Voltcraft’s latest oscilloscope series

Their compact lightweight design together with either two or four analogue channels, and a bandwidth of 70 to 250MHz make these products well suited to field work and classroom alike. A built-in HMDI port allows mirroring display content to large screens.

Voltcraft also provides models featuring a function generator and a logic analyser which boosts their range of uses even more. 

No more fiddling with selectors and pressing buttons is required; all models of Voltcraft’s DOV series come with an easy-to-use touchscreen that supports gesture control, just like a smartphone. “That doesn’t mean you have to use it though,” said Harald Lehner, Product Manager, Voltcraft. “Goes without saying that DOV models continue to feature selectors and buttons, to provide an additional, or alternative, mode of operation.”     

While the eight new DOV models might not look too much different from each other, each has its very own set of specifications, to address different user needs. Two of the models have bandwidths of 70 and 100MHz, respectively, with each being available as a 2-channel and 4-channel version. An AWG function generator is what tells the 125MHz and 250MHz models apart: all of them provide four analogue channels but only one of the 125MHz versions and Voltcraft’s DOV 2504F LA flagship product feature the function generator.

However, all four models come with a 16-channel logic analyser that is compatible with the Voltcraft DOV-PP116 16-chan logic analyser probe which needs to be ordered separately.  

"We designed these products with the specific requirements of their intended users in mind,” said Lehner. This is why the new DOV series offers a whole range of technical strongpoints that are part of the package, and include a 12-bit A-D converter as well as USB, LAN and HDMI ports. All Voltcraft’s digital DOV oscilloscopes operate at a sampling rate of 1.25 Gsa per second. Their real-time wave form capture rate is 50,000 wfms per second. This goes up to 700,000 wfms per second when using segmented memory which allows visualising irregular interference signals. Time resolution ranges from 1 ns/div to 1000 s/div.

Additionally, the products offer an exhaustive set of trigger functions and data bus decoders (RS232/UART, I2C, SPI, LIN, CAN), boosting their overall versatility. Also, 4-channel versions come with 4 probes.  

As an expansion to their analysis package, Voltcraft oscilloscopes use Fast Fourier Transformation (FFT) to convert signals into their individual spectral components. A wide range of mathematical and cursor-related functions enables fast data evaluation across all channels. In terms of QA, a pass/fail function allows comparing a signal to pre-set waveforms. If signal and pre-set don’t match, this triggers a pulse being outputted via the BNC connector on the back panel.   

Last but not least, the products feature an HDMI port on the back panel that enables mirroring the oscilloscope’s display content on any large screen, TV or monitor. This comes in particularly handy in team meetings, the classroom and vocational training.
