Silicon Investigations HP 3561A & 3562A Dynamic Signal Analyzer Repair Service


The HP 3562A Dynamic Signal Analyzer can accurately measure signals from 64 uHz to 100 Khz.  It includes the ability to make FFT frequency response measurements, perform spectrum analysis, and transient analysis.  The 3562A has a dynamic signal range of 140 dBm for each input.

S.I. also repairs the HP 3561A, which is a single channel version of the HP 3562A.

These analyzers were known for display failures, problems with the power supplies, and input board failures.  We usually have exchange spares in stock for most common problems.  These machines are still a good value for the dollar on the used market.  If you are looking to buy a refurbished machine, please contact us to check availability. We also purchase used machines.   Please contact us for information on repairing your machine.
