An additional component to the JTAG/Boundary Scan hardware platform Scanflex, the SFX-5704 was developed for the production test of mixed-signal applications and provides four parallel and independent channels as well as a number of additional resources and special functions. This I/O module can be freely combined with all Scanflex controllers on PCI, PXI, USB, FireWire or LAN basis as well as all Scanflex TAP transceivers with distances up to 5m. Each of the four channels features a fully-fledged driver/sensor pin combined with an analogue measuring function. For digital tests each channel can be switched to input, output, bidirectional or tri-state (interposing relay). A multitude of individually programmable parameters such as input voltage (±10V), output voltage (±10V), maximum driver current up to 300mA and programmable pull-up and pull-down resistors enable an application-oriented test-channel adaptation to the signals being tested. The analogue measuring function has an input range of ±10V at a 12-bit resolution. Analogue and digital functions can simultaneously be operated at active clip switching.
