Agilent DSO5014 fix and BWhack

[qzqmom]

Hello Everybody !
Nowdays  I bught a broken DSO5054 （the panel label said that) but the main board  number is
54534-66401  not 54574-66401 as service manual record. And every analog channel have inb7-8453 that turely used on 300/500m dso6000series .
I can't found any internal pictures about DSO 5000
Series on internet and confused about its model.
So does anyone have the internal pictures about this oscilloscope  . If it's a DSO 5054 OR DSO5014
?And should inb7-8453 module shown on a DSO 5014 board?

This machine lost DC-DC convert board and main board had rework the bnc Connector are replaced by a new 2ch machine bnc Connector

I cost ￥100 for a broken power supply board and fixed it ，there also need two flex cabel so ibought connector and start handmade，after all these matter，I contact power cable and it work ，unfortunately the main board model is dso5014😅，but all channel worked  cuz it have inb7-8453 we can hack BW easily by move the model resistor

After resistor hack Now I get a DSO5054 without bnc connector😂

some who just have a 5014 with inb7-8453 internal could have a try ，I can't test if the BW is truly increased to 500m ,maybe there still have a RC
network should have modification ,. By the way you can also remove the resistor and make your 5054
to a 5014 ,🤓haha
