LeCroy DDA-5005A probe options for full 5GHz bandwidth

Hello
I am thinking of buying a LeCroy DDA-5005A DDA to be used as an oscilloscope. Used units in ebay don't come with probes. I read in this forum that the connector type is different: more info in here:
https://amplifier.cd/Test_Equipment/LeCroy/DDA5005A_XXL/DDA5005A_XXL.html
Few questions:
1. If I were to measure up to 1GHz, can passive probes be used?
2. To go to max bandwidth, should I use active probes? Or can passive probes be used still?
3. Are there non lecroy probes that connect to the scope directly without a BNC converter?
4. The input is 4V peak to peak. Is it possible to protect this input from accidently applying higher voltages? say 12 V?
Thanks

This class of oscilloscopes used only as HF stuff. They have 50Ohm input, uncompatible with BNC type 10:1 probes.
You can use passive matched-line 50Ohm probes stuff, but only 4V peak to peak.
Or buying Lecroy active probe with 5:1 or so..
