Add the operating profile, safety boundary, control interface and acceptance evidence expected by the buyer before requesting final configuration and lead time.
Quote workflow
A useful RFQ is a short engineering model: operating envelope, DUT workflow, control boundary and acceptance evidence.
Send RFQStart with -120 dBm to +17 dBm; -120 dBm to +17 dBm. Confirm the required model rating before treating the page summary as a released configuration.
Map the equipment to Semiconductor test and characterization; Quantum technology research; Radar system development and record any transient, cycling, compliance or automation needs.
Confirm USB 2.0 (4x), Ethernet, BNC pulse/trigger I/O, 10/100 MHz reference, protection requirements, data logging, remote control and the FAT/SAT evidence needed by the buyer.
This product page summarises YSG-400B Series Signal Generator within XGY Tek's Signal Generators catalogue. Review the published specifications and application notes to determine whether the product matches the intended workflow.
Start with the values highlighted on this page: Frequency Range: 9 kHz - 20 GHz / 40 GHz; Resolution: 0.001 Hz; Output Power: -120 dBm to +17 dBm; Operating Mode: CW / Sweep. Check whichever selection criteria apply, such as measurement or operating range, resolution, accuracy, sensitivity, interfaces, software compatibility, environmental limits, accessories, and any stated test conditions. Not every criterion applies to every product.
Published applications include Semiconductor test and characterization; Quantum technology research; Radar system development; Advanced communication applications; Professional test and measurement applications. Use the application notes as selection guidance, then confirm the required operating conditions, interfaces, software compatibility, and accessories against the published specifications.
Compare alternatives when the published measurement or operating range, resolution, accuracy, sensitivity, interfaces, software compatibility, environmental limits, or available accessories do not match the intended workflow. Confirm any critical value together with its stated conditions before selecting a configuration.
