Three new models have been added to the Yokogawa DL9000 Series of mixed-signal oscilloscopes (MSOs).
The DL9705L is a 32-channel instrument with a bandwidth of 500 MHz and a sampling rate of 5 GSps; the DL9510L has 16 channels, a bandwidth of 1 GHz and a sampling rate of 5 GSps; and the DL9505L has 16 channels, a bandwidth of 500 MHz and a sampling rate of 5 GSps.
The DL9000 Series MSO models allow for simultaneous multichannel monitoring of devices and electronic circuits that handle both digital and analog signals. Unlike existing MSOs which offer limited display and analysis capabilities for logic signals, this family is optimised for users who wish to analyse logic signals as well as analog waveforms. The instruments feature the full state display and bus display functions typically found on logic analysers, allowing co-ordinated analysis of analogue and logic signals.
Other features include high-speed acquisition and quick response, with an uncompromised update rate of up to 25 000 waveforms per second, a history memory function for more efficient waveform observation and analysis, and powerful zoom and search functions.
The history memory function allows the user to recall and display previously acquired data from up to 2000 screens' worth of past waveforms. This ability to redisplay and subsequently analyse data offers significant benefits in troubleshooting and analysis.
The MSOs also include powerful functions for searching the memory for desired waveforms, and zoom functions for observing these waveforms in detail. In addition to searching based on criteria such as signal edge, pulse, and multichannel state, the history memory can be searched by serial or parallel waveform patterns and waveform parameters. Users can quickly find desired waveform data in memory, enlarge the area with the zoom function, and scroll the data.
A dual-window zoom function simultaneously zooms in on two areas. Two individual zoom factors and positions can be set with independent timescales and displayed simultaneously. Using the automatic scroll function, it is possible to automatically scroll waveforms captured in long memory and change the position of the zoom areas. Powerful trigger functions include the ability to trigger conditions using a logic signal as the source. Various trigger conditions can be combined to capture only the desired signals.
Options are available to allow serial bus analysis to be carried out on I²C, SPI, CAN and LIN bus systems, with triggers for these bus types included as standard features. These functions make it easy to discriminate between partial software failures and physical-layer waveform problems when troubleshooting systems by observing the physical-layer characteristics of signals. With the dual-window zoom function, the instruments can simultaneously analyse and display waveforms from buses running at different speeds.
