Using the 1705A for Satellite Communication

The 1705A has two separate inputs, one, the L-Band Input, is specifically designed to work with LNB down converters, which have an output signal range of 0.95 to 1.80 GHz. This provides a means of looking at the signals from either Ku or C-Band satellites. The second input is identified as 70 MHz and accepts signals from 45 to 100 MHz. This second input is primarily designed to work with the IF frequency of an exciter, but can also be used to look at signals in the low VHF television band and the FM broadcast band up to 100 MHz.
