   KEITHLEY 480   Description / Specification:    
KEITHLEY 480 Picoammeter

The Keithley 480 is an easy-to-use, sensitive picoammeter that resolves 1pA. Simple controls, LED display, shielded BNC input, high normal mode rejection, and excellent overload specifications make it easy to use. The 480 measures DC current from 1pA per digit (2nA full range) to 2mA, with 31/2-digit precision. Seven ranges cover the full span of low-current measurements. The input is simply connected to the circuit under test, the appropriate range selected, and the current is read from the four 0.5 in LED digits with appropriate decimal point and polarity indication. Decade range of 1nA to 1mA, 1 pA to 1 uA resolution, and accuracy of 0.5%. The unit measures DC current from 1pA per digit (2nA full range) to 2mA, DC voltage input 20V to 600V.

*This is a Web introductory price for one calibration of the KEITHLEY 480. 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.

dBm
dBm (sometimes dBmW) is an abbreviation for the power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW). Zero dBm equals one milliwatt. A 3 dB increase represents roughly doubling the power, a 3 dB decrease, the power is reduced by about one half.

Millimeter-wave
Millimeter-wave is a term that generally refers to frequencies of 26.5 GHz and above. That is where signal wavelengths fall below approximately 10 mm, and thus the terminology changes from centimeters to millimeters.

Power Repeatability
Power Repeatability is the random uncertainty in reproducing the power level after changing and re-setting the power level. The power repeatability is ± half the span (in dB) between the highest and lowest actual power. Note: - The long-term power repeatability can be obtained by taken the power repeatability and power stability into account.

Stability
Stability is the extent to which a specified property, characteristic, or parameter of a substance, device, or apparatus, remains fixed with the passage of time or with varying environmental conditions.
