PM0830

| The PM0830 consists of eight
fully independent four-quadrant power sources. Two
of the channels are capable of supplying up to 30
V/500 mA each. The remaining six channels
are capable of supplying up to 30 V/50 mA each. The
PM0830 has a measurement range capable of
measuring voltages up to 1000V. The PM0830 uses an onboard controller, which relieves the system CPU of performing many functions necessary for the module operation. The result is higher efficiency of the CPU and faster execution of the module commands. All measurements use the “Zero Time Average” (ZTA) circuit (patent pending) that allows for a measurement time of less then 250 us to the full 16-bit resolution. ZTA enables the PM0830 to obtain the repeatability of using 20 to 50 measurements and averaging the results, with a single measurement. The PM0830 implements a calibration method called Hardware Error Correction (HEC) (patent pending). This method performs a full calibration, correcting errors for every code, as opposed to the more traditional two-point calibration of offset and gain correction. This method uses no CPU time, which accelerates the forcing and measurement functions. |
