PSM1700 PsimetriQ user manual

5.4 Data streaming
The phase angle voltmeter and power meter modes have
the option of high speed data streaming. In this operation,
the window width for the measurement may be specified
from 660us to 100ms and the data for each measurement
window is transmitted over the communications in a
continuous stream. The window is adjusted to synchronise
to the measured frequency.
PsimetriQ buffers the data and transmits at the fastest
rate that is possible. The buffer depth is over 8000 data
values so more than 5 seconds of data can be captured at
the fastest rate of 1500 readings per second even if the
data is not read at all. If the window size is such that the
data can be read out in real time then data streaming can
continue indefinitely.
Once the data streaming window has been setup but
before the streaming has been started, the display
periodically shows the measured value. Once streaming
has been started, the display is blanked to minimise
processing overheads. Streaming can be stopped either
immediately (ABORT) or may be stopped but remaining
data continues to be transmitted until the buffer is empty
(STOP).
