm is launched that incorporates recently enhanced functions in the PSM17xx series frequency response analyzers.

Extending our range of laboratory power amplifiers, the LPA05 A or B provide x10 gain with outputs of up to 40Vpk or 8Apk from DC to 1MHz

Power analyzer accuracy certification: Unique to N4L, all Power Analyzers are supplied as standard with certification of measurement accuracy over the complete operating range of DC to 2MHz.

Combining years of experience in high frequency measurement techniques with innovative developments in analogue and digital design, N4L introduce the very latest in power analysis instrumentation.

Using front panel emulation of the PSM1700 series, PSMcomm provides PC control, presentation and data storage of all PSM functions plus a ’sequence’ mode to simplify tests against a series of user defined test limits.

Strategically located in the Midwest U.S. heartland in Chicago’s suburban high-tech corridor, Newtons4th North America provides sales, support, calibration and service facilities for the N4L product line in North America, South America and Canada.

When using our PSM range in LCR mode, compensation of the parasitic impedances found in connection cables has always been offered for specified single frequencies. Now, a versatile sweep compensation mode permits open and short circuit compensation over any selected frequency range with a user selectable number of steps and storage of the compensation values into non-volatile memory for recall at any time.

Complementing our range of passive injection transformers, the LFIM uses an active opto-isolated design to permit isolated signal injection in control loop testing applications from DC to 100kHz.

 Injection transformer range

Incorporating a high performance toroidal ferrite and high voltage isolation design (600V Cat II), the HV injection transformer provides isolation of a PSM signal generator in control loop analysis applications and will operate over a frequency range of 5Hz to 15MHz.

Designed for use with the PSM1700 and PSM1735 units, the IAI provides increased impedance analysis accuracy and extends the frequency range of LCR measurements 35MHz.

Utilising an innovative design unique to N4L, the HF series shunts provide a high precision current sensing solution for power measurement applications from DC to 1MHz.

Increasing our range of PC software options, CommGRAPH offers versatile computer control of FRA, PAV and LCR measurement functions on any PSM unit. The software provides data presentation in tables or graphs and allows data to be stored in .txt format or exported directly into written documents or spread sheets.

Covering an exceptional frequency range of over 12½ decades (10µHz to 35MHz) PSM1735 NumetriQ uses direct digital analysis and heterodyning techniques to achieve outstanding accuracy (eg. high frequency phase accuracy of 0.1° + 0.0001°/kHz) at a fraction of the price of other high frequency instruments. PSM1735 NumetriQ uses the same proven, easy to use controls and display as the PSM1700 PsimetriQ, and has the same versatile set of functions: FRA, PAV, LCR, power harmonics and true RMS. The inputs are balanced, ground referenced, differential inputs suitable for direct connection or for use with oscilloscope probes to minimise circuit loading. The versatile high accuracy measurements at high and low frequencies at low cost makes the PSM1735 NumetriQ suitable for production testing and education as well as research and development applications.

PSM1735 Phase sensitive multimeter (NumetriQ)

PsimetriQ PSM1700 now has the capability to record up to 8000 measurements at a user defined interval from 10ms to 1 hour. Up to 4 results may be stored per record, and either saved to RAM or directly into non-volatile memory. Each function may then be viewed as a table or as a graph against time. As with all functions of N4L instruments, the data may be retrieved to a PC for further analysis.
