Abstract:
1. A probe for use in a multiple probe acquisition system comprising: an acquisition system for acquiring and storing in response to a trigger signal an electrical signal from a device under test as digital data at a high rate; and a cable for transferring the digital data and the trigger signal from the probe acquisition system to a control and display platform at a low rate and for transferring power, control information and an external trigger signal from the control and display platform to the probe acquisition system; wherein the digital data comprises digitized data samples; wherein the acquisition system comprises: an analog-to-digital converter for converting the electrical signal to the digitized data samples; and a storage device for storing the digitized data samples in a recirculating manner; and wherein the acquisition system includes a trigger circuit for recognizing from the electrical signal a trigger event to generate the trigger signal for stopping storage of the digitized data samples in a recirculating storage device after a specified time interval.
