iMAG SQUID parameters
If the Tune procedure takes longer than 45 seconds, you may see a pop-up window
indicating that there is a problem with iMAG communications. This message can be
ignored. It is due to the fact that the iMAG does not support GPIB communications during
an auto-tune procedure.
4.6 ACQUISITION PARAMETERS
The
Acquire
tab controls the data acquisition parameters. The Sample Rate can be adjusted
from 10 Hz to 10 kHz. The Settle Time defines the period of time to wait after the stage has
moved to a discrete position and before collection of a block of data. The Measure Time
defines the duration of a block of data to collect. The resulting block of data is processed to
calculate DC and AC components that provide a measure of the magnetic field strength at
the particular sample location.
