Yokogawa Electric (www.yokogawa.com) has introduced a four-channel oscilloscope that comes with up to 16-bit logic inputs — the DL7440 Digital Oscilloscope.
Offered in a convenient, benchtop-sized package, the oscilloscope does not only enable users to capture up to 16 logic signals, it also allows for simultaneous measuring of up to four analog signals without synchronizing two independent oscilloscopes.
Most oscilloscopes featuring high sampling rates may not accurately capture waveforms if their memory size can not adequately sustain the monitoring period. DL7440’s large record memory effectively increases monitoring time while allowing users to keep a high sampling rate, and ensure an accurate waveform monitoring. Its zoom in feature can be utilized to observe images on one or two segments of the captured waveform.
Designed with a history memory function, the oscilloscope separates large recording memory into a number of segments while automatically saving a maximum of 4,096 captured waveforms. Setting a shorter record length allows users to increase the number of screens saved to history memory.
Meanwhile, the oscilloscope’s history search function allows users to instantly locate waveforms of interest and abnormal waveforms from the history memory’s stored waveform data.
The oscilloscope also permits users to calculate statistical data based on the waveforms’ parameter values. This feature also displays the minimum value, maximum value, standard deviation and the average value of the parameter. Users can verify the parameters of the waveform in the history memory.
