Abstract
Test fixture includes measurement terminals that connect to an oscillator to be tested and contacts that connect to a printed circuit board. The printed circuit board includes a load capacitance circuit with load capacitance contacts and a direct coupling circuit with direct coupling circuit contacts. By changing the direction or orientation of the printed circuit board or reversing its top or bottom surfaces when attaching it to the test fixture, it is possible to switch between a configuration that connects a load capacitance to the oscillator and that directly couples the oscillator to a measurement system.
Claims7
Test fixture for measuring properties of a circuit element comprising:
- element connection means for connecting said circuit element to be tested;
- and
- board connection means for connecting a circuit on a circuit board to said circuit element;
- wherein said circuit element and said circuit board can be attached or removed from said test fixture independently of each other, said circuit board containing multiple independent circuits having contact points for connecting to said board connection means, each of said multiple independent circuits being individually connectable to said board connection means and said circuit element to be tested, based on an orientation of said circuit board.
Test fixture apparatus, comprising:
- test circuitry for generating test signals;
- a device to be tested;
- connector means including plural contacts for connecting said test circuitry to said device to be tested;
- and
- a connection board pluggably connectable to said contacts, said connection board pluggable to said contacts in a first configuration to insert a capacitance between said contacts, and pluggable to said contacts in a second configuration to insert a short circuit between said contacts.
