USB Operation
Starting with software version OutG SW 1.0.688.18, the USB memory operation offers a
variety of capabilities. As an example, a USB device can be used to store readings either
directly from the A/D or by transferring readings from internal memory. The data stored
in the USB memory device is in a comma delimited (CSV) format.
USB Storage Capacity and Write Time
The 8846A USB storage limit is 50,000 readings every time START is pressed (F1 soft
key press). Previous versions stored 50,000 readings in 10 files, each with 5,000 readings.
This version stores 50,000 readings in five files, with 10,000 readings each.
If storing readings to the USB memory device is not completed (or is interrupted by
changing function, NPLC, remote...), press MEMORY, MANAGE MEMORY,
INIT MEAS TO USB so volatile readings in internal memory are stored to the USB.
