Overlapped measurementsare always stored in a reading buffer. Synchronous measurements return either a single-point measurement orcan be stored in a reading buffer if passed to the measurement command.The dedicated reading buffers can be saved to internal nonvolatile memory (to retain data between powercycles) using the smuX.savebuffer() function.Examplesmua.measure.overlappedv(smua.nvbuffer1) Store voltage readings from SMU channel Ainto SMU channel A dedicated readingbuffer 1.Also seeConfiguring and running sweeps (on page 3-29)Reading buffers (on page 3-6)savebuffer() (on page 7-161)smuX.makebuffer() (on page 7-197)smuX.measure.overlappedY() (on page 7-209)smuX.savebuffer() (on page 7-216)smuX.trigger.measure.action (on page 7-241)smuX.trigger.measure.set() (on page 7-241)smuX.trigger.measure.stimulus (on page 7-242)smuX.trigger.measure.Y() (on page 7-244)
