Abstract: A test and measurement instrument includes an acquisition memory and a processor structured to store a stream of sampled incoming data samples in the acquisition memory. As the memory fills, the instrument automatically decimates either the data samples already stored in the acquisition memory, the incoming data samples, or both. The instrument may also store two copies of the incoming data samples, one at an increased decimation rate. The two copies are tied together with a timestamp or using other methods. The more highly decimated copy may be used to produce a video output of the stored data samples, saving the instrument from generating the video output from the larger sized sample.

Abstract: A method of capturing instrument data using a communications device includes sending an actuation signal to a camera to take a photograph of at least one instrument, one of either transmitting or receiving a trigger message between the communications device and the at least one instrument, storing the photograph in a memory on the communications device, determining associated information for the photograph, and transmitting the photograph, associated information and user information to a network.

Abstract: A method of capturing instrument data using a communications device includes recognizing an action performed by a user on the communication device, one of either transmitting or receiving a trigger message between the communications device and at least one instrument, storing instrument data in a memory on the at least one instrument, and transmitting the instrument data and user information to a network.

Abstract: Embodiments of the invention include an apparatus and method for displaying trigger frequency on a display of a test and measurement instrument. During each of a series of equal time intervals, a number of trigger events are counted. Each trigger event count is associated with a corresponding logical column of a trigger display window. The trigger event counts are written to memory locations associated with the corresponding logical columns of the trigger display window. Trigger frequency logic generates multiple trigger frequency indicators based on the trigger event counts. The trigger frequency indicators are displayed in the trigger display window to quickly and efficiently convey trigger density information to a user of the test and measurement instrument. The apparatus includes jitter reduction logic to reduce or eliminate unwanted jitter related to the trigger frequency indicators.
