The 4040B generates sine, square, and triangle waveforms at up to 20 MHz, and provides variable output voltages from 0 to 10 Vp-p into 50 Ω or up to 20 Vp-p into open circuit. A continuously variable DC offset allows the output to be injected directly into circuits at the correct bias level.\u003c\/p\u003e\n\n\n\n\u003cp\u003eThe 4040B can be programmed remotely via the USB (virtual COM) interface using SCPI commands. Additionally, application software is available from B\u0026amp;K Precision that provides virtual front panel emulation, allowing users to remotely control their instrument without the need for programming.\u003c\/p\u003e\n\n\n\n\u003cp\u003e\u003cb\u003eIncluded:\u003c\/b\u003e Instruction manual on CD, power cord, USB (type A to B) interface cable, and certificate of calibration.\u003c\/p\u003e","brand":"B\u0026K Precision","offers":[{"title":"Default Title","offer_id":58410194010444,"sku":"21297.1","price":502.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/2245\/6652\/files\/4040B-750.jpg?v=1786719809","url":"https:\/\/www.testequity.co.uk\/products\/bk-precision-4040b-dds-function-generator-4040b","provider":"TestEquity UK","version":"1.0","type":"link"}
