GHz digital scope

Yokogawa Australia has released the DL9000 compact digital oscilloscope, capable of a maximum sampling rate of 10 gigasamples per second at bandwidths of 1-1.5 GHz.

It is the company's first GHz-bandwidth digital oscilloscope.

The unit features an advanced data stream engine (ADSE), a waveform data processor that enables the accurate acquisition of high-speed, GHz bandwidth signals for screen display.

In the fastest waveform acquisition mode, up to 1600 partitions can be created in acquisition memory, dead time can be reduced to 400 ns and a maximum of 2.5 million waveforms a second can be acquired by each of four channels.

In accumulation mode, the acquisition rate is 25,000 waveforms a second per channel. Of those 25,000 waveforms, the last 2000 can be recorded in history memory.

When an abnormal signal occurs, these features enable the verification of acquired data for individual waveforms, the display and examination of the correlations between data from channels, and the measurement of waveform parameters.

The instrument is fitted with a 213 mm colour LCD (XGA: 1024 x 768 pixels) and acquired signal waveforms can be accumulated and displayed by intensity level according to the frequency of abnormal phenomena. This screen display also gives an indication of frequency and S/N ratio of noise and fluctuations.

It also features a 2.5 GHz bandwidth active probe for accurately probing high-speed signals.
