Oscilloscope's integrated generator takes on complex tests

An integrated arbitrary waveform and pattern generator enables R&S RTO2000 and R&S RTE oscilloscopes to deliver test signals on two analogue and eight digital channels, making it possible to test complex circuits in a minimum of space using a single instrument. Even fully automated compliance tests can be performed. The RTO-B6/R&S RTE-B6 arbitrary waveform and pattern generator options from Rohde & Schwarz operate via controls that are completely integrated into the oscilloscope GUI.

Each of the two analogue channels on the generator has a bandwidth of 100MHz and can be operated in any of four modes: as a function generator, as a modulation generator, in sweep mode, or for replay of arbitrary waveforms.

The waveform generator's data rate of 500Msample/s and resolution of 14 bits make it well suited for development tasks. It can be used to characterise components such as differential amplifiers, for example.

The pattern generator can be used to output individually configured digital signals on up to eight channels. With a data rate of up to 40Msample/s, it can generate clock and bus signals such as SPI, for example.

A typical application is measuring the settling time of power amplifiers after using a serial bus telegram to set the parameters. Users can operate the fully integrated generator via the large touchscreen. A graphical display clearly shows all settings for the waveforms to be generated.

Arbitrary waveforms can also be taken from one of the oscilloscope channels. For example, acquired bus telegrams can be copied into the arbitrary waveform generator at the touch of a button. The R&S RTO-B6 option can also be used for automating Ethernet compliance tests.

The integrated arbitrary waveform generator automatically produces the required interference signals, simplifying test setup and execution.

The integrated R&S RTO-B6/R&S RTE-B6 arbitrary waveform and pattern generator hardware option is now available from Rohde & Schwarz for oscilloscopes from the R&S RTO2000 and R&S RTE series.
