From the P7700 Series documentation I have found specification for P77STFLXA and P77STFLXB solder in tips. I have below queries, please clarify.

* What is the difference between P77STFLXA and P77STFLXB i.e A & B. Why espicially mentioned A & B at the end of the model name.
*For P77STFLXB, In P7700 Series documentation I have found that we can use for Flex circuit based DDR4/LPDDR4 memory solder in tips. Specifically mentioned DDR4 but for P77STFLXA they didn't mention any DDR4 like that. So can you briefly explain why and confirm whether we can use that for LP-DDR4 3200.
* What is the specification of P75LRST, especially temperature range and also please assist me to get a datasheet of  P75LRST probe tip.
 

Hi
Thanks,

* P75LRST probe tip is High performance solder tip with long reach type.

* From above statement, I understand that you will provide S - parameter files only for performance solder tip, If it was with long reach type you will not share those files (or) there will be no S - parameter files for long reach type. Please confirm.

* If S - parameter files are having for the P75LRST, can you please help me how to get those S- parameter files.

*If S - parameter files are not having for the P75LRST, can you please suggest an alternative probe tip which having same parameters and also consisting with S - parameter files.

*Sharing an example probe tip image

S - Parameter files of Differential ended (.s6p) and Single ended (.s3p) for Trimode probe P7513A & Probe tip P75LRST are needed for creating filter files in SDLA application. Please provide.
