I have some questions for those of you out there using TDS-220 scopes. What is the one shot sample rate like? And at what memory length? What is the width of the A/D sample and hold aperture? I use Fluke 99 scopemeters around here for a lot of work and although basically good for a lot of measurements, they give me fits sometimes because of resolution, aliasing, and aperture width limitations. -Frank Frank Richterkessing Experimental Methods Engineer GE Appliances FRANK.RICHTERKESSING@APPL.GE.COM
