Looking to purchase a Profibus Diagnostic Meter... Any Suggestions?

The number of problems that got blamed on the Profibus networks in a factory I work in went down by half once we got a Profitrace unit:

Some of that is because we now have a very powerful and precise tool to track down bad signals, bad connections, and bad devices, so we've fixed a few of them and know the characteristics of the intermittent ones.

And some of it is because now the network isn't mysterious; folks know we can exclude the network as the source of the problem and are more willing to pursue end-device, power supply, and system operational reasons why something doesn't turn on when they expect it to.

We have multiple Profibus networks, some are on a Controllogix 1756-PFB-CLX card. And some are connected to a Siemens S7-300 PLC.
Just wondering if there is a preference on a good diagnostic scanner for these two networks.
Thanks

We used a Fluke Scopemeter when we were having ModBus difficulties, the new model does Profibus too among a few others, very useful tool all round if you haven't got a scope either:

The Test Tool can indicate the status of the following
aspects of the OSI model Physical Layer:
• Voltage levels (bias, high level, low level)
• Bit width – baud rate
• Rise and fall time
• Distortion

Out of curiosity I looked through the specs and the manual. In the manual it just says:
"Profibus - DP PA - EIA-485 61158 type 1"
Nothing more, in the entire manual.
