This allows users to see upper-level mapped protocol events within the trace eliminating the tedious process of manually decoding device specific commands. From Mass Storage to Communication Device Class (CDC), the Mercury T2C & T2P provide the most complete decoding of USB device transactions.

The Mercury solutions lead the industry in affordability offering comprehensive USB 2.0 test and analysis features. Starting at $995, the Mercury can be used virtually anywhere, extending beyond the lab environment over to the personal workstations of USB developers. Every engineer within a design team (hardware, software, and firmware) will appreciate the benefit of having a personal analyzer to fit their individual needs.

Featuring the industry-leading CATC Trace expert analysis software, the Mercury T2C & T2P provide an easy-to-use display that graphically decodes logical protocol events. All models of the Mercury include the same comprehensive decoding of the higher layer protocols which can be expanded to show the underlying transactions and packets.

Completely passive in design, the Mercury preserves real-world signaling and provides 100% faithful representation of traffic on the bus. Featuring a high-impedance, non-intrusive probe, the Mercury acts strictly as a "sniffer" and does not re-time the signal or significantly degrade the amplitude between the host and device. The Mercury T2C offers 256MB; while the Mercury T2P doubles the recording capacity to 512MB. Both systems can extend capacity with filtering, data truncation, and spool-to-disk capture for longer recording times. Fully compatible with USB Type-C standard, all Mercury models will ‘pass through’ SuperSpeed or Alternate-mode signaling without affecting their operation.
Isolating specific protocol events with real time triggering is essential to capture intermittent problems. Both the Mercury T2C & T2P provide sophisticated triggering with drag-and-drop selections for PID type, data patterns, standard requests, errors, and bus events. The Mercury provides 14 protocol error triggers with auto-detection of several additional post-capture errors. The ability to trigger & pinpoint specific bus conditions as they occur saves time during testing and debug.

The Power Tracker option monitors Vbus power draw and displays voltage graphically in a time line format. This power information is synchronized to the trace allowing users to verify power state transitions at the both the protocol and electrical layers. Completely transparent to the system-under-test, the Power Tracker samples VBUS and CC voltage during normal operations. It correlates these physical layer measurements with logical protocol layer events.

The CATC trace software includes a persistent timing display that provides one-click measurements between events. The bandwidth calculator provides full bus utilization metrics for any range of packets.

Teledyne LeCroy's USB software provides many mechanisms to measure and report on USB traffic. The Bus Utilization graphs packet length, bus usage by device and SCSI pending I/Os. Using the Traffic Summary window, users can evaluate statistical reports at a glance or navigate to individual packets, transactions or transfers.
Powerful search and reporting options allow users to quickly navigate to specific packets, errors and any data type within a trace file. The CATC Trace also supports filter and hide commands, to remove irrelevant data from the Trace for efficient viewing.


The Mercury T2P is also available with “SBU Capture” options allowing users to see DisplayPort Aux channel messages (USB-MCDP-M03-X) or Thunderbolt-3 low-speed communications (USB-MCTB-M03-X). Fully compatible with alt-mode devices that support DisplayPort 1.4, the DP capture mode decodes the essential back-channel communication for Type-C connections that utilize DP alt-mode. For Thunderbolt-3 developers, the Mercury T2P SBU capture option for Thunderbolt-3 decodes the essential link discovery, transmitter training and configuration phases which are transmitted over the low-speed (UART) back channel.
