Defining Signals and Triggers

The data cable is made of high quality, extremely flexible wire and high quality connectors. It is
expensive, so please remember to pull on the connectors; not the wires.
The connectors are designed to mate to .025 square posts and can be side-stacked on 100mil
centers, making them ideal for direct connection to standard square post connectors. Additionally,
they mate firmly with the included micro-grabber hooks for connecting to IC leads.
The DigiView DV1-100 hardware is designed to monitor digital logic signals in the -5 to 10V range,
Model DV3100 is designed for signals in the -20 to 20V range and Model DV3400 is designed for
signals in the -50 to 50V range. Standard overshoots and undershoots common to digital systems
will not harm it. The data lines have extra static protection circuits, current limits and
impulse suppression. However, mishandling could still damage them. Simply treat them like
you (should) treat your valuable one-of-a-kind target and DigiView will give you years of service.
The hardware will ignore any data lines that are not defined as part of a waveform or part of a
trigger. This prevents unused signals from eating up the sample buffer space, even if they are
connected to active signals. Waveforms that are DEFINED but disabled, will be captured but not
displayed.

are likely to monitor lends itself well to our compression technique(s). Compression ratios of 100:1
are common. With sparse data, compression ratios of over 200,000:1 are achievable. Since the
degree of compression depends on the amount of activity, you will achieve maximum compression
if you only define signals of interest. DigiView analyzers will always sample at the maximum rate
for the mode selected. Due to automatic real-time compression techniques, you receive the
benefits that down-sampling would achieve (longer captures) without the loss of data resolution.
Current DigiView hardware has either 18 or 36 physical channels. However, we like to think in
terms of symbolic names representing individual signals (clock,ALE) or groups of signals
(DataBus, Address) rather than channel numbers(0,1,2..). We start by defining SIGNALS in
