DPO2AUTO

The DPO2AUTO is a plug-in application module that adds automotive serial bus support to Tektronix MSO2000, DPO2000, MSO2000B and DPO2000B series oscilloscopes. With it installed the oscilloscope can trigger on packet-level content on CAN and LIN buses and show the bus as decoded packets.

Besides triggering it enables bus views, packet decoding, search through the record for bus events and an event table that lists each decoded packet with a time stamp. On the 2000B series, CAN triggering covers start of frame, frame type, identifier, data, end of frame, missing ACK and bit stuffing errors at up to 1 Mb/s; LIN triggering covers sync, identifier, data, wakeup and sleep frames and sync, parity or checksum errors.

The module goes into one of the two application module slots behind the small window at the top right of the front panel; up to two modules can be fitted at once, and the features are only available while the module stays installed. Tektronix no longer sells the MSO/DPO2000B series; late in the series the DPO2AUTO was offered only as part of the DPO2BND bundle (DPO2AUTO, DPO2COMP and DPO2EMBD).
