Oscilloscope FNIRSI 2C53T Plus, 3-in-1, with True RMS Multimeter and DDS Signal Generator

The FNIRSI 2C53T Plus is a multifunctional portable measuring instrument combining a dual-channel digital oscilloscope, a 19999-count True RMS multimeter and a DDS function generator in a single unit. The Plus version features an upgraded dual-channel oscilloscope with an analogue bandwidth of up to 50 MHz and a real-time sampling rate of up to 250 MSa/s. Compared with the previous standard version, it additionally provides waveform mathematics, FFT spectrum analysis, cursor measurements, X–Y display and persistence modes, while the multimeter resolution has been increased to 19999 counts. The integrated rechargeable battery and compact enclosure are suitable for electronic equipment diagnostics, repair, adjustment and measurements at the workbench or in the field.
