New embedded oscilloscope family

18th January 2018

Rohde & Schwarz is expanding its oscilloscope portfolio with the R&S RTM3000 and R&S RTA4000 series. The 10-bit vertical resolution enables power measurements fulfilling the more stringent requirements demanded by advanced electronics. The R&S RTA4000, which is also ideal for analysing serial protocols, even offers an acquisition memory depth up to 1 Gsample.

The new R&S RTM3000 oscilloscope offers bandwidths of 100 MHz, 200 MHz, 350 MHz, 500 MHz and 1 GHz. The products incorporate a proprietary 5 Gsample/s 10-bit ADC, and each model includes 40 Msample (80 Msample interleaved) per channel acquisition memory with an optional 400 Msample segmented acquisition memory. The new R&S RTA4000 oscilloscope offers bandwidths of 200 MHz, 350 MHz, 500 MHz and 1 GHz.

These models include the same 10-bit ADC, but have even more memory, with 100 Msample (200 Msample interleaved) per channel acquisition memory and standard 1 Gsample (1,000 Msample) segmented acquisition memory. Both instrument series feature a 10.1" capacitive touchscreen display to operate quickly and efficiently.

Power measurements, such as ripple and noise measurements of a DC line, demand an oscilloscope with high vertical resolution, low noise and
excellent DC gain linearity. For most of the last 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 10-bit ADCs of the R&S RTM3000 and R&S RTA4000 series support 1024 vertical positions. This is four times better than the common 8-bit oscilloscopes in this segment and essential for ripple and noise measurements. Both oscilloscope series provide extremely low signal noise, while the R&S RTA4000 series also offers class-leading signal integrity characteristics such as a DC gain accuracy down to 1%.
