Simplify Multiple Bias Voltage Sequencing and Ramping for PC Motherboard Test
应用文章
Problem
Sequencing and ramping multiple bias voltages to specified timing conditions during test is difficult or impossible to do with separate programmable system power supplies. Even most conventional multiple-output system power supplies do not adequately address this need.
Solution
- Keysight Technologies, Inc. N6700 Modular Power System incorporates several features ideally suited for sequencing and ramping multiple bias voltages during test:
- The N6700A-B mainframe holds up to 4 output modules in a 1-U package for high system density.
- Programmable precision delay and slew rate controls for each output provide exacting output voltage sequencing and ramping within a mainframe.
- Fast (< 1 ms) command processing time provides a simple means to sequence additional outputs across multiple mainframes. Alternately the hardware trigger system can be used to synchronize multiple mainframes.
- The N673xB 50W and N674xB 100 W, 5 V to 100 V basic power modules are economical choices when the primary focus is powering the PC motherboard.
- Up to four identical power modules can be paralleled and operated as a virtual single output for greater current and power.
