CV unit Modifying the High Frequency or Low Frequency Pulse Width parameters results in a change to the number of cycles of the transmit signal applied to the transducer The numerical values shown correspond to the actual number of cycles transmitted For example if the Freg High Channel is set to 200 and the HF Pulse Width is set to 2 then 2 cycles of 200kHz signal 1O0usec worth is transmitted A rule of thumb is in shallow water use as few cycles as you can get by with while in deep water use as many as it takes Taken together with the Tx Power control setting pulse width directly influences the total amount of acoustic energy generated 4 4 5 3 TVG curves The TVG Curve value determines which Logarithmic scale the Echotrac CV uses In shallow water the 10 log should be used Multiple TVG curves are programmed into each of the unit s transceivers The 20Log Time Varied Gain curve is the generally accepted standard in single beam vertical echo sounders and the default value for the Echotrac CV The 20Log curve includes compensation for both spherical spreading loss and absorption losses The 40Log curve is the standard for use with the Side Scan option while a 30Log curve is also made available for special conditions The 10Log scale is intended for use in calibration bar checks The Manual parameter is intended for use in very shallow water applications where the special shallow water transducer is employed Once Manual is selected

32. you have noticed that the measured draft or the distance from the face of the transducer to the water s surface is not the same as the draft value entered into the sounder then you have seen the result of lumping both together This phenomenon is most evident when using dual frequency transducers where both high and low elements are in the same housing Often the draft values are very different for the two frequencies if no adjustable k parameter is incorporated The difference in k or electronic delay between a 200 kHz element and a 24 kHz array is substantial and is the reason behind the difference between the two Calculated Drafts Once the k value is determined it will not change until either the sounder or the transducer is changed The Index parameter should be adjusted to make the measured draft and the calculated draft equal Since the accuracy of measuring the depth depends on the value used for the velocity of sound in water along with the other factors shown above it is important that a realistic value for sound velocity is used In water velocity is a function of temperature salinity and pressure Therefore the sound velocity in one area may vary from the sound velocity measured in another area This means that whichever type of echo sounder is used it must be calibrated in order to provide the most accurate depth data at a given location The most common calibration technique is the Bar Check method This method
