On older systems this was a simple chart recorder, on modern systems a computer with hardware interface and display is used.

Returns were also processed and made available to the RO-358 chart recorder in the AQS-13E and earlier systems.

Later models had improvements such as centralized control of switching, central measurement bays, and chart recorders to automatically provide permanent records of results.
15.
The RO-358 chart recorder provided a means of recording a permanent record of target data as well as additional means for target evaluation.
16.
In analog strip chart recorders such as used in electrocardiographs, electroencephalographs and polygraphs, galvanometer mechanisms were used to position the " pen ".
17.
Circular chart recorders have a rotating disc of paper that must be replaced more often, but are more compact and amenable to being enclosed behind glass.
18.
However, dataloggers'decreasing cost and power requirements allow them to increasingly replace chart recorders, even in situations where battery power is the only option.
19.
Roll chart recorders are similar to strip chart recorders except that the recorded data is stored on a round roll, and the unit is usually fully enclosed.
