4-2
4.5 DC
Offset
Sets the DC offset of the signal.
4.6 Buffer
Length
The buffer length specifies how many samples the USB-UT350 will analyze during data
acquisition. This value can be anywhere between 2 and 8191 samples,
or 1 to 32000 with
32K memory option
.
4.7 Trigger
Delay
The trigger delay specifies how many samples the A/D converter should skip before
processing the response signal. This value can be anywhere between 0 and 16,383
samples.
