It has all the basic functions of "WDQ_Edit", plus functions for converting WDQ files to WinQuake PSN TYPE 4 format. We use a slightly modified WWVB-controlled wall clock (Atomix brand supplied by Chaney Instrument Company) to generate accurate one-minute marks on our recordings. We have attached a small aluminum foil reflector to the second hand. An external LED source and phototransister assembly is used to detect passage of the second hand past the even minute time. The HeliPlot detailed waveform display shows the marks as vertical blue lines. Most of the time, the wall clock is very accurate. At certain times of the day, it goes through an alignment routine with the WWVB signal. For a minute or two, it can be almost a second fast.MENUS: File: Open Plot (Use after Open and after changing channel, gain or filter menu choices) Channel 1 Channel 2 Channel 3 Channel 4 Output (Save a filtered version of the displayed channel) Close (Not really needed) Exit Filter: No Filter (U) Differentiate (For high frequency emphasis) (D) HighPass (High pass filter, of corner period entered when chosen) (H) LowPass (Low pass filter, of type and corner period currently set up)(S) BandPass (Cascade of HighPass and LowPass) (B) Long Period (Cascade of LowPass and Broadband)(L) Broadband (A special filter for extending the effective period of the pendulum)(X) Form: 6 Hours 13 Hours 25 Hours Custom (User specified hour lines) Copy: Drum (copies the heliplot image to the ClipBoard) Detail (copies the detail plot image to the ClipBoard) View: Detail Screen ON/OFF (Heliplot version only) Header (Shows file header information in a dialog box) Settings (Details on filter settings) Update Rate: No Update (Real time plotting is suspended) Normal (Real time updates are every 256 data sample intervals) Slow (Real time updates are every 768 data sample intervals) Gain: (control of display scale) 1x, 2x, 4x, 8x, 16x, 32x Filtered Gain (2X, 1X, 0.5X) SeisCal: Set Up Smoothing (Opens a dialog box for selecting filter type and corner period for each channel) Set Up Long Period Filter (Opens a dialog box for setting up long period filter for each channel) Help: About HelpLONG PERIOD FILTERING: A pendulum type sensor does not detect well frequencies below the natural period of the pendulum.
