Description
Description
When running the NP02 coldbox (first minute of run 40915), there was a run taken with the RTCM with a rate of 0.01Hz, but no TCs were generated. This was only fixed when the rate was changed to 0.1Hz. The changes to the base 5.4.3 vd-coldbox configuration included (and are verifiable from the run registry):
- tBefore = 0.5ms
- tAfter = 2ms
- mlt post processing ticks = 0
- tpg disabled
Steps to reproduce
Setup a 5.4.3 area
Create a run using the NP02 CB with the above instructions.
Observe no TCs being generated with a rate of 0.01 Hz.

Research direction
Reproduce the issue in an fddaq-v5.4.3 NP02 coldbox setup using run 40915's first-minute conditions and a 0.01 Hz RTCM rate. Compare the behavior with 0.1 Hz while keeping tBefore, tAfter, mlt post-processing ticks, and tpg settings as described. Done means random TC maker RTCM generates TCs at the low trigger rate.
