It is offered with a frequency range of 9 kHz to 1.1 GHz or 9 kHz to 3.2 GHz depending on the installed RF path option, and is positioned as a flexible, universal all-purpose signal generator. It is described as the smallest signal generator in its economy class, occupying a ½ × 19", 2-height-unit form factor, and is lightweight for both bench and portable work. Rohde & Schwarz identifies the SMC100A as an ideal tool across several application fields: service and maintenance, research and education, field use, secure areas, and simple production applications. Its compact dimensions, integrated analog modulation, and straightforward operation suit these general-purpose stimulus tasks. ValueTronics holds and stocks its own test-and-measurement inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive, Elgin, Illinois. Used units are inspected and functionally verified in-house against the original manufacturer's specifications before they ship, while new units leave our facility factory-sealed exactly as received from the manufacturer. Handling inventory directly in our own warehouse lets our team stand behind every instrument we sell. ## Brand Heritage Rohde & Schwarz is an independent group of companies specializing in electronics, established more than 75 years ago with company headquarters in Munich, Germany. It has operated under the Rohde & Schwarz name throughout its history, with no major corporate name change or acquisition affecting the brand. ## Accessories Supplied - Power cable - Quick Start Guide - CD-ROM (with operating and service manual) ## Product Core & Specifications Specification Value Frequency Range (SMC-B101 option) 9 kHz to 1.1 GHz Range (SMC-B103 option) 9 kHz to 3.2 GHz Resolution of setting 0.001 Hz Resolution of synthesis (f = 1 GHz) 4.71 µHz (nom.)
