Small-footprint scopes debug buses

The Tektronix DPO3000 lunchbox-sized, two- and four-channel 100-, 300-, and 500-MHz-bandwidth oscilloscopes provide more than three times the screen area and 500 times the waveform-memory depth of the company’s TDS3000 series. The DPO3000s incorporate Tek’s Wave Inspector technology, which facilitates searching through long waveform records for anomalous events. In addition, the new units trigger from, and decode the activity on, five embedded-system buses: serial peripheral interface (SPI), inter-IC (I2C), RS-232, controller area network (CAN), and local interconnect network (LIN).
The DPO3000s incorporate 800x480-pixel wide-screen video-graphics adapter displays, which measure 9-in. diagonally. All models can capture 2.5 Gsamples/s/channel, and all provide a memory depth of 5 Msamples/channel. The screen-update rate is 50,000 waveforms/s. The units feature an Ethernet port and two USB ports—one for memory devices and one for connection to a PC. For bus debugging, the display switches to a text-only mode.
Price range: two-channel 100-MHz unit—$4450; four-channel 500-MHz unit—$10,900. (Prices include National Instruments’ LabView SignalExpress, base version, which you can upgrade to the complete Tek Edition for $699.)
