Huntron HSR410

The Huntron HSR410 is a switching interface that bridges circuit boards under test with Huntron Trackers to enable IC-level component troubleshooting. By routing signals from both a board under test and a known good reference board through the switcher to the tracker, the HSR410 facilitates rapid comparative analysis without requiring pin-by-pin evaluation. The device features a variable rate controller to adjust comparison switching speed displayed on the Tracker’s CRT, making it ideal for in-circuit and out-of-circuit IC diagnostics. It also integrates with general-purpose test equipment for power-on troubleshooting applications.
