It is positioned as more than a waveform viewer: the platform combines oscilloscope measurements with a logic analyzer, protocol analyzer, spectrum analyzer, a waveform and pattern generator and a digital voltmeter, all reachable through a large, high-resolution capacitive touchscreen with the R&S SmartGrid user interface. An oscilloscope captures voltage waveforms over time and displays them on a screen, letting an engineer see a signal's amplitude, frequency, timing and shape. For the R&S RTA4004, the applications called out include everyday debugging and troubleshooting, characterization of switched-mode power supplies where the voltage across the switching device must be resolved during on/off times, EMI debugging, power integrity work such as measuring ripple and periodic and random disturbances (PARD), power analysis, and efficient debugging of serial buses in embedded designs. ValueTronics stocks and holds its own inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, which keeps fulfillment and condition control in our own hands. ## Brand Heritage Rohde & Schwarz is an independent, family-owned company headquartered in Munich, Germany, founded more than 80 years ago. It has operated under the Rohde & Schwarz name without a major corporate renaming or acquisition. ## Accessories Supplied - One R&S®RT-ZP10 500 MHz passive probe per channel - Power cord ## Product Core & Specifications Specification Value Vertical system Input channels (R&S®RTA4004) 4 channels Input impedance 50 Ω ± 1.5 % (meas.); 1 MΩ ± 1 % || 14 pF ± 1 pF (meas.)
