4-port E5071C vs N5230A

Hello,

I used 4-port E5071C to measure twisted-pair cables and differential channels on PCB. Basically, it can cover S-parameter measurements and provide .s4p file.

Now we need to purchase a VNA for our new lab. The 4-port PNA-L N5230A shows similar capabilities.

From what I can find online, it looks like the N5230A cannot do true balanced measurements. Is it one of the critical differences between E5071C and PNA-L N5230A?

What other differences do I need to consider for purchasing one over the other?

Really appreciate feedback from users who have experience using both models.

Thanks.
