from UTC (UTC -12 to UTC +14). The precise
UTC time can be received e.g. by navigation
satellites.
VBW Video bandwidth
Video bandwidth
The VBW is used to smooth the signals,
particularly to reduce the noise. The selected
VBW influences the sweep time. The smaller
the VBW selected, the more the noise will be
smoothed but the longer the sweep time will be.
WAV Wave file format The WAV file format is a container format for
saving audio data, which can contain
compressed audio data in addition to the
uncompressed PCM raw data. It is the de facto
standard for storing audio data on MS Windows
