The Anritsu MG3690B Series RF/Microwave Signal Generators are synthesized signal sources covering frequencies from 0.1 Hz to 67 GHz across six base models, with optional waveguide extension to 110 GHz at millimeter-wave frequencies. The series is offered as a family of basic CW generators that are fully configurable and upgradeable to full-featured signal generators with comprehensive modulation capabilities. The MG3690B leverages the proven design of earlier Anritsu synthesizers, building on a reliability record exceeding 49,000 hours MTBF, and is packaged in a 13.3 cm (3U) chassis with 45 cm depth — a low-profile, rack-friendly footprint engineered for automated test environments.

Per the datasheet, the MG3690B is positioned for signal simulation applications including Automatic Test Equipment (ATE), Bit Error Rate Testing (BERT) where it serves as a clock source, Scalar Network Analyzer (SNA) measurements, mixer measurements using Master/Slave configurations with two tracking synthesizers, and TWTA measurements via external power meter leveling mode. The high-performance signal generator variants are described as suited to electronic warfare (EW) signal simulation, with synchronized Pulse with AM/FM/ΦM capability and pulse generator with swept delay for moving target simulation including singlet, doublet, triplet, and quadruplet pulses.

ValueTronics International, LLC has stocked, tested, and shipped Anritsu RF and microwave signal sources from its 20,000-square-foot secure warehouse at 1675 Cambridge Drive, Elgin, Illinois since 1992. Every MG3690B-family instrument that ships through our facility is inventoried, condition-graded, and verified by our in-house technical team before it leaves the dock, with calibration upgrade paths available to match the documentation requirements of the buyer's quality system. The Elgin location is operated directly by ValueTronics — not a drop-ship or pass-through arrangement — so the unit you order is the unit we have hands on.

Brand Heritage

Anritsu Corporation is a Japanese precision measurement company with roots in test and measurement dating to the late 19th century. The MG3690B microwave signal generator line carries forward the Wiltron heritage in U.S. microwave instrumentation: Wiltron Company, a long-established American microwave test equipment maker, was acquired by Anritsu in 1990, and the resulting combined organization consolidated microwave signal generation development under the Anritsu brand. The MG3690B explicitly builds on the proven design of earlier Anritsu (and Wiltron-lineage) synthesizers.

Compare Other Models in This Series

The MG3690B Series is offered as six base models that differ primarily by upper frequency limit, with each model sharing the same chassis, the same modulation option set, the same control interface, and the same DDS-plus-DDC-plus-PLL synthesis architecture described in the datasheet. Per Anritsu's positioning, the series is built as a fully configurable platform: a basic CW generator at the entry frequency tier can be ordered with the same option suite as the top-tier model, and any unit can be field-upgraded with additional options as test requirements evolve.

Because the chassis, front panel, GPIB interface, and software driver set are common across the series, an ATE program built around any MG3690B model migrates to a higher-frequency variant without requiring new instrument drivers or code changes. The 13.3 cm (3U) height and 45 cm depth are identical across the six models, simplifying rack planning when the frequency tier is selected based on the highest signal frequency the test program needs to generate.

Each pre-owned MG3690B-series model listed below has its own dedicated product page with condition-matched pricing. Specifications, modulation options, and rear-panel I/O remain identical between the new-distribution and pre-owned listings for the same model and option string — the model decision is driven by the upper frequency required for the application, and the condition decision is driven by the buyer's procurement and budget framework.

The six models differ in their upper frequency limit: MG3691B reaches 10 GHz, MG3692B reaches 20 GHz, MG3693B reaches 30 GHz, MG3694B reaches 40 GHz, MG3695B reaches 50 GHz, and MG3696B reaches 65 GHz with operational extension to 67 GHz. The lower end of the standard band starts at 2 GHz across all six models, with 10 MHz coverage available via Option 5 (standard phase noise) or Option 4 (ultra-low phase noise) and 0.1 Hz to 10 MHz audio coverage available via Option 22 on any base model.

Output power varies with frequency tier when the High Power option (15X) is installed: +25 dBm to 10 GHz, +23 dBm to 20 GHz, +19 dBm to 40 GHz, +13 dBm to 50 GHz, and +3 dBm to 65 GHz. Standard output power is +17 dBm at 20 GHz. The comparison table below summarizes the headline frequency tiers and primary differentiators across the six base models — see the per-model spec tables for the full performance picture at each frequency point.
