Abstract

A measurement device is provided. The measurement device comprises a display configured to display a measurement trace, an analyzing unit configured to analyze a subset of measurement data represented by the measurement trace on the basis of at least one target measurement parameter, and a post-processing unit configured to search for the at least one target measurement parameter.

First claim

What is claimed is:

1. A method for controlling a measurement device, wherein the method comprises the steps of:
displaying a measurement trace on a touchscreen display of the measurement device,
analyzing a subset of measurement data represented by the measurement trace on the basis of at least one target measurement parameter,
searching for the at least one target measurement parameter,
running a synchronization routine on measurement settings, wherein the synchronization routine attempts to lock on the target measurement parameter via correlation with a reference waveform and recovery of a modulated signal symbol rate in the case that a spectrum is displayed, or via correlation with a reference waveform and a burst detection algorithm in the case that a magnitude is displayed,
executing a calculation, in parallel while the measurement settings are adjusted, in order to check if certain criteria are fulfilled by the current measurement settings,
snapping the measurement settings, if said criteria are fulfilled,
finding possible snap positions corresponding to the snapped measurement settings in advance by analyzing over an available time and/or bandwidth, and graphically displaying said snap positions,
based on a double tap touch gesture with respect to the touchscreen display, causing a search for a signal analysis to be performed in a localized region around the position of the double tap touch gesture,
wherein the double tap touch gesture comprises two successive touches,
wherein the subset of measurement data is determined on the basis of at least one user measurement parameter set by at least one user input, and
wherein the at least one user measurement parameter comprises at least one of bandwidth, acquisition time, or trigger offset.

2. The method according to claim 1 , wherein the at least one user input comprises at least one of a keyboard input, a mouse input, a touch gesture, and a voice control command.

3. The method according to claim 1 , wherein the method further comprises the step of automatically setting the at least one target measurement parameter in the display of the measurement device and/or wherein the method further comprises the step of setting the at least one target measurement parameter on the basis of at least one reasonable analysis result especially in the form of synchronization, error vector magnitude, minimized error vector magnitude, maximum correlation or power maximum.

4. The method according to claim 1 , wherein the at least one target measurement parameter comprises at least one of target bandwidth, target center frequency, target acquisition time, target trigger offset or level.

5. The method according to claim 1 , wherein the method further comprises the step of deriving the at least one target measurement parameter from the at least one user measurement parameter.

6. A measurement device comprising:
a touchscreen display configured to display a measurement trace,
an analyzing unit configured to analyze a subset of measurement data represented by the measurement trace on the basis of at least one target measurement parameter, and
a post-processing unit configured to search for the at least one target measurement parameter,
wherein a synchronization routine runs on measurement settings, wherein the synchronization routine attempts to lock on the target measurement parameter via correlation with a reference waveform and recovery of a modulated signal symbol rate in the case that a spectrum is displayed, or via correlation with a reference waveform and a burst detection algorithm in the case that a magnitude is displayed,
wherein the analyzing unit and/or the post-processing unit is configured to execute a calculation, in parallel while the measurement settings are adjusted, in order to check if certain criteria are fulfilled by the current measurement settings,
wherein the analyzing unit and/or the post-processing unit is configured to snap the measurement settings, if said criteria are fulfilled,
wherein the analyzing unit is configured to find possible snap positions corresponding to the snapped measurement settings in advance by analyzing over an available time and/or bandwidth, whereby the display is configured to graphically display said snap positions, and
based on a double tap touch gesture with respect to the touchscreen display, the analyzing unit is configured to cause a search for a signal analysis to be performed in a localized region around the position of the double tap touch gesture,
wherein the double tap touch gesture comprises two successive touches,
wherein the subset of measurement data is determined on the basis of at least one user measurement parameter set by at least one user input, and
wherein the at least one user measurement parameter comprises at least one of bandwidth, acquisition time, or trigger offset.

7. The measurement device according to claim 6 , wherein the at least one user input comprises at least one of a keyboard input, a mouse input, a touch gesture, and a voice control command and/or wherein the at least one user measurement parameter comprises at least one of bandwidth, center frequency, acquisition time, trigger offset or level.

8. The measurement device according to claim 6 ,
wherein the analyzing unit is further configured to automatically set the at least one target measurement parameter in the display of the measurement device, and/or
wherein the post-processing unit is further configured to automatically set the at least one target measurement parameter in the display of the measurement device.

9. The measurement device according to claim 6 , wherein the at least one target measurement parameter comprises at least one of target bandwidth, target center frequency, target acquisition time, target trigger offset or level.

10. The measurement device according to claim 6 ,
wherein the analyzing unit is further configured to set the at least one target measurement parameter on the basis of at least one reasonable analysis result especially in the form of synchronization, error vector magnitude, minimized error vector magnitude, maximum correlation or power maximum, and/or
wherein the post-processing unit is further configured to set the at least one target measurement parameter on the basis of at least one reasonable analysis result especially in the form of synchronization, error vector magnitude, minimized error vector magnitude, maximum correlation or power maximum.

11. The measurement device according to claim 6 ,
wherein the analyzing unit is further configured to derive the at least one target measurement parameter from the at least one user measurement parameter, and/or
wherein the post-processing unit is further configured to derive the at least one target measurement parameter from the at least one user measurement parameter.
