Problems solved by technology
[0005] However, there are inherent disadvantages, difficulties and unreliability associated with traditional comparison methods for video signals
Configuring multiple video waveform monitors to have the same measurement display using identical settings is tedious and error-prone, as measurement displays most often require multiple parameters to be set including filters, component selections, gain settings, etc.
Furthermore, the comparison of the previously acquired display with the live measurement display is also prone to confusion or error and is unreliable
This method inevitably loses the dynamic characteristics of the video signal

Embodiment Construction
[0028] A test and measurement instrument capable of dual simultaneous inputs, such as a video waveform monitor, can simultaneously and independently perform independent monitoring and measurement tasks on two or more inputs. Embodiments of the present invention provide a special mode of simultaneous input where measurement views and / or configuration parameters are synchronized across multiple signal and input channels. In other words, rather than individually configuring each measurement view of each respective input channel and thus going through the tedious and error-prone attempt of matching multiple configuration parameters on different input signals, embodiments of the present invention synchronize one input channel The comparison and analysis of different video signals, audio signals, time code signals, auxiliary data signals or other electrical signals is significantly simplified.
[0029] Embodiments of the invention may include test and measurement instruments. Test ...

The invention relates to a test and measurement device, a system, and a method for providing synchronized measurement views. Embodiments of the invention include a test and measurement device, system, and method for synchronizing measurement views and configuration parameters across multiple input channels or devices. A method includes receiving signals under test associated with multiple input channels of the test and measurement instrument or with multiple devices, selecting a measurement view of one input signal or device, receiving a synchronized view enable preference from a user control interface, and synchronizing the measurement view or configuration parameters of the other signals or devices with what was chosen on the first signal or device. A test and measurement instrument includes input terminals to receive the input signals, a user control interface to receive input from an operator, a display to provide measurement information about the input signals, and a synchronization control unit to synchronize measurement views and / or configuration parameters between the inputs or devices.
Description
technical field [0001] The present invention relates to the field of test and measurement, in particular to a test and measurement device, system and method for providing synchronized measurement views. Background technique [0002] Test and measurement instruments are essential for analyzing the quality of electrical signals. This instrument allows a variety of industries to develop and test new products, maintain quality control, and deliver high-value products and services. Industries such as computer, electronics, video, entertainment, and industrial manufacturing, among others, rely heavily on the ability to efficiently test and analyze electrical signals. [0003] For example, in the video production and broadcast industries, video signal analysis and comparison are critical to the successful delivery of high-quality video. Multiple cameras are often necessary and it can be difficult to adjust them to have the same brightness and chroma levels for the video recording...
