Counterparts for following keysight equipments

Hello team - 

I am a new hire. I need help. I need to find counterparts for the following keysight equipments: 
 

P/N	Description
34980A-DMM	DAQ Mainframe
Y1130A	Rack Mount Kit
34950A	IO Card
34922A	MUX Card

The 34980A is a 6.5 digit measuring tool, but is full rack and 8 slots for cards to make it multi-channel tool.
If you need the high number of slots for cards, consider our model 3706A and the various 37xx cards.
The 3706A is a 7.5 digit measuring tool and has six slots for cards.

If number of slots for cards is not important, consider the 6.5 digit DAQ6510 which has two slots for various 77xx cards.
