I have the Rigol 1052E model which is the basic two channel color digital scope rated to 50 mhz. Its the least expensive of their scope line. You can go to the website mentioned or just contact the Rigol people directly. Our club has the spectrum analyzer in addition to the scope and they work just fine. Rigol is adding new products regularly so it might be worth contacting them directly. We have had some questions about how to perform some measurements and the technical support crew who answered the phone gave us everything we needed.
Hope this helps
Thanks, Ken. I was impressed with the Rigol technical support person with whom I corresponded on another issue. Very courteous, patient, and helpful. Good suggestion!
