Tektronix has created a technique for showing up rogue waveforms on an oscilloscope to identify intermittent faults more quickly.
The company has put the scheme, called Wave Alert, into a new family of midrange oscilloscopes. It uses the processors that update the screen to work out if a waveform is out of place or whether it is in line with previous waves.
Trevor Smith, product manager for Tektronix, said: "It uses the persistence mode of the scope. It figures out what is the norm and what is anomalous."
The scheme's sensitivity depends partly on the decay time of the scope's screen and partly on a sensitivity setting, which determines how much deviation the scope accepts before triggering an alert.
The alert may consist of simply colouring the rogue waveform differently, or it may involve dumping the data to disk or popping up a window onscreen.
Compared with previous models in the TDS3000 family, the company has upgraded the waveform update rate from 1800/s to 2400/s.
A software upgrade for both the new scopes and previous models with an ethernet connection lets users with a Web browser access the instrument remotely and control it.
