KEITHLEY 228 Programmable Voltage/Current Source

100 Watts, Programmable Voltage/Current Source: Capacity to sink or source up to 100 Watts. Constant voltage source has ranges of 1 V, 10 V, and 100 V. Constant current source has ranges of 0.1 A, 1 A, and 10 A. Actual output voltage and current are continuously monitored and displayed on the front panel. These values can also be read back over the IEEE bus. Dual 3-digit LED displays indicate programmed values in Standby and output values in Operate.

*This is a Web introductory price for one calibration of the KEITHLEY 228. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Average Power
Average power means that the energy transfer rate is to be averaged over many periods of the lowest frequency involved. For a CW signal, the lowest frequency and highest frequency are the same, so average power and power are the same. For an amplitude modulated wave, the power must be averaged over many periods of the modulation component of the signal as well.

Dynamic range
Dynamic range the ratio of a specified maximum level of a parameter, such as power, current, voltage or frequency, to the minimum detectable value of that parameter.

Modulation
Modulation is the process by which the characteristic of one wave (the carrier) is modified by another.

Repeatability
Repeatability is the variation in a number of repeated measured quantities when measurement conditions are changed and restored. The value corresponds to half the spread between the minimum and maximum value measured.
