APPLICATION NOTELow-Cost Power Sources Meet ADC andVCO Characterization RequirementsKeysight B2961A/B2962A 6.5 Digit Low Noise Power SourceIntroductionFinding a cost-effective power source for precision measurement applications can be achallenging task.Analog-to-digital(ADC)converter circuits often require power sourceswith at least 20 bits of resolution.Voltage controlled oscillator (VCO)applications canrequire noise floors of 10 uV rms or less.While there are existing instruments andmeasurement techniques that can perform these measurements,the cost of the solutionscan often run into tens of thousands of dollars.In addition,many low-frequency(10 kHzor less)applications often need voltages and currents greater than typical signalgenerators can source.Finally,it can be very cumbersome to use a PC to controlinstruments in a benchtop lab environment,so a self-contained solution with a smallprofile,interactive GUl and built-in graphing capability is highly desirable.KEYSIGHT B2962A Power Seuree6.5digit 2ch L1230t:%9入6Cv+210.0000W+12.000nmt+105.0000mA9+210.00YCItEAWHcc+3,030000Ah41.2000+06.00000+3,0300Aot.KEYSIGHTTECHNOLOGIESFind us at www.keysight.comPage 1
