Mixed-signal oscilloscopes boast 2.5Gs/s sample rate

Agilent has announced the 16-model InfiniiVision 4000 X-Series of digital storage oscilloscopes (DSOs) and mixed-signal oscilloscopes (MSOs) that according to the company are fully upgradeable. The portfolio includes two- and four analogue-channel units having bandwidths of 200MHz to 1.5GHz.

DSOs and MSOs

With all analogue channels active, the maximum real-time sampling rate is 2.5Gs/s. In the interleaved mode, in which only half of the channels are active, the maximum rate is 5Gs/s and memory depth is 4M points. A standard feature is the ability to segment memory to capture in one acquisition multiple iterations of short-duration signals. These scopes also incorporate the manufacturer's proprietary MegaZoom IV technology, with which the instruments can capture 1 million waveforms/s, a key to finding anomalous signals that occur only infrequently. To avoid aliasing (display of non-existent components in signals that contain frequencies above half the sampling rate), most users will prefer to use the interleaved mode for viewing signals that have significant content above 1.25GHz, stated the company.

Among many other features is an 800 x 600 pixel 12.1in. capacitive touch screen that supports gestures, such as dragging panels to desired locations on the screen. The MSOs perform five functions: scope, logic analyser, protocol analyser, optional dual-channel 20MHz waveform generator with arbitrary-waveform-generation capabilities and optional three-digit digital voltmeter. All of the scopes incorporate a zone-touch trigger facility that lets you use the touch screen to define rectangular zones that contain waveform features on which you want the scope to trigger.

The MSOs add 16 digital channels, each with a maximum sample rate of 1.25Gs/ and a memory depth of 2M samples. Prices range from $5600 to $22,000.
