What is the make and model number of your PMT or photodiode?

The PMT is an RCA Photomultiplier Tube 931B 

The photodiode is most likely going to be the Advanced Photonix 100-12-22-021

Hello @astreets45.

Would you kindly provide more information (or datasheet) about your PMT and photodiode.

Thank you for the model #'s.
The MCC 118 supports an input signal of +/-10V.

The photomultiplier tube and photodiode output a current signal, so an external signal conditioning circuit ("tweaking" as you called it) would be required prior to any connections to the MCC 118.  It would be up to the end-user to design in a signal conditioner.

My colleague found the following document, which may be a helpful reference; see page 28, section 3.1.3.

Hi :) So, if I were able to design the conditioning circuit, it could work with the MCC 118? Would it be difficult/expensive to include this conditioner?

The input signal to the MCC 118 should be +/-10 VDC.

We do not design signal conditioners, so we do not know the costs nor effort required to add a signal conditioner to your application.  Search online for off-the-shelf signal conditioning units if you'd rather not design your own custom unit.
