Simrad SP90TVG (Time Variable Gain)The TVG button is located in the following menus: Horizontal,Vertical and Second Ping.The TVG controls the gain in the signal amplifier. The gain isweakest just after the ping, and increases in accordance with time(and therefore range).The TVG reaches the maximum gain at approximately 1500meters. In addition to Off, the TVG can be selected with fivedifferent curve slopes, each having different gain regulations. The20 log R line in the menu is marked with an asterisk to indicate thetheoretically correct setting. With this setting, the gain is adjustedin such way that a school of fish with a certain size and density willbe presented with approximately the same strength on the screenin any position inside the regulated TVG range.138 850-164511 / B
ParametersTx PowerThe Tx Power button is accessed from the following menus:Horizontal, Vertical and Second Ping.The TX Power is used to select the transmitter output power. Notethat the TX Power parameter is common for all the menus. Thus,if the Tx Power is changed in one menu, it will automatically alsobe changed in all other menus.The transmitter operates with three different power settings inaddition to Off (passive). The output voltage can be checked on thevoltmeter in the Transceiver Unit. The following values areobtained:Full - 100VMedium - 50VLow - 25VNote that the output voltage can drop as much as 20% during thetransmission pulse.850-164511 / B139
