Making a Measurement Using the PM50 and the Known Pattern with Marker Tool
The tool defaults to a Single Rate Fibre Channel setup. The description covers a basic measurement and
configuration.
• Connect a repeating data signal to a Channel with the Pattern Marker option. A channel with the
Pattern Marker option will be labeled "Pattern Marker Enabled" on the front of the
SIA-3000™.
• Select "Pattern Options".
• Select “Load Pattern” to load the pattern (*.ptn) file. Note: “Learn Pattern” cannot be used unless
an external pattern marker is supplied.
• Select the "Acquire Options" button.
• Select the appropriate channel using the Add/Delete button.
• Select the Pattern Marker option (check box) from the "Arm Number" menu box.
• Choose the –3dB corner frequency—default is 637kHz for 1x Fibre Channel (1274kHz for 2xFC).
• Select the "Arm Setup" button.
• Select either Pattern Match or Edge Count in the “Ptn Mkr Mode” field. For most setups, Edge count
should be used. If pattern match is selected then choose the appropriate standard.
Edge Count mode counts a number of edges and then generates the marker. By choosing the
pattern, the number of rising edges in that pattern is automatically calculated and used as the
number of edges to count.
