Display of all measured values simultaneously.
The trigger section of the DS1054Z offers no less than 15 different trigger functions, such as pattern, time-out, window, delay, and also trigger capabilities for the supported serial protocols. The device has an internal sample memory of 24 Mpts. This is quite large, but just like with the A/D-converter, this memory also needs to be divided over the active number of channels. Even then, the capacity is still more than sufficient.

Rigol has done its best to accommodate a whole host of measurement functions in this device. Using the buttons on the left, you can quickly select from 32 parameters of which the measurement values (max. 5 at a time) then appear at the bottom of the image. In addition, there is a "normal" frequency counter. You can also choose to display 20 parameters at the same time. And there is a static function that shows the deviations over a number of periods for up to 5 parameters. You can also take cursor measurements, both automatically and manually.

Under the Math button, we find a large number of mathematical operations ranging from a simple summation to logarithm, exponent, integrate, and differentiate. This list also includes the FFT function. This can be used to display the frequency spectrum of a signal. A nice extra, but I had some trouble to set all parameters in such a way that a usable picture appeared. Rigol can tinker with that in the software.

The DS1054Z also offers a lot of extras, particularly for this price. Above, I've only described a few things that I've tried or that I've noticed. It is of course also possible to connect the oscilloscope to a computer and control it from the PC. On the Rigol website, the Windows programs UltraSigma and UltraScope are available for this purpose.

Conclusion

Decoding of I²C is standard.
The Rigol DS1054Z is a versatile oscilloscope, especially now that it comes with software extras. Although it has been on the market for several years, it can still easily compete with newer devices in this price range. For €400, you get a reliable device with four channels and a lot of features that you will enjoy for years to come.
