Backplane/Chassis Test Solutions W 3525

The W 3504 and W 3525 Test Systems are perfectly designed to test from medium-sized to really huge backplanes and racks. They manage the testing of a huge number of connections within a really short time period—with up to 300,000 test points.The integration of test points into mobile daisy-chain cartridges avoids complicated and error-prone adaption and shows a higher accuracy. It also enables a faster, automatable contacting and leads to a higher throughput.
Test & Measurement Performance
Maximum Voltage of 250 VDC (12-Bit Resolution)
Constant Current of 1 mA, 10 mA, or 50 mA
Continuity Thresholds down to 0.5 Ohms (± 2% ± 0.25 Ohms)
Insulation Threshold up to 10 MOhm (± 1%), up to 100 MOhms (± 3%)
Resistor Test from 0.5 Ohms to 100 MOhms (± 3% ± 0.25 Ohms)
Capacitor Test from 20 nF to 40,000 µF (± 10% ± 10 nF)
Diode and Zener Diode Test for Open, Short and Reversed Insertion
Function Test of Keys and Switches

Hardware
Daisy Chain Cassettes Populated with Plug-In Transistor Test Point Modules as Required for the Pin Count of the Target Connector
External Modules with 32, 128, 192 or 256 Test Points
PCI Interface for Connection to a PC (Includes Interface Cable)
Expandable to 307,200 Test Points
Optional Remote Control Interface for Driving Peripheral Devices (Fixtures, 
Feeders, etc.)

Dimensions & Weight
19-inch Rack-Mount Enclosure on Wheels
21.7 x 19.7 x 23.6 inches (W x D x H)
110 lbs

Highlights
• Fast test speed and at the same time optimized accuracy
• Highly variable during configuration of the test system
• Ideal customization to an existing manufacturing system

Fast test speed and a the same time optimized accuracy
• Quick test times through single transistors (single point switching matrix)
• Highly accurate through minimization of adaption cables and the number of plug connectors between test points and the unit under test (UUT)

Ideal customization to an existing manufacturing system, including automatable contacting
• Customizable configuration of the daisy-chain cartridges with regards to the number of contacts and the mating plugs
• Minimum number of connection cables, since one daisy-chain cable links the tester with the first cartridge and from there only one daisy-chain cable links one cartridge with another one
