13. EG Y file BASE GAIN In order to get the best imagery possible from analog profilers it is imperative that the National Instruments A D converter is configured with min max voltage levels as close to the observed voltage peak from your profiler Typically this is either the peak of the bang pulse the peak of the first bottom return or somewhere in between This optimal setting insures that you are getting the best resolution you can from the analog to digital conversion process In earlier versions you were limited to digitizing 5V A new Base Gain setting allows you to dial in the voltage range from 10 to 0 25 which to the eye works as a base gain Note that it is critical that the base gain is not set so high that it clips your data It s okay if you clip the bang pulse somewhat 38 TIME VARIED GAIN TVG Three Time Varied Gain windows can be specified to improve the displayed imagery In each the amount of gain applied to the signal increases with time and is in dB units over 1 second For example in Figure 45 TVG1 is set to 20 this means that the TVG curve is configured so the sample 500 milliseconds down the signal trace will be amplified 10dBs 1 second down by 20dBs and so on TVG1 begins at the start of the signal Don t overdo this one as it will amplify the bang pulse and water column noise in addition to everything else Sliding TVG1 all the way to the left will set it to B for blanking This
