摘要： A system is provided to enable leakage current measurement or parametric tests to be performed with an isolation buffer provided in a channel line. Multiple such isolation buffers are used to connect a single signal channel to multiple lines. Leakage current measurement is provided by providing a buffer bypass element, such as a resistor or transmission gate, between the input and output of each buffer. The buffer bypass element can be used to calibrate buffer delay out of the test system by using TDR measurements to determine the buffer delay based on reflected pulses through the buffer bypass element. Buffer delay can likewise be calibrated out by comparing measurements of a buffered and non-buffered channel line, or by measuring a device having a known delay.

摘要： A series of pulses may be driven down each drive channel, which creates a series of composite pulses at the output of the buffer. Each composite pulse is a composition of the individual pulses driven down the drive channels. Timing offsets associated with the drive channels may be adjusted until the individual pulses of the composite pulse align or closely align. Those timing offsets calibrate and/or deskew the drive channels, compensating for differences in the propagation delays through the drive channels. The composite pulse may be feed back to the tester through compare channels, and offsets associated with compare signals for each compare channel may be aligned to the composite pulse, which calibrates and/or deskews the compare channels.

摘要： A base controller disposed in a test cassette receives test data for testing a plurality of electronic devices. The base controller wirelessly transmits the test data to a plurality of wireless test control chips, which write the test data to each of the electronic devices. The wireless test control chips then read response data generated by the electronic devices, and the wireless test control chips wirelessly transmit the response data to the base controller.

摘要： A probe system for providing signal paths between an integrated circuit (IC) tester and input/output, power and ground pads on the surfaces of ICs to be tested includes a probe board assembly, a flex cable and a set of probes arranged to contact the IC's I/O pads. The probe board assembly includes one or more rigid substrate layers with traces and vias formed on or within the substrate layers providing relatively low bandwidth signal paths linking the tester to probes accessing some of the IC's pads. The flex cable provides relatively high bandwidth signal paths linking the tester to probes accessing others of the IC's pads.

摘要： A probe card of a wafer test system includes one or more programmable ICs, such as FPGAs, to provide routing from individual test signal channels to one of multiple probes. The programmable ICs can be placed on a base PCB of the probe card, or on a daughtercard attached to the probe card. With programmability, the PCB can be used to switch limited test system channels away from unused probes. Programmability further enables a single probe card to more effectively test devices having the same pad array, but having different pin-outs for different device options. Reprogrammability also allows test engineers to re-program as they are debugging a test program. Because the programmable IC typically includes buffers that introduce an unknown delay, in one embodiment measurement of the delay is accomplished by first programming the programmable IC to provide a loop back path to the test system so that buffer delay can be measured, and then reprogramming the programmable IC now with a known delay to connect to a device being tested.

摘要： A transmission line includes a signal conductor and at least one varactor diode capacitively coupled to the signal conductor. The transmission line's signal path delay is a function of its shunt capacitance, and the varactor's capacitance forms a part of the transmission line's shunt capacitance. The transmission line's signal path delay is adjusted by adjusting a control voltage across the varactor diode thereby to adjust the varactor diode's capacitance.
