   KEITHLEY 228   Description / Specification:    
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.

Crest Factor
Crest factor or peak-to-average ratio (PAR) is a measurement of a waveform, calculated from the peak amplitude of the waveform divided by the RMS value of the waveform

Linearity
Linearity is the relative difference between the displayed power ratio, Dx/D0, and the actual (true) power ratio Px/P0 caused by changing the displayed power level from the reference level, D0, to an arbitrary displayed level, Dx.

Phase Noise
Phase noise is the frequency domain representation of rapid, short-term, random fluctuations in the phase of a waveform, caused by time domain instabilities. Phase noise (L(f)) is typically expressed in units of dBc/Hz, representing the noise power relative to the carrier contained in a 1 Hz bandwidth centered at a certain offsets from the carrier.

Sensitivity
Sensitivity is the minimum magnitude of input signal required to produce a specified output signal having a specified signal-to-noise ratio, or other specified criteria.
