Many parameters of HERA machine components such as RF systems or quench protection as well as important beam parameters are continuously measured using transient recorders. In general, these recorders are not synchronized among one another and sample the data with very different rates ranging from 200 Hz to 50 MHz. At present, work is going on to integrate the different existing transient recorders into a global system. The article reviews the transient recorder hardware in operation at HERA. In addition, the proposed trigger distribution based on the HERA Integrated Timing system as well as the software concept to archive, retrieve and display the data will be described.
