Arbitrary function generator introduction

If the simple DIY generator is not to your liking you might want to consider something  Function/Arbitrary Waveform Generator supplied in this case .
I won’t bore you with spec you can read online but the basic spec includes up to 20Mhz signal out, 14 bit precision, more stored waveforms than you can shake a stick at with the ability to store up to 20 arbitrary waveforms (hence the term Arbitrary Waveform Generator), two independent outputs, lightweight, decent display, external PC control, TTL output and a whole lot more. The 20MHz Function Generator gives you a good look around this device.

How To Facilitate The Observation Of Small Signals?

图片
How to set up the high sensitivity of the  Spectrum Analyzers  to facilitate the observation of small signals? A: first, set the corresponding center frequency sweep width (span) and reference level according to the size of the small signal under test;Then, the attenuation value is gradually reduced in the absence of any overload warning in the spectrum analyzer.If the SNR of the measured small signal is less than 15db, RBW will be gradually reduced. The smaller RBW is, the lower the base noise of the spectrum analyzer will be, and the higher the sensitivity will be. If the spectrum analyzer from  Spectrum Analyzer Supplier  has pre-amplifier, opening pre-amplifier and pre-release can improve the noise coefficient of the spectrum analyzer, thus improving the sensitivity. For small signals with low signal-to-noise ratio, it can reduce VBW or adopt trajectory average to smooth the noise and reduce fluctuation. It should be noted that the measurement result o...
