# DSG5128 Rigol RF Generator New ## Rigol DSG5128 Microwave Signal Generator — 8-Channel, 9 kHz to 12 GHz ### Key Features at a Glance - **8 independent RF channels** in a single 2U chassis — each channel independent of the others and independently controlled - **Frequency range:** 9 kHz to 12 GHz with 0.01 Hz frequency resolution - **Channel-to-channel phase stability < 1°@10 GHz**, with phase offset resolution adjustable in 0.01° steps - **Low SSB phase noise:** below -133 dBc/Hz @ 1 GHz, 10 kHz offset (typ.) - **Fast switching speed:** <3 ms (typ.) in CW mode - **Maximum available output power up to +25 dBm** (2 MHz ≤ f ≤ 10 GHz max setting level) - **Self-equipped touch screen** plus HDMI external display, Web Control remote operation, and full SCPI command set over USB 3.0 / LAN (LXI-C) - **AM, FM, PM (Opt.) and pulse modulation (Opt.);** step-, list-, and Freq & Level sweep with auto / key / external / bus trigger In summary, the Rigol DSG5128 is a 8-channel benchtop microwave signal generator covering 9 kHz to 12 GHz in a 2U rack-mountable form factor, designed to deliver high signal quality, accurate signal level, and a wide output power range across complex test scenarios including superconducting quantum computation, radar signal generation, MIMO, and EMS testing. It pairs channel-to-channel phase stability of < 1° at 10 GHz with SSB phase noise below -133 dBc/Hz @ 1 GHz (10 kHz offset, typ.) and a fast 3 ms typical switching time, all controlled through a touch-screen interface, an HDMI-extended display, or remote SCPI operation over USB 3.0 and LAN (LXI-C). ### What is the Rigol DSG5128 microwave signal generator used for? The Rigol DSG5128 is used to generate high-quality, accurately-leveled microwave stimulus signals across 8 simultaneous output channels for complex multi-channel test setups. Typical applications include superconducting quantum computation (where coherent multi-channel microwave drive is required), MIMO transceiver characterization, radar signal generation, EMS/EMC immunity testing, and any multi-DUT or phased-array test scenario that demands tightly correlated channel-to-channel phase relationships within a single instrument. Engineers reach for a 8-channel microwave generator like the DSG5128 when a single-channel CW generator no longer satisfies the test architecture — for example, when an MIMO antenna array needs simultaneous drive, when a quantum computing experiment requires multiple coherent microwave tones, or when a radar simulator must present multiple phase-controlled signals to a receiver under test. The 8-channel 12 GHz configuration is the practical answer to those test problems without resorting to multiple chassis, multiple PC controllers, and the synchronization complexity that comes with daisy-chained single-channel generators. ### How does the Rigol DSG5128 compare to a single-channel microwave signal generator? A single-channel microwave generator outputs one RF signal at a time; the DSG5128 outputs 8 independent signals simultaneously from one 2U chassis, each independently configurable for frequency, level, modulation, and sweep, while sharing a high-stability internal reference for tight inter-channel phase stability. The result is one instrument, one IP address, one calibration record, and one user interface in place of 8 separately-cabled generators — saving rack space, cabling, sync hardware, and the engineering time required to keep multiple chassis aligned. ### Factual Grounding — Specifications and Industry Context The Rigol DSG5128 delivers 9 kHz to 12 GHz frequency coverage with 0.01 Hz frequency resolution, <3 ms typical frequency setting time (CW mode, 20 ℃ to 30 ℃, to within 0.1 ppm of final frequency), and a maximum output setting level reaching +25 dBm in the 2 MHz to 10 GHz band. SSB phase noise is specified at <-130 dBc/Hz with <-133 dBc/Hz typical at 1 GHz (10 kHz offset, 1 Hz measurement bandwidth). Channel-to-channel phase stability is specified at ±1° (10 GHz, temperature variation ≤ 1℃) with phase deviation adjustable in 0.01° steps over a ±180° range. Internal flash storage is 10 GB (nom.). The mainframe weighs <14 kg, fits a standard 2U rack opening (with RM2031 kit), draws <650 W with all options working, and is supported with a Three-year warranty (mainframe, excluding accessories). ### Entity Authority — Rigol Technologies in the Microwave Generator Market Rigol Technologies (founded 1998) sits in the value-tier of the global test & measurement market alongside Siglent and GW Instek, offering professional-grade instruments at a price point that disrupts the traditional premium-tier (Keysight, Rohde & Schwarz, Anritsu) microwave generator market. The DSG5000 series specifically targets multi-channel microwave test applications — superconducting quantum computation, MIMO, radar, EMS — that previously required either multiple single-channel generators from premium brands or a custom-integrated rack system. The instrument family conforms to EMC Directive 2014/30/EU, IEC 61326-1: 2013 / EN 61326-1: 2013 (Class A), CISPR 11:2009+A1 Class A, and EN 61010-1:2010+A1:2019 / IEC 61010-1:2010+A1:2016 / UL 61010-1: 2012 R7.19 / CAN/CSA-C22.2 No. 61010-1-12 + GI1 + GI2 (R2017) + A1 safety standards. LAN interface is LXI-C