4.2.10 Trace Memory
FIGURE 4–10: Setpoints Page 1 – PQM Setup / Trace Memory
This feature involves a separate sampling data stream. All input channels are sampled
continuously at a rate of 16 times per cycle. Using a single-cycle block interval, the input
samples are checked for trigger conditions as per the trigger setpoints below. Note that
the normal sampling burst (64 samples/cycle, 2 cycles) used for all metering calculations is
done on top of the trace memory sampling. The harmonic analysis sampling (256 samples/
cycles, 1 cycle) causes the trace memory sampling to stop for one cycle whenever a
harmonic analysis is requested. Refer to Chapter 6 for details on trace memory
implementation in EnerVista PQM Setup.
