At Embedded World 2017, in March in Nuremberg, Germany, Rohde & Schwarz premiered its RTB2000 entry-level oscilloscope for education, R&D and manufacturing. Prices start from just €1,250 and the scope delivers functionality previously only available in substantially higher priced oscilloscopes, the company claims.
The R&S explained the background to this development, “For most of the past three decades, oscilloscopes have predominantly offered 8 bits of vertical resolution, which allows a signal to be mapped to one of 256 vertical positions.”
The R&S RTB2000 includes a proprietary 10-bit ADC with 1024 vertical positions and four times more resolution than other scopes in this segment. The increased resolution enables users to make more precise measurements and can be particularly useful for detecting small signals in the presence of large-amplitude signals.
After bandwidth and sample rate, memory depth is the most important attribute that determines an oscilloscope’s ability to handle a large range of troubleshooting tasks. The R&S RTB2000 oscilloscopes feature a 10 Msample acquisition memory on each channel, and 20 Msample per channel in interleaved mode. Furthermore, this large standard memory can optionally be further extended to 160 Msample.
The RTB2000 series sports a 10.1-inch capacitive touchscreen: twice the display size and up to ten times the number of pixels of comparable oscilloscopes in this segment.
Capacitive touch is becoming more important for oscilloscope users as it allows them to operate the instrument more quickly and efficiently. Plus, touch operation has become commonplace in the work and personal environment. With the R&S RTB2000, users with lower budgets will have access to not only touchscreen, but capacitive touchscreen operation with a large display.
These oscilloscopes come in two- and four-channel models and offer bandwidths of 70 MHz, 100 MHz, 200 MHz and 300 MHz. A number of upgrade options to extend the instrument’s capabilities are available, including 16 integrated digital channels with a mixed-signal oscilloscope option, protocol decode and triggering options for a variety of industry standard buses, as well as an arbitrary function generator and a 4-bit pattern generator.
