Compact digital oscilloscopes offer enhanced waveform display and analysis

15 June 2005 Test & Measurement

The new SignalXplorer DL9000 range of digital oscilloscopes from Yokogawa combine high-performance waveform display and analysis functions with what the company claims is the most compact and lightweight design ever seen in its class.

Featuring a frequency bandwidth of 1,5 GHz, sampling rates of up to 10 GSps and, with memory lengths of up to 6,25 MW, these four-channel instruments offer an enhanced waveform accumulation function that allows up to 450-million digitised points to be acquired and displayed every second.

The DL9000 Series measures 350 x 200 x 178 mm and has a mass of only 6,5 kg. Despite its sleek and narrow profile, the instrument is still able to incorporate a 213 mm LCD screen.

The instrument's signal-processing section generates display data from the analog to digital converted data, and processes the waveform and parameter calculations. This function is based on an ADSE (advanced data stream engine) CMOS IC that has a high level of integration, allowing data memory to be incorporated on the same chip. The signal-processing section is based on proprietary architecture specifically designed to offer very high speed waveform display updating.

The new waveform accumulation function, which is additional to conventional waveform accumulation, allows an image, identical to overwritten history waveforms, to be dynamically and continuously generated in parallel with waveform acquisition.
