Abstract

A system to create periodic pulse sequences with defined absolute phase comprises a phase coherent analyzer and a pulse generator. The phase coherent analyzer and the pulse generator are connected with each other. The pulse generator has a clock input connected to the analyzer for receiving a clock signal from the analyzer. The system comprises a trigger line via which a marker signal is provided to at least one of the analyzer and the pulse generator. The marker signal temporally aligns an output signal of the pulse generator with a measurement process of the analyzer. Further, a method of creating periodic pulse sequences with defined absolute phase is described.

First claim

The invention claimed is:

1. A system to create periodic pulse sequences with defined absolute phase, the system comprising a phase coherent analyzer and a pulse generator, the phase coherent analyzer and the pulse generator being connected with each other, the pulse generator having a clock input connected to the analyzer for receiving a clock signal from the analyzer, the system comprising a trigger line via which a marker signal is provided to at least one of the analyzer and the pulse generator, the marker signal temporally aligning an output signal of the pulse generator with a measurement process of the analyzer such that the system is a coherent one that is configured to create periodic pulse sequences with defined absolute phase.

2. The system according to claim 1 , wherein the pulse generator has a periodic sequence that defines on which cycles of the clock signal the pulse generator generates a pulse.

3. The system according to claim 2 , wherein the periodic sequence is either pre-set or configurable by a user.

4. The system according to claim 2 , wherein the periodic sequence relates to a divider mode, a pseudo random binary sequence mode or a custom periodic sequence mode.

5. The system according to claim 1 , wherein the marker signal is an analyzer marker signal issued from the analyzer, the analyzer marker signal internally synchronizing at least one measurement process of the analyzer.

6. The system according to claim 1 , wherein the pulse generator is configured to receive the marker signal and to compare the marker signal to the clock signal.

7. The system according to claim 1 , wherein the marker signal corresponds to a trigger signal issued from the pulse generator.

8. The system according to claim 1 , wherein the analyzer is configured to receive the marker signal from the pulse generator.

9. The system according to claim 1 , wherein the marker signal is provided by an external device.

10. The system according to claim 1 , wherein the pulse generator is a comb generator.

11. The system according to claim 1 , wherein the pulse generator and the analyzer are integrated in a common device.

12. A method of creating periodic pulse sequences with defined absolute phase, with the following steps:
Establishing a connection between an analyzer and a pulse generator,
Providing a clock signal from the analyzer to the pulse generator,
Establishing a trigger line to at least one of the analyzer and the pulse generator, and
Providing a marker signal that temporally aligns an output signal of the pulse generator with a measurement process of the analyzer in order to create periodic pulse sequences with defined absolute phase.

13. The method according to claim 12 , wherein the pulse generator receives the marker signal and the pulse generator compares the marker signal to the clock signal.

14. The method according to claim 12 , wherein the marker signal is an analyzer marker signal issued from the analyzer, the analyzer marker signal internally synchronizing at least one measurement process of the analyzer.

15. The method according to claim 12 , wherein the marker signal corresponds to a trigger signal issued from the pulse generator.

16. The method according to claim 12 , wherein the analyzer receives the marker signal from the pulse generator.

17. The method according to claim 12 , wherein the analyzer is temporally aligned in post-processing.

18. The method according to claim 12 , wherein the marker signal is provided by an external device.

19. A system to create periodic pulse sequences with defined absolute phase, the system comprising a phase coherent analyzer and a pulse generator, the phase coherent analyzer and the pulse generator being connected with each other, the pulse generator having a clock input connected to the analyzer for receiving a clock signal from the analyzer, the system comprising a trigger line via which a marker signal is provided to at least one of the analyzer and the pulse generator, the marker signal temporally aligning an output signal of the pulse generator with a measurement process of the analyzer, and wherein the marker signal corresponds to an electrical pulse that relates to a direct alignment, an alignment with a predefined delay or rather an alignment that depends on the clock signal.
