Multi-Eye Setup and Installation
The Multi Eye Measurement Tool does not require any additional software installation, as it is fully
integrated into the SDA software. However, depending on the specific mode of operation
selected, each of the three new modes of operation requires distinct instrument and channel
setups.
For example, the FSB mode requires setting up multiple channels to carry out the eye diagram
measurements, as described in the example below. The Gated Eye Diagram requires at least two
inputs: The Data and the Gate signal. The Transition Mode requires at least one input (the Data
Stream, but depending on the specific serial data standard, a clock input may also be required to
recover the clock information).
These signals (except for the strobes) are differential signals, so the use of differential probes is
often required to carry out the measurements. As with any high-speed precision measurements,
all probes and SMA cables should be calibrated and deskewed prior to any data collection.
