Network Analyzer Graphs
Voltage (V)
The graphs displayed by Network Analyzer display voltage level from -5V to 10V on the Y axis
Time (ms)
The time sample runs from 0 to 6.55ms. along the X axis.
Labels
The blue "Y" represents the wire labeled "Y" in a cresnet network.
The red "Z" represents the wire labeled "Z" in a cresnet network.

Network Analyzer Analysis
Network Analyzer offers an analysis of the graphs it displays. A brief note is listed in
the bottton right corner of the graph box. If no problems are found, the analysis is
boxed in green. Problems are boxed in red and a detailed explanation is available.

"Delta Y on transmit is too small"
Description
The difference between the maximum voltage on the Y line and the minimum
voltage on the Y line must be > 1.88 volts during transmit.
The difference between the maximum voltage on the Y line and the minimum
voltage on the Y line must be > 1.88 volts during transmit.
Possible Cause
This problem can be caused by a faulty network driver in the control system or by a
short circuit between the Y line and either power or ground in the network wiring.
To verify if this problem is due to a faulty network driver, disconnect all network
wires from your control system and repeat the test. If you receive this message again,
you have a problem with your control system. If not, there is a probable short circuit
in your network wiring.
