Changing Readout Frequency

NOTE. The 1705A must be returned to the normal operating routine before the front-panel push-button switches perform the label functions. Push the INPUT push button as many times as required to bring up the spectrum analyzer display.

The 1705A readout normally displays the frequency of the L-Band or 70 MHz input signal. The L-Band input is a downconverted signal between 900 to

2000 MHz, which by itself does not return meaningful information. Because of this it may be easier to display the readout that corresponds to the actual satellite
