DPO4032

The Tektronix DPO4032 is a 350 MHz, 2-channel Digital Phosphor Oscilloscope (DPO) designed for advanced troubleshooting, debugging, and serial bus analysis. Featuring a generous 10.4-inch XGA color display, a compact 5.4-inch footprint, and the Wave Inspector™ navigation system, it excels in analyzing long record lengths of up to 10 Mpoints per channel. With a 2.5 GS/s real-time sample rate on all channels, TekVPI™ probe interface support, and automated triggering/analysis for serial standards like I2C, SPI, and CAN, the DPO4032 delivers robust performance in a portable and lightweight package.