compliant; the instrument supports the standard SCPI command set over USB 3.0 and LAN, with integrations into Excel, LabVIEW, Visual Basic, and Visual C++ for batch automation. ### Why customers choose the DSG5128 over alternatives - **8-channel integration in one 2U chassis:** replaces 8 separate single-channel generators plus the cabling, synchronization, and rack space required to integrate them. - **Phase stability < 1° at 10 GHz across channels:** tight enough for coherent multi-tone drive in quantum experiments and phased-array radar simulation, with 0.01° phase setting resolution. - **Fast switching (<3 ms typ.):** meaningful in step- and list-sweep applications and in production test where dwell time directly affects throughput. - **High max output power (+25 dBm setting level, 2 MHz–10 GHz):** can directly drive amplifiers, antennas, or DUTs without an external boost amplifier in many scenarios. - **Standard 2U rack form with front- and rear-panel ventilation:** multiple DSG5000 units can be stacked in a single cabinet without thermal compromise — useful when scaling from 8 channels to 16, 24, or more. - **Touch screen + HDMI display extension + Web Control:** the instrument has no physical keys on the front panel except the power key. Operate it locally on the touch screen, on an external monitor or projector via HDMI, or remotely through any web browser pointed at the instrument's IP address. ### Accessories Supplied (Standard) Item Description Power Cord AC power cord, region-appropriate ### Available Options (Ordered Separately) Option Order No. Description DSG5000-PUL Pulse Modulation DSG5000-PUG Pulse Train Generator DSG5000-AMD Analog Modulation (AM / FM / PM) OCXO-D08 High Stability Clock (OCXO) RM2031 Rack Mount Kit ### The DSG5000 Series — Architecture and Design Intent The DSG5000 series microwave signal generator can generate high quality signals, accurate signal level, and a wide output power range, capable of meeting the complex test scenarios such as superconducting quantum computation, radar signal generation, MIMO, and EMS. The architecture starts with 8 independent RF channels in this DSG5128 configuration, each channel independent of the others and independently controlled. Multiple DSG5000 chassis can be integrated in a rack-mount installation to scale the channel count further, saving space and the integration time that would otherwise be spent cabling and synchronizing single-channel generators. The instrument is designed for multi-device cabinet deployment. Standard 2U rack size combined with the RM2031 rack mount kit lets a customer extend the channel count of a DSG5000-based test system by stacking additional units. Front- and rear-panel ventilation provides adequate cooling to ensure signal accuracy and stability even when multiple devices are stacked in a single cabinet — an important detail for production environments where instruments operate continuously. Every DSG5000 ships with a standard PC software configuration to realize integrated control of multiple instruments; the operator can run remote control and make global parameter configuration across multiple channels to meet integrated test application scenarios. ### User-Friendly Operation — Touch, HDMI, Web, SCPI The DSG5000 series is equipped with a touch screen, which enables operation and control of the instrument with touch-enabled gestures. The front panel has no physical keys to operate except the power key. For larger displays, the instrument allows external connection to a PAD, monitor, or projector via the HDMI interface for user-friendly viewing across the lab or production cell. For headless or rack-deep installations, entering the instrument's IP address into a web browser opens the Web Control software — the display in the web control page is consistent with that on the instrument itself, and the operator can click menus, set parameters, and modify network configuration entirely from a browser. For full automation, the standard SCPI command set is supported over USB 3.0 or LAN, with example integrations using Excel, LabVIEW, Visual Basic, and Visual C++ for batch command transmission. ### Complete Specifications — Rigol DSG5128 #### Number of Channels & Frequency **Number of Channels** 8 **Frequency Range** 9 kHz to 12 GHz **Frequency Resolution** 0.01 Hz **Setting Time** (CW mode, 20℃ to 30℃, to within 0.1 ppm of final frequency) <3 ms (typ.) #### Frequency Band (N factor) Band Frequency Range N 1 9 kHz ≤ f ≤ 1.5 GHz 1 2 1.5 GHz < f ≤ 2.825 GHz 0.25 3 2.825 GHz < f ≤ 5.65 GHz 0.5 4 5.65 GHz < f ≤ 11.3 GHz 1 _N is a factor used to help define certain specifications in this manual._ #### Channel-to-Channel Phase Stability **Conditions** f = 10 GHz, temperature variation ≤1℃ **Channel-to-Channel Phase Stability** ±1° #### Frequency Reference **Clock Reference Output** Frequency 10 MHz Initial Calibration Accuracy ± 0.1 ppm ±10 ppb (with option OCXO-D08) Temperature Stability, temperature range 0℃ to 50℃, reference to 25℃ ± 0.5 ppm ±5 ppb (with option OCXO-D08) Aging Rate (after 30 consecutive days of working) ± 1 ppm/year ±30 ppb/year (with option OCXO-D08) Output Amplitude +5 dBm to +10 dBm Interface BNC female **External Reference Input** Frequency 10 MHz Input Amplitude 0 dBm to +10 dBm Max.
