Rental/Lease Information Request

The 70600A provides optional preselection for the 71200C microwave spectrum analyzer. A preselector eliminates the image and multiple responses generated by the harmonic mixing technique used in the spectrum analyzer. A built-in attentuator in the preselector provides overload protection and allows you to set the proper input level to the 70905A/B RF Section for optimum dynamic range.
