Rohde & Schwarz Announced a New Embedded Oscilloscope Family
16 January, 2018
R&S RTM3000 and R&S RTA4000 series come with 10-bit vertical resolution enables power measurements fulfilling the more stringent requirements demanded by advanced electronics. The R&S RTA4000 offers an acquisition memory depth up to 1 Gsample.
Rohde & Schwarz is expanding its oscilloscope portfolio with the R&S RTM3000 and R&S RTA4000 series. Their 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 analyzing 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 an astonishing 100 Msample (200 Msample interleaved) per channel acquisition memory and standard 1 Gsample (1,000 Msample) segmented acquisition memory. Both instrument series feature a brilliant 10.1″ capacitive touchscreen display to operate quickly and efficiently.
10-bit vertical resolution
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 %.
Memory Depth for Serial Protocol Analysis
After bandwidth and sample rate, memory depth is the most important attribute that determines the instrument’s ability to handle a large range of troubleshooting tasks. Additional acquisition memory gives users longer time captures for testing and troubleshooting. This is especially true when analyzing serial communications or power on and off sequences. The R&S RTM3000 series oscilloscopes have eight to 20 times more memory than leading instruments from other manufacturers in this class. With 1 Gsample segmented memory, the R&S RTA4000 series has 200 times more memory than other oscilloscopes in its class that offer segmented memory.
