Single-sideband phase noise typically \u0026lt; −122 dBc\/Hz at 1 GHz \/ 20 kHz offset, amplitude accuracy ≤0.7 dB (Typ.), and frequency switching ≤40 ms make it suitable for both bench R\u0026amp;D and automated test workflows.

Optional pulse and narrow-pulse modulation extends the instrument into pulsed RF test for radar component validation and time-gated stimulus work, with a minimum pulse width of 20 ns and 10 ns resolution.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-container\"\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cdiv class=\"product-key-features\"\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e9 kHz to 4.5 GHz Frequency Range\u003c\/strong\u003e — 0.001 Hz resolution and 0.1° phase offset step across the full band.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e−135 dBm to +25 dBm Level Range\u003c\/strong\u003e — 160 dB output range with 0.01 dB resolution and ≤0.7 dB amplitude accuracy typical.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase Noise \u0026lt; −122 dBc\/Hz at 1 GHz\u003c\/strong\u003e — single-sideband phase noise typical at 20 kHz offset, suited to sensitive receiver and component test.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMechanical Step Attenuator Standard\u003c\/strong\u003e — 0 to 110 dB range with 10 dB steps; mechanical attenuator delivers maximum absolute output power across all bands.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAM, FM, and ΦM Analog Modulation\u003c\/strong\u003e — internal, external, or internal + external modulation sources from the built-in 50 MHz AWG or rear-panel input.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStep and List Sweep\u003c\/strong\u003e — frequency and amplitude sweeps with 2 to 65,535 step points or 1 to 500 list points; LAN\/USB\/GPIB triggering.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e≤40 ms Frequency Switching\u003c\/strong\u003e — SCPI, list, and step-sweep switching speed for fast automated test cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in 50 MHz Function\/Arbitrary Waveform Generator\u003c\/strong\u003e — standard waveforms, sweep, and modulation from a second LF output on the front panel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Stability Internal Clock Source\u003c\/strong\u003e — ≤±0.2 ppm\/year aging, ≤±10 ppb temperature effects; calibration-cycle-friendly stability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10 MHz Reference Input\/Output\u003c\/strong\u003e — rear-panel BNC for multi-instrument synchronization.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e5-Inch Touch Screen with Signal-Flow Interface\u003c\/strong\u003e — full touch control over every function except the power switch.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLAN, USB Host, USB Device Standard; GPIB Optional\u003c\/strong\u003e — full SCPI automation from LabVIEW, Python, MATLAB, or Excel batch scripts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Control + Device Manager\u003c\/strong\u003e — browser-based remote access (PC and mobile) plus free PC management software (V2.5.0+).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptional Pulse Modulation\u003c\/strong\u003e — 80 dB on-off ratio with customizable pulse trains.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptional Narrow-Pulse Generator\u003c\/strong\u003e — 20 ns minimum width with 10 ns resolution for radar component test.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptional USB Power Sensor Support (USG3000-PK)\u003c\/strong\u003e — license-activated readback and flatness correction with a user-supplied USB power sensor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCE | cETLus | RoHS Compliant\u003c\/strong\u003e — meets common North American and European safety and environmental standards.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-container\"\u003e\n\u003ch2\u003eDetailed Features\u003c\/h2\u003e\n\u003cdiv class=\"product-row\"\u003e\n\u003cdiv class=\"product-box product-left\"\u003e\n\u003ch3\u003eHigh Spectral Purity for Sensitive Receiver and Component Test\u003c\/h3\u003e\n\u003cp\u003eSingle-sideband phase noise typically below −122 dBc\/Hz at 1 GHz with a 20 kHz offset is the headline spectral-purity figure that determines whether a generator can stimulate the device under test without contaminating the measurement.

the non-−P variant substitutes an electronic step attenuator. Both provide 0–110 dB range with 10 dB steps. Mechanical attenuators deliver higher absolute output power (~+4 dB above electronic at the 250 MHz–3.6 GHz bands); electronic attenuators switch faster and have longer service life. Choose mechanical for maximum output headroom, electronic for high-cycle automation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-faq-item\"\u003e\n\u003cp class=\"product-faq-question\"\u003eWhat automation interfaces are standard?\u003c\/p\u003e\n\u003cp\u003eLAN, USB Host, and USB Device are standard rear-panel interfaces. GPIB is optional. All ports support the standard SCPI command set, so the instrument drops into any existing automated test station (LabVIEW, Python, MATLAB, Excel) without protocol translation. Web Control provides browser-based remote access via the instrument's IP address — no client install required, works from PC and mobile. UNI-T's free Device Manager PC software (V2.5.0 and higher) handles batch instrument inventories via LAN (VXI-11, Socket), USB Device (USB-TMC), or GPIB.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product-faq-item\"\u003e\n\u003cp class=\"product-faq-question\"\u003eWhat does the USG3000-PK power sensor option provide?\u003c\/p\u003e\n\u003cp\u003eUSG3000-PK is a software license that activates USB power sensor support in the instrument. The user connects a compatible USB-TMC power sensor (sold separately) to the front-panel USB Host port; the instrument displays the power measurement on its own screen with menu controls for measurement frequency, frequency coupling (multiplier + offset), amplitude offset for path-loss compensation, and averaging. The primary use case is flatness correction and cable-loss compensation at the DUT plane — the amplitude offset entry compensates for cables and adapters between the generator and the device under test. License is activated via UNI-T's standard option-install workflow.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003c\/div\u003e","brand":"UNI-T","offers":[{"title":"Default Title","offer_id":51324537209116,"sku":"181300200014X","price":13199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0822\/9208\/0924\/files\/USG3000_F-S.png?v=1740667739","url":"https:\/\/uni-trendus.com\/products\/usg3045m-p","provider":"Uni-Trend US","version":"1.0","type":"link"}
