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,
.
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.
4.8

Average

Sets the signal averaging. The device will take multiple waveforms and then average
them.
4.9

Polarity (Tone Burst Pulser Only)

Sets the polarity of the tone burst pulser. Positive polarity starts the oscillation with a
positive pulse while negative polarity starts the oscillation with a negative pulse.
