I have used both and currently own the Tek THS720P. I did not like any of the Fluke scopes that I tried - the 95, 99, 123. On the 9x series scopes, the trigger was almost useless and they aliased horribly on slow signals (under sampled). A few months ago, a buddy asked me what I thought of the 199 which he had been demoing for the previous couple of weeks. He brought it over and I was able to show him that most of the problems that I saw on the early models were still there. I then loaned him my Tek. Bottom line - he bought 3 - THS730A for his company. Don't get me wrong - I don't think that the THS7xx is perfect. In fact, I don't use it much for analog stuff at all - I use my Tek 465. The handheld 720 is just too slow and noisy - I never can tell if the noise I am seeing on the signal is really there or not. But it is now the first instrument I reach for if I am troubleshooting digital stuff or power electronics (both analog and digital). I now consider the isolated grounds essential if I am working with industrial voltages. If you are looking to purchase one of these beasties, get the suppliers to send out demo units for a couple of weeks. You should be able to decide which one works best for your purposes. dwayne Dwayne Reid Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax Celebrating 17 years of Engineering Innovation (1984 - 2001) * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Do NOT send unsolicited commercial email to this email address.
