Frequency Isolator / Divider Board
Add the Frequency Isolator / Divider Board to an ATE System fixture and program and measure up to eight electronic oscillator frequencies to 100MHz during In-Circuit Test
The TestNet Frequency Isolator / Divider Board is used for dealing with the measurement of high frequency oscillators and generators.
High frequency oscillators and generators are difficult to test using normal ICT test methods. With the need to improve pin fault coverage and reduce process faults, the test should be not only for existence, but for functionally and accuracy. Using the Frequency Isolator / Divider Board provides a simple and effective way for testing multiple clock signals on your circuit assembly. The Frequency Isolator/Divider Board accommodates the testing of up to eight (8) clock signals.
The board uses relays to isolate the clock signals form the test system and other clock lines. Mounting the Frequency Isolator / Divider Board as close as possible to the DUT reduces the loading effects from the fixture wires and test system while reducing cross talk. The high frequency signal is isolated and sent into a circuit that divides the frequency down to a level the test system can reliably measure. The division factors are 2, 4, 8, 16, 32, 64, 128, or 256.
Now, high frequency oscillators and generators on printed circuit boards can be reliably measured thus verifying their presence and functionality. The production process no longer has to rely on visual inspection to detect these components that may be missing or wrong or that have poor solder connections.
Oscillator and Generator testing, all become more reliable when incorporating this board into the ATE test fixture and as part of the test program. The board helps ATE engineers provide more complete and stable test programs in less time. The net effect is significant cost savings due to shortened test development time, improved process test coverage, and then improved yield at functional test.
The board mounts inside the test fixtures for ATE systems from suppliers including Teradyne, Agilent, GenRad, and others.
The list price of the Frequency Isolator / Divider Board is under $360 and less in quantities.
