The Fluke 98 can capture long records of hundreds of divisions but does so at a very slow maximum sample rate of 1.25khz. You can't set the time base any faster than 20ms per division in continuous record. Here is an example. The 98 is capable of 25mhz but will only capture 10 divisions at that speed. The 97 will capture 20 divisions at 25mhz but has no scope record.
Ease of use is another issue.
You can't just pick up a Fluke 97 and use it. Plan on spending some time with study and practice. But for those who have mastered it, the power is awesome. Choosing an instrument is a personal thing based on need, ability, budget and time. But when going into battle with evil demons you need all the power you can get.
