Abstract

An interleaved acquisition system for acquiring a high bandwidth input signal, comprising a first acquisition and quantizer unit, a second acquisition and quantizer unit as well as a trigger unit. The first and second acquisition and quantizer units are configured to receive a respective interleaved digitized input signal, to acquire the respective interleaved digitized input signal, to quantize the respective interleaved digitized input signal, and to output a respective quantized interleaved digitized input signal. The trigger unit is configured to receive the respective quantized interleaved digitized input signals from the first and second acquisition and quantizer units. The trigger unit is further configured to de-interleave the respective quantized interleaved digitized input signals. The trigger unit is configured to generate a de-interleaved quantized digitized input signal. The trigger unit is also configured to detect an event in the de-interleaved quantized digitized input signal. Further, a method of acquiring a high bandwidth input signal is described.

First claim

1 . An interleaved acquisition system for acquiring a high bandwidth input signal, comprising a first acquisition and quantizer unit, a second acquisition and quantizer unit, and a trigger unit,
said first acquisition and quantizer unit being configured to receive a first interleaved digitized input signal, said first acquisition and quantizer unit being configured to acquire said first interleaved digitized input signal, said first acquisition and quantizer unit being configured to quantize said first interleaved digitized input signal, and said first acquisition and quantizer unit being configured to output a first quantized interleaved digitized input signal; said second acquisition and quantizer unit being configured to receive a second interleaved digitized input signal, said second acquisition and quantizer unit being configured to acquire said second interleaved digitized input signal, said second acquisition and quantizer unit being configured to quantize said second interleaved digitized input signal, and said second acquisition and quantizer unit being configured to output a second quantized interleaved digitized input signal; and said trigger unit being configured to receive said first quantized interleaved digitized input signal from said first acquisition and quantizer unit, said trigger unit being configured to receive said second quantized interleaved digitized input signal from said second acquisition and quantizer unit, said trigger unit being configured to de-interleave said first quantized interleaved digitized input signal and said second quantized interleaved digitized input signal, said trigger unit being configured to generate a de-interleaved quantized digitized input signal based on said first quantized interleaved digitized input signal and said second quantized interleaved digitized input signal, and said trigger unit being configured to detect an event in said de-interleaved quantized digitized input signal.

2 . The interleaved acquisition system according to claim 1 , wherein said first quantized interleaved digitized input signal and said second quantized interleaved digitized input signal are directly forwarded to said trigger unit in parallel.

3 . The interleaved acquisition system according to claim 1 , wherein at least one of said first acquisition and quantizer unit and said second acquisition and quantizer unit is configured to quantize by at least one threshold.

4 . The interleaved acquisition system according to claim 1 , wherein at least one of said first acquisition and quantizer unit and said second acquisition and quantizer unit is configured to quantize by at least two thresholds.

5 . The interleaved acquisition system according to claim 4 , wherein said at least two thresholds are not equidistant.

6 . The interleaved acquisition system according to claim 1 , wherein said trigger unit is implemented on a separate chip with respect to at least one of said first acquisition and quantizer unit and said second acquisition and quantizer unit.

7 . The interleaved acquisition system according to claim 1 , wherein said first acquisition and quantizer unit is implemented on a separate chip with respect to said second acquisition and quantizer unit.

8 . The interleaved acquisition system according to claim 1 , wherein said first acquisition and quantizer unit and said second acquisition and quantizer unit are assigned to separate channels.

9 . The interleaved acquisition system according to claim 1 , wherein said interleaved acquisition system is implemented in a single-housed device.

10 . The interleaved acquisition system according to claim 9 , wherein said single-housed device is an oscilloscope or a spectrum analyzer.

11 . A single-housed device comprising the interleaved acquisition system according to claim 1 .

12 . A method of acquiring a high bandwidth input signal, comprising:
receiving a first interleaved digitized input signal via a first acquisition and quantizer unit; acquiring said first interleaved digitized input signal via said first acquisition and quantizer unit; quantizing said first interleaved digitized input signal via said first acquisition and quantizer unit; outputting a first quantized interleaved digitized input signal via said first acquisition and quantizer unit; receiving a second interleaved digitized input signal via a second acquisition and quantizer unit; acquiring said second interleaved digitized input signal via said second acquisition and quantizer unit; quantizing said second interleaved digitized input signal via said second acquisition and quantizer unit; outputting a second quantized interleaved digitized input signal via said second acquisition and quantizer unit; receiving, via a trigger unit, said first quantized interleaved digitized input signal and said second quantized interleaved digitized input signal; de-interleaving, via said trigger unit, said first quantized interleaved digitized input signal and second quantized interleaved digitized input signal; generating, via said trigger unit, a de-interleaved quantized digitized input signal based on said first quantized interleaved digitized input signal and second quantized interleaved digitized input signal; and detecting, via said trigger unit, an event in said de-interleaved quantized digitized input signal.

13 . The method according to claim 12 , wherein said first quantized interleaved digitized input signal and said second quantized interleaved digitized input signal are directly forwarded to said trigger unit in parallel.
