The DSM1 DUAL SIGNAL METER is intended to aid in the alignment of a satellite dish. It includes a satellite IF (950-2150 MHz) amplification and a broadband detector. The detector drives a meter and a variable frequency audio tone. The dish is then aligned for maximum meter deflection or highest pitch tone. A gain control allows a wide range of input signal levels.
The unit is connected to the LNB via a short coaxial cable. Connection to the receiver is optional but extends battery life between charges.
It allow measurement of voltage on the coaxial cable. It will also measure LNB current. An internal rechargeable NiCad battery pack, carrying case/strap and a wall plug recharging unit are included. The internal battery pack allows a dish to be aligned before it is connected to the satellite receiver. The battery pack is switchable between 13 and 18V output, allowing either polarization to be selected when used with a voltage switched LNB. In US DBS applications, LHCP is selected when the LNB voltage is nominally 17V.
DSM1 includes two meters in one housing, allowing easy alignment of dual satellite single dish installations. When peaking, the dish signal level can be viewed for both LNBs simultaneously, making alignment quick and easy. This unit is similar to the Channel Master 1008IFD.
