Abstract

An arbitrary waveform sequencer device for playing a list of at least a first and a second arbitrary waveform file in a sequence is provided. The arbitrary waveform sequencer device comprises a list increment condition control unit configured to control an increment from the first to the second arbitrary waveform file as a function of an increment condition, and a transition control unit configured to control a timing of the increment.

First claim

What is claimed is:

1. An arbitrary waveform sequencer device for playing a list of at least a first and a second arbitrary waveform file in a sequence, the arbitrary waveform sequencer device comprising:
a list increment condition control unit configured to control playing of the first arbitrary waveform file and subsequently playing the second arbitrary waveform file as a function of an increment condition, and
a transition control unit configured to control a timing of the playing of the first arbitrary waveform file and subsequently playing the second arbitrary waveform.

2. The arbitrary wave sequencer device according to claim 1 ,
wherein the increment condition comprises at least one of a predefined play time, a number of repeat cycles of the first and/or the second arbitrary waveform file, a play of the list until a predefined event is detected, an event in a signal received by the arbitrary waveform sequencer device, which triggers playing the second arbitrary waveform file after the first arbitrary waveform file, or any combination thereof.

3. The arbitrary waveform sequencer device according to claim 1 ,
wherein the timing comprises at least one of an immediate transition from the first to the second arbitrary waveform file, a predefined marker trace signal comprising at least one timing marker, or any combination thereof.

4. The arbitrary waveform sequencer device according to claim 1 ,
wherein a sampling rate of the first and the second arbitrary waveform file is different.

5. The arbitrary waveform sequencer device according to claim 4 ,
wherein the arbitrary waveform sequencer device further comprises a resampling unit configured to match the sampling rate of the first and the second arbitrary waveform file.

6. The arbitrary waveform sequencer device according to claim 1 ,
wherein at least one of the first and the second arbitrary waveform file comprises intelligence quotient (IQ) data.

7. The arbitrary waveform sequencer device according to claim 6 ,
wherein the IQ data form messages of a communication standard.

8. The arbitrary waveform sequencer device according to claim 6 ,
wherein the IQ data model signal characteristics.

9. An arbitrary waveform sequencer method for playing a list of at least a first and a second arbitrary waveform file in a sequence, the arbitrary waveform sequencer method comprising the steps of:
controlling playing, by way of a list increment condition control unit of an arbitrary waveform sequencer, of the first arbitrary waveform file and subsequently playing the second arbitrary waveform file as a function of an increment condition, and
controlling, by way of a transition control unit of the arbitrary waveform sequencer, a timing of the playing of the first arbitrary waveform file and subsequently playing the second arbitrary waveform.

10. The arbitrary wave sequencer method according to claim 9 ,
wherein the increment condition comprises at least one of a predefined play time, a number of repeat cycles of the first and/or the second arbitrary waveform file, a play of the list until a predefined event is detected, an event in a signal received by the arbitrary waveform sequencer device, which triggers playing the second arbitrary waveform file after the first arbitrary waveform file, or any combination thereof.

11. The arbitrary waveform sequencer method according to claim 9 ,
wherein the timing comprises at least one of an immediate transition from the first to the second arbitrary waveform file, a predefined marker trace signal comprising at least one timing marker, or any combination thereof.

12. The arbitrary waveform sequencer method according to claim 9 ,
wherein a sampling rate of the first and the second arbitrary waveform file is different.

13. The arbitrary waveform sequencer method according to claim 12 ,
wherein the arbitrary waveform sequencer method further comprises the step of matching the sampling rate of the first and the second arbitrary waveform file.

14. The arbitrary waveform sequencer method according to claim 9 ,
wherein at least one of the first and the second arbitrary waveform file comprises intelligence quotient (IQ) data.

15. The arbitrary waveform sequencer method according to claim 14 ,
wherein the IQ data form messages of a communication standard.

16. The arbitrary waveform sequencer method according to claim 14 ,
wherein the IQ data model signal characteristics.
