A test arrangement and a method for controlling a measurement apparatus are provided. The measurement apparatus, in particular the triggering of the measurement apparatus is controlled by a state machine. If a desired state for triggering the measurement apparatus is not entered within a predetermined time period, the conditions for triggering the measurement apparatus can be adapted. For example, a required state for triggering can be changed or an automated triggering can be initiated.

Measurement apparatus and method for controlling a measurement apparatus

The present invention provides to a processing of data samples by an arrangement comprising a signal processing chip for executing predetermined operations and a processor for executing any kind of software code. In particular, it is not only possible that the general purpose processor, which executes the software code can process results from the signal processing chip, but also the signal processing chip can receive the results of the general purpose processor for applying further operations. In this way, the flexibility and efficiency of the processing can be further improved.

Device and method for processing data samples

A measurement system has an analog channel comprising an analog-to-digital converter for converting an external analog input signal into a corresponding digital input signal, an external trigger input for receiving an external trigger signal comprising a comparator configured to compare the external trigger signal against a trigger threshold signal for generating a binary trigger signal, and a digital signal processing unit. The digital signal processing unit comprises a digital trigger unit configured to receive the digital input signal and to generate at least one trigger event signal based on the digital input signal, and a trigger logic unit configured to receive the at least one trigger event signal and the binary trigger signal to generate a combined trigger signal. Further, a method for generating a trigger signal for a measurement system is described.

A method for operating an oscilloscope is described, wherein a waveform axis scale input value is detected. Further, a record length input value is detected. An oscilloscope operating point is determined relative to at least one predetermined operating mode limit. In addition, a method for operating an oscilloscope as well as an oscilloscope are described.

A method for generating an output signal having predetermined jitter characteristics is disclosed. A first signal is generated via a first signal generator module. A second signal is generated via a second signal generator module. The first signal is pulse position modulated by the second signal, thereby generating a modulated signal having predetermined jitter characteristics. An output signal having predetermined jitter characteristics is generated based on the modulated signal. Moreover, a signal generator for generating an output signal having predetermined jitter characteristics is disclosed.

Method for generating an output signal having predetermined jitter characteristics

A measurement device for measuring at least one signal generates a first trigger impulse upon detection of a first trigger condition in at least one signal to be measured. It stores for the at least one signal multiple segments each containing the detected first trigger condition upon generation of the first trigger impulse in an acquisition memory. A second trigger impulse is generated upon detection of a second trigger condition in the multiple segments of the at least one signal stored in the acquisition memory. For the at least one signal the segments containing the detected second trigger condition are displayed upon generation of the second trigger impulse on a display unit.

Measurement device and method for measuring at least one signal

An oscilloscope comprises at least one analog input channel configured to receive and process an analog input signal, at least one digital input channel configured to receive and process a digital input signal, and a trigger unit. Said trigger unit is connected with said at least one analog input channel and said at least one digital input channel. Said trigger unit is configured to detect predetermined trigger events in both said analog input signal and said digital input signal. Said trigger unit further is configured to control data acquisition based on a combination of at least two trigger events detected in said analog input signal and said digital input signal.

Oscilloscope and method for operating an oscilloscope

A method for marking a signal edge, which has been removed from at least one decimated binary signal after the decimation of an associated binary signal, within the decimated binary signal, establishes successive signal portions of the respective binary signal, in each case with a number of sampled values corresponding to a decimation factor of the decimation. It detects a signal edge removed through decimation from each signal portion if the number of signal edges determined in each signal portion of the respective binary signal is greater than one. Then, the sampled values of the respective decimated binary signal are determined through decimation of the sampled values of the associated binary signal with the decimation factor, and the removed signal edge at the sampling time of the decimated binary signal which corresponds to the signal portion of the associated binary signal with the signal edge removed through decimation is marked.

Method and a device for preventing signal-edge losses

A measuring device for the measurement of differential signals including a real-time portion, which contains two probes, a signal adder and a triggering device. The probes each record a partial signal of a differential signal. The signal adder adds the partial signals to form a differential signal. The triggering device implements a triggering on the basis of the differential signal.
