Enabling the High-Resolution Feature

Enabling the High-Resolution Feature

Note: This feature applies only to the FTB-2 and FTB-2 Pro platforms.

You can select the high-resolution feature to obtain more data points per
acquisition. This way, the data points will be closer to each other, which
will result in a greater distance resolution for the trace.

Note: When you test with the high-resolution feature, you should use a longer

averaging time to maintain a signal-to-noise ratio (SNR) that will be
equivalent to the one you would have had with the standard resolution.

To test the high-resolution feature, you must set a minimum
acquisition time of 15 seconds.
