This document describes the features and characteristics of the digital oscilloscope, including Go-No Go and auto setup sequence, FFT function, built-in help menu, multi-language and PC software. The digital oscilloscope has a bandwidth of 150MHz, 2 channels, 8-bit vertical resolution, 2mV/div to 5V/div vertical sensitivity, AC, DC, ground input coupling, 1MΩ input impedance, positive and negative polarity, etc.
The Tenma 72-7235 is a 150 MHz bandwidth, 2‑channel digital oscilloscope with a 5.7‑inch colour LCD (320 × 240) and a range of measurement functions such as FFT, autoset, and cursor measurements. It offers a real‑time sample rate of 100 MS/s per channel, an equivalent sample rate of 25 GS/s ET, and a record length of 125 kK per channel.
The instrument includes standard interfaces (USB, RS‑232C, printer port, GPIB) and supports various trigger sources and modes. Power is supplied from 100‑240 V AC (48‑63 Hz auto‑selection), and the unit measures 254 × 142 × 310 mm. Accessories include power cord, manual, and two GTP‑150A probes.
