Abstract
A signal sample trigger apparatus (206) comprises an input (302, 304), a processing resource (300, 500) coupled to the input (302, 304), and an output (306) coupled to the processing resource (300, 500). The processing resource (300, 500) is arranged to generate, when in use, a trigger signal (400, 600) in response to location increment information. The location increment information (402, 404, 602, 604) is received via the input (302, 304), and the trigger signal (400, 600) is provided via the output for triggering execution of a sample of an analogue signal.
Claims20
A signal sample trigger apparatus comprising:
- an input;
- a processing resource coupled to the input;
- and
- an output coupled to the processing resource;
- wherein
- the processing resource is arranged to generate, when in use, a trigger signal in response to a location increment signal, the location increment signal having a rising edge and a falling edge;
- the location increment signal corresponds to a repeating predetermined travel distance and is received via the input;
- and
- the trigger signal is provided via the output for triggering execution of a sample of a measurement signal, the trigger signal comprising a repeating series of pulses associated with the location increment signal including a first pulse and a second pulse:
- wherein
- the first pulse and the second pulse are generated in response to the rising edge of the location increment signal and the falling edge of the location increment signal, respectively.
A method of sampling a measurement signal, the method comprising:
- receiving a location increment signal corresponding to a repeating predetermined travel distance, the location increment signal having a rising edge and a falling edge;
- generating a trigger signal in response to the location increment signal, the trigger signal comprising a repeating series of pulses associated with the location increment signal including a first pulse and a second pulse;
- wherein
- the first pulse and the second pulse are generated in response to the rising edge of the location increment signal and the falling edge of the location increment signal, respectively;
- and
- sampling the measurement signal in response to the trigger signal.
