NV150 is a compact lightweight single trace microcontroller based 15 MHz oscilloscope that has been specially designed to meet the requirements of schools. The sweep circuit employs the LPS trigger technique developed by us. This technique gives the instrument outstanding trigger performance far beyond the bandwidth of the vertical amplifier. All important supply voltages are stabilized. A principal feature of the NV150 which makes it an indispensable instrument for servicing, is the builtin component tester. This allows both passive and active components to be tested, while still in-circuit and therefore makes servicing more efficient and cost effective. The front panel has been designed for easy operation with all controls clearly identified. NV150 15 MHz oscilloscope is user friendly & an ideal service instrument.
