Our Agilent VNA E5071C is dead. It was diagnosed by an ex HP technician that its motherboard and its receiver board are both dead, and for the receiver board we need to replace a dead SMT chip "Agilent 1GM1-4233".
Our HP technician doesn't want to take the risk purchasing this chip from an uncertain source online. He wants to find its data sheet first and possibly its original manufacturing part number (instead of this Agilent's part number 1GM1-4233). However, he hasn't been able to find its data sheet. Does anyone here know some tricks finding data sheets for special chips?
