Mixed-signal 'scopes

Yokogawa has added the DL9705L, DL9510L and DL9505L to its range - three mixed-signal oscilloscopes that complement the DL9710L.

The DL9000 series MSO models allow simultaneous multi-channel monitoring of devices and electronic circuits that handle both digital and analog signals.

The DL9710L can simultaneously monitor 32 digital and four analog input channels, and features 5 GSa/s and 1 GHz bandwidth, making it suitable for a wide range of applications.

Some users do not need such a large bandwidth or so many logic input channels. The company has enhanced its line-up with these three models, allowing users to choose the most appropriate unit for each application.

With the DL9000 series MSO models, users can simultaneously monitor 16 or 32 digital signal channels as well as four analog signal channels with a bandwidth of either 500 MHz or 1 GHz. This allows increased efficiency during the development and evaluation phases for mixed-signal devices and electronic circuits.

The DL9000 models can accurately capture high-speed signals at the high sampling rate of 5 GSa/s. The captured signals can be saved to history memory and users can redisplay the saved signals without having to make special settings.

This allows users to individually verify captured signals and the relationship between channels if an abnormal signal occurs.

The series varies the display of captured signals according to their occurrence frequency, using a data stream engine that is a company-developed signal processing IC.

With this capability, users can determine the frequency of noise, fluctuations and other abnormalities by viewing the display; high-frequency events are indicated with a thick line and low-frequency events with a thin line.
