Abstract

A method for performing a Bus autoset function is described. A maximum amplitude of an analog signal is detected. The analog signal is converted into a logical signal. A frame in the logical signal is detected. A scale of an output unit is set such that the whole frame is output. Further, a measurement device is described.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1 . A method for performing a Bus autoset function, with the following steps:
detecting a maximum amplitude of an analog signal; converting the analog signal into a logical signal; detecting a frame in the logical signal; and setting a scale of an output unit such that the whole frame is output.

2 . The method according to claim 1 , wherein the whole content of a frame is displayed on a display of the measurement device.

3 . The method according to claim 1 , wherein a trigger level is set.

4 . The method according to claim 3 , wherein the trigger level is set prior to the logic conversion.

5 . The method according to claim 1 , wherein an actuation of the autoset function is detected at the beginning.

6 . The method according to claim 1 , wherein an autoset function is initiated initially by the user.

7 . The method according to claim 6 , wherein the autoset function is initiated by actuating a corresponding button of the measurement device.

8 . The method according to claim 1 , wherein a measurement device mode set is detected at the beginning.

9 . The method according to claim 1 , wherein a Bus decode mode is initiated initially by the user.

10 . The method according to claim 9 , wherein the Bus decode mode is initiated by actuating a corresponding button of the measurement device.

11 . The method according to claim 1 , wherein it is verified at the beginning if the autoset function is enabled and the measurement device mode is set to a Bus decode mode.

12 . The method according to claim 1 , wherein the analog signal is decoded.

13 . A measurement device comprising a processing unit that is configured to perform a method for performing a Bus autoset function, with the following steps:
detecting a maximum amplitude of an analog signal; converting the analog signal into a logical signal; detecting a frame in the logical signal; and setting a scale of an output unit such that the whole frame is output.

14 . The measurement device according to claim 13 , wherein the measurement device comprises a display that is configured to display an output of the processing unit.

15 . The measurement device according to claim 13 , wherein the measurement device is an oscilloscope.
