DETAILED FEATURES
 
Live In-Rack Testing: Run and align your 500-series modules in real time using the power and audio connections directly from your 500-series chassis
1 Meter Cable Flexibility: The generous 100 cm cable length allows convenient placement of the test board on your workbench next to the rack
Direct Rail Voltage Monitoring: Dedicated 4 mm Hirschmann test points provide fast, accurate checking of +16 V, -16 V, and +48 V rails with standard multimeter leads
Flexible Power Options: Operate the module directly from the host rack, connect a bench supply via banana jacks, or use an external 5-pin VPR power supply
Multi-Board Expansion: Built-in 5-pin Phoenix terminal strip allows interconnecting additional extension boards for expanded test setups
