PM0825

|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| The PM0825 consists of 8 fully
independent four-quadrant power sources capable
of supplying up to ±20V. Two of the sources are
capable of up to 500mA each, four more are capable
of performing at low levels with ranges of 1uA
and 100uA; the remaining two are mid range with
current ranges of 1mA and 100mA. The PM0825 is
designed to cover a wide range of requirements
within on resource. All the modules are of
continuous type, however, they are thermally
protected and will go into a shutdown mode if the
temperature on the output transistors gets to
dangerous levels. The measurement function has a patent pending circuit called the "Zero Time Average" (ZTA) circuit that allows for a measure time of less than 250 us to the full 16 bit resolution. ZTA enables the PM0825 to obtain the repeatability of using 20 to 50 measurements and averaging the results, with a single measurement. The patent pending calibration method implemented on the PM0825 corrects for errors in a way that uses no CPU time, speeding up the forcing and measurement functions. This method also implements a full calibration, correcting the errors for every code, not just the more traditional 2-point calibration of offset and gain correction. |
