Operating the E5402A, E5405A, and E5406A-Pro Series Probes
Maintaining signal fidelity to the logic analyzer is critical if
the analyzer is to accurately capture data. One measure of a
system's signal fidelity is to compare V
step inputs. For the following graphs, V
logic analyzer probe tip. Eye Scan was used to measure V
the signal seen by the logic analyzer. The measurements
were made on a mid- bus connection to a 50Ω transmission
line load terminated at the receiver. These measurements
show the logic analyzer's response while using the E5402A,
E5405A, and E5406A- pro series soft touch probes.
