FLUKE 720A Kelvin-Varley Divider

The Fluke 720A Kelvin-Varley Divider is a high-resolution primary ratio standard with absolute linearity of 0.1 ppm, temperature coefficient of linearity of 0.1 ppm/°C, and self-calibration capability. Specifications. Ratio Range: 0 to 1.0 (1 .0 input tap) and 0 to 1.1 (1 .1 input tap). Resolution: 0.1 ppm of input with seven decades. Absolute Linearity: (At calibration temperature and without the use of a correct chart) ±0.1 ppm of input at dial settings of 1.1 to 0.1, ±0.1 (10S) ^1/3 of input at dial settings (S) of 0.1 to 0. Temperature Coefficient of Linearity: ±0.1 ppm of inputl°C maximum at dial settings of 1.1 to 0.1. Short-Term Linearity Stability: Under typical conditions in a standards laboratory environment (temperature maintained within ±1 °C) and with an applied voltage of up to 100 V, stability of linearity is 0.1 ppm/30 days. Power Coefficient of Linearity: ±0.2 ppm of input/W max at dial settings of 1.1 to 0.1 ; ±0.2 (10S)^2 ppm of input/W max at dial settings (S) of 0.1 to 0. Maximum End Errors: Zero error at output low: 0.004 ppm of input. Zero error at input low: 0.05 ppm of input. Full-scale error: 0.05 ppm of input. Thermal Voltages: ±0.5 µV max. Maximum Input Voltage: 1000V on 1.0 input terminal, 1100 V on 1.1 input terminal. Input Resistance: 100 k-ohm ±0.005% at 1.0 input terminal at 25°C; 110 k-ohm ±0.005% at 1.1 input terminal at 25°C. Temperature Coefficient of Input Resistance: ±1 ppm per °C max

*This is a Web introductory price for one calibration of the FLUKE 720A. 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.

Channel Bandwidth
Channel Bandwidth is the bandwidth over which power is measured. This is usually the bandwidth in which almost all of the power of a signal is contained.

Jitter
Jitter in technical terms is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. Jitter is the time variation of a periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals. Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48). In clock recovery applications it is called timing jitter.

Overshoot
Overshoot is the distortion that follows a major transition; the difference between the peak power point and the pulse-top amplitude computed as a percentage of the pulse-top amplitude.

Rise Time
Rise time refers to the time required for a signal to change from a specified low value to a specified high value, usually 10 and 90 percent of pulse-top amplitude (vertical display is linear power).
