DESCRIPTION:
The Rohde & Schwarz RTA4004 is the highest bandwidth four-channel model within the RTA4000 Series, delivering 500 MHz analogue bandwidth and incorporating Rohde & Schwarz's high-performance 10-bit ADC architecture. The instrument is designed for engineers requiring advanced debugging capability, deep acquisition memory, mixed-signal expansion, and comprehensive analysis tools within a compact laboratory platform.
The RTA4000 family utilizes a custom 10-bit analog-to-digital converter that provides four times the vertical resolution of conventional 8-bit oscilloscopes. This increased resolution enables more accurate visualization of low-level signal details, switching ripple, transient disturbances, power integrity issues, and signal integrity problems encountered in modern electronic systems.
The RTA4004 supports real-time sampling rates up to 5 GSa/s and provides up to 100 Mpoints acquisition memory. The combination of deep memory and high sample rates allows engineers to capture long-duration events while maintaining fine timing resolution. This makes the instrument particularly effective for serial communications analysis, embedded systems debugging, industrial automation troubleshooting, motor drive analysis, and power electronics development.
A major strength of the RTA4000 platform is its integrated analysis capability. Standard functions include FFT spectrum analysis, waveform mathematics, mask testing, automatic measurements, advanced triggering, history mode, and search functions. Optional software packages expand capability with serial bus triggering and decoding, power analysis, frequency response analysis, and advanced protocol analysis.
The platform is also MSO-ready and can be upgraded with 16 digital logic channels, enabling simultaneous analogue and digital analysis. Protocol support includes I2C, SPI, UART, CAN, LIN, RS-232, RS-422, RS-485, I2S, ARINC 429, and MIL-STD-1553, making the instrument suitable for complex embedded and communications applications.
The large 10.1-inch WXGA capacitive touchscreen provides ample display space for viewing multiple waveforms, protocol decodes, FFT measurements, and automated analysis results simultaneously. Combined with fast acquisition rates and deep memory architecture, the RTA4004 serves as a powerful platform for modern electronics development and troubleshooting.
