This tool is used to obtain Horizontal to Vertical (H/V) spectral ratios from any type of vibration signals (ambient vibrations, earthquake…).
The example used for explanations is an ambient vibration recording. Download compressed signal file.
Contents
Loading and viewing signals
First load and view a signal.
H/V Toolbox
The toolbox may be opened in two different ways:
- if the signal window is already open clik on the H/V icon
- if the signal window is not open drag the file(s) from the file manager to the H/V icon
The toolbox shows up in the form it was previously closed, with the file name(s) in the header.
The toolbox contains set ups for windowing selection and processing, together with output parameters.
Comprises three tabs: 
Time tab
Divided into three parts
- Global time range
Used to select all or part of the signal to be processed.
Works like the Waveform/Cut basic signal processing under the Waveform menu.
When "Use only the properties of the first signal" is checked, all tracks use the time parameters (T0, End, Picks) of the top track.
- Time windows
Comprises 4 tabs: 
- Windowing results
Below Time windows a line gives the resulting selected windows, in all stations, with possibility to get the number of windows in each station through the View pop-up menu.
