Additional information
Communication protocols and satellite test functions depend on ordering options and software configuration; they are not all included by default. 8T/8R describes RF ports, while the instrument has one VSA/VSG unit, not eight independent analysis/generation units. Typical and conditional specifications apply under their corresponding conditions. Price, configuration, accessories, lead time and final supply scope follow the quotation.
