Someone in thread said it once and I will repeat. What are you trying to do? >From a millihertz to a Ghz is one heck of a range with milihertz res to boot for under $1K. Thats a cross between an old HP 3335 and a 8660 series with decreasing resolution on increasing frequency. If there is such a beast for under 1K I may want to buy one also. Regards Paul.
