When I clicked on the link, I got a DNS error so I had to find the document myself. 
I tried attaching the document to my post, but the file size exceeded the limit.

Hi
I read through the HP Digital probe guide and I did not find it that useful.

I have found that the proper digital pod is   54620-61601  originally made for the 54620 logic analyser.  Very expensive on e-bay.

I did a forum search for HP 54645D and went through all of the postings.    It looks like the cable 16510-61602 is compatible, but I don't know if it comes with the pods to connect the grabbers.

No, the cable is just a woven resistive cable similar to the original cable (but connecting to a single 16 channel pod instead of two smaller 8 channel pods). Although of course things may get sold on eBay in all kinds of combinations. The pods used are described on page 47-50 of the document you didn't find useful. Just search for "hp logic analyzer pod" on eBay. Try to find one with all leads and clips included still in its vinyl pouch. The label like pod 1, pod 5 etc doesn't matter, that's just a label.

The problem is that I haven't used a LA since 1986 so I am a little out of date.  Narrowing down the options to pg 47-50 helps a lot.  The table on pg46 only has one dot for 1650 series. 

I found a HP reference here https://edadocs.software.keysight.com/kkbopen/what-digital-probe-cables-and-accessories-are-available-for-keysight-mixed-signal-oscilloscopes-msos-589743268.html. 
It says the 01650-61607 cable was useful but I am not certain if these are all compatible with my HP 54546D scope. 

I did try plugging in a standard hard drive cable but the connectors have one pin plugged, so that doesn't work.  I found a seller nbhightech on e-bay that advertises "Agilent HP 10089A Logic Probe with Flying Leads for 54620C".  Sort of a semi DIY solution.  I assume the little pcbs have the passive terminator components. 

I have been looking at modules.  The module I have only includes RS232 and parallel port.  Not that useful these days  Ideally I'd like to get the GP-IB & maths module which is desirable but not essential for me.    The e-bay buy-now prices rule out that option.

I have also looked at options to replace the noisy fan.    The 80mm factory fan specs 47cfm which explains why it is so noisy.  A low noise Noctua NF-A8 or NF-R8 could be swapped in but their air flow spec is about half.  I need to do some further investigation before trying that mod.  Maybe I could add some vanes to better guide the air flow over the heat sinks to compensate for the lower gross airflow.  It would be worth it to get rid of the fan noise.

I have spent a little time finding my way around the user interface.  I can understand why these scopes are still so popular.  Very easy to use.
If there are deficiencies, it is decoding serial protocols and no published circuit diagrams.

I tried that search and got a lot of hits on pods but no pouches.  I am unsure whether these pods plug straight into the scope, or if there should be a cable between the scope and the pod.   Many listings include references to K,M&N clocks.  I don't know if that is something I need to worry about.
