Two separate functions on the Scaling menu allow you to review digital input channel information. The Analog Plot function toggles the digital input channel display between a bipolar analog plot and a digital individual bit plot. The Digital Plot function displays the digital input channel as a digital sub-channel featuring each individual bit. Both of these functions are normally dimmed on the Scaling menu unless the file being reviewed is a digital file (specified as such prior to acquisition).
A digital input channel displays either a high signal or a low signal. These two functions offer two different ways of displaying the same high or low digital signal information. The Analog Plot function allows you to toggle the display of these high or low signals between an analog plot of a digital channel (with a display similar to the output of a D/A converter) and a digital plot that shows the state per bit. The Digital Plot function allows you to display the high or low state per bit (0 to 7), with a display option for normally open or normally closed conditions.
