Cascading with CATC SYNC Expansion Card
Teledyne LeCroy Corporation
Note:
At power‐on, the Analyzer initializes itself in approximately ten seconds and performs an
exhaustive self‐diagnostic that lasts about five seconds. If the diagnostics fail, call Teledyne
LeCroy.
5. Complete Analyzer setup in the “Application Startup” section (See
WARNING:
Do not change from USB to Ethernet, or back, without power cycling the Analyzer.
Note:
Disconnection of USB or Ethernet during capture or uploading of trace data is not supported,
and may cause the software to malfunction or crash.

Cascading with CATC SYNC Expansion Card
You can daisy chain two Analyzers, if they both have a CATC SYNC port:
Voyager M3 and M3i require a CATC Sync Expansion Card for cascading.
Voyager M3x and Advisor T3 have built‐in CATC SYNC ports and only requires a
cross‐connect (M3x) or an octopus cable (AT3) accessory kit.
After Analyzers are connected, recording will start simultaneously and triggers will occur
simultaneously, with synchronized timestamps. This feature can be "soft" disconnected
by modifying the CATC Sync options on the Recording Options General tab.
You must select both Analyzers in the Device List dialog
(see
Important: If you are using other analyzers (NOT USB!) in your daisy chain (this would
include PCIe, DDR, SAS, SAS, FC, net) and do not wish to use the daisy chaining feature of
synchronized recordings, you must UNPLUG the cable! If you do not unplug, the electrical
signal prevents recording on all Analyzers.
Note:
In this software version, daisy chained recording only works if you use two Voyagers OR two
Advisor T3s. You cannot use one of each. Also, you must enable 3.0 Auto‐Detect/Termination
mode. Manual control does not work.
3.4.1
Capturing USB 2.0 traffic with CATC Sync or Cross Sync
When using Cross Sync or CATC Sync and capturing USB 2.0 traffic, attach the USB 2.0
capturing analyzer device at the OUT connector at the beginning of the CATC SYNC chain.
Otherwise, the timestamps will not be synchronized.
The USB 2.0 clock for any downstream Voyager or Advisor T3's will not be synchronized
with the upstream CATC‐Sync devices, unless there is also 3.0 traffic on the downstream
analyzer(s). In cases of CATC‐Syncing with USB analyzers capturing 3.0 traffic, all boxes will
have the correct synchronized timestamps.
