1 Phase Sensitive Multimeters A new generation of versatile measurement instruments PSM1700 PsimetriQ 10uHz to 1 MHz PSM1735 NumetriQ 10uHz to 35 MHz Versatility without compromise In a world where engineers from many different application areas require ever increasing speed, flexibility and measurement accuracy, N4L introduce a new generation of versatile measurement instruments that offer leading performance in every mode without the compromise on accuracy or the additional cost that is commonly associated with such flexible instruments. Utilising the latest DSP and FPGA technology to optimise 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.

2 Whether you will make use of just one or all six of the primary measurement modes included in the PSM1700 and PSM1735, you can be sure of the exceptional accuracy, speed and ease of use that only the latest design technology can provide.
