Question What options are available to make use of my existing inventory of uniaxial piezoelectric accelerometers when a triaxial measurement is required at a single location? Previously I have not had requirements to make triaxial measurements at a single point, but now I am seeing more and more requirements based on new testing parameters. Are […]

Question We are replacing our differential accelerometers with 7703A’s that have single-ended outputs. We are also using 2777A differential charge amplifiers. Can I use the 2777A with the 7703A, or do I have to replace the charge amplifiers? Answer Yes. You can make the differential input into a single-ended input by connecting Pin B, of […]
