# Rohde & Schwarz SMR60 60 GHz Microwave Signal Generator (Pre-Owned) # Rohde & Schwarz SMR60 60 GHz Microwave Signal Generator (Pre-Owned) ## Key Features At A Glance - Frequency coverage from 10 MHz up to 50 GHz (SMR50) or 60 GHz (SMR60) across the series - CW generator with pulse modulation and digital frequency sweep standard on every unit - Standard pulse modulator: on/off ratio better than 80 dB, rise/fall time under 12 ns - Field-upgradeable to AM/FM signal generator (option SMR-B5) or analog ramp sweep generator (option SMR-B4) - Optional internal pulse generator (option SMR-B14) for radar and EMC applications - IEC/IEEE-bus (IEEE 488) remote control with SCPI command set for automated test systems - Storage for 50 complete instrument setups; one-hand EasyWheel operation with online help - 3-year calibration cycle; compact and lightweight at under 13.5 kg fully equipped The Rohde & Schwarz SMR50 and SMR60 are microwave signal generators that extend the SMR family with two models reaching up to 50 GHz and 60 GHz respectively. Each is a CW generator with pulse modulation capability, positioned as a high-performance, cost-effective, and reliable microwave source. The standard lower frequency limit is 1 GHz, which can be extended down to 10 MHz with the Frequency Extension option (SMR-B11). A microwave signal generator produces a known, controllable carrier used to stimulate and characterize a device under test. The SMR50/60 are suited for use as a source for optical components, a source for radar receiver tests, a source for scalar network analysis, and a normal CW source for local-oscillator substitution. Microwave signal generators of this kind are frequently used for calibrating test receivers, a task that calls for a highly accurate and stable output level. The combination of pulse and frequency modulation (FMDC) simulates Doppler effects and chirp signals, while combined SCAN and pulse modulation reproduces the signals occurring in pulse radar applications with a rotating antenna. Their pulse modulation capability also supports the development, production, and maintenance of radar equipment. ValueTronics stocks and holds its own inventory in a 20,000-square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every used unit is inspected and functionally verified in-house before it ships, while new units leave factory-sealed exactly as received from the manufacturer. ## Brand Heritage Rohde & Schwarz is a privately held company founded in 1933 in Munich, Germany, by Lothar Rohde and Hermann Schwarz. It has operated continuously under the same name and ownership structure, with no major corporate rebranding or acquisition history. ## Compare Other Models in This Series The Rohde & Schwarz SMR family is extended by two microwave signal generator models, the SMR50 and the SMR60. Both are CW generators with pulse modulation capability and a standard lower frequency limit of 1 GHz, differing principally in their upper frequency reach. Owing to their price/performance ratio, both are positioned for economical microwave test setups, and either can be upgraded over time into an AM/FM signal generator or a synthesized sweep generator through the same flexible options concept. Each model shares the same architecture: high-precision frequency-response-compensated level control, a standard pulse modulator, digital sweep, 50-setup memory, and SCPI remote control over the IEC/IEEE-bus. The choice between the two is driven mainly by the required top frequency and the corresponding guaranteed output level at that frequency. Each pre-owned model in the family is presented on its own dedicated product page with condition-matched pricing. Use the comparison below to identify the model whose frequency coverage and output level fit your application, then open that model's page for its full specifications and current pre-owned availability. The two models differ primarily in upper frequency limit: the SMR50 covers up to 50 GHz and the SMR60 up to 60 GHz, with both extendable down to 10 MHz via the Frequency Extension option (SMR-B11). This difference carries through to the guaranteed output level at the top of each model's range, where the SMR50's ceiling allows correspondingly higher output near 50 GHz than the SMR60 provides near 60 GHz. Beyond frequency tier, the models are configured identically and accept the same option set, including the OCXO reference, 0.1 Hz resolution, ramp sweep, AM/FM/SCAN modulator, pulse generator, and the RF attenuator that extends the level setting range to -110 dBm. The comparison table that follows lists the per-model frequency and level figures side by side.
