Keithley707B系列半导体开关系统suited for both lab and fab Like their predecessors, the Models 707B/708B are specifically designed for the requirements of both semiconductor lab and production test environments, delivering ultra low current switching performance using standard triax connectors and cables . For automating smaller test systems with a limited number of pins and instruments, the Model 708B supports a single switch card with up to 8 rows and 12 columns (8×12) . For applications requiring higher switch counts, the Model 707B can accommodate up to six 8×12 cards, which can be connected via an internal backplane or jumpers to form larger matrices . Both mainframes also support mixed signal switching for both DC and RF (up to 200MHz) signals .
