N6700C FAQ
- What makes the N6700 popular for ATE applications?
The N6700C combines up to four outputs in a compact 1U rack-mount form factor, delivering up to 400 W of total output power. It offers flexible module selection, integrated measurement capabilities, and high-speed system communication. The N6700C is an ideal choice for systems that require multiple low-power modules or when DUT channels are unlikely to draw high power simultaneously. These features make it a popular solution for automated test equipment (ATE), design validation, manufacturing test, and R&D applications. - Can the N6700C outputs be connected in series or parallel?
Yes. The N6700C supports power modules whose outputs can be connected in series to increase voltage or in parallel to increase current, depending on the application and module specifications. This flexibility allows engineers to configure the power system for a wider range of DUT requirements without adding additional power supplies. - Does the N6700C include measurement and data-logging capabilities?
Yes, measurement capabilities are provided through the installed N6700 Series power modules. Depending on the module selected, users can monitor voltage, current, and power, while advanced modules offer features such as high-speed digitizing, waveform capture, arbitrary waveform generation, and precision current measurements. The system also integrates with Keysight BenchVue software for instrument control, data logging, and test automation.
