FLUKE 752A Reference Divider

The Fluke 752A Reference Divider sets new standards for direct voltage ratio accuracy and ease of use. It offers two divider outputs, 10:1 and 100:1 with output uncertainties of less than 0.2 ppm and 0.5 ppm respectively. Before each use, the 752A is easily calibrated with only a stable voltage source and null detector like the Fluke 845AB or 845AR. The entire procedure requires only five minutes and does not require external standards. The 752A also includes internal switching for calibrating the 100 mV, 1V, 10V, 100V, and 1000V ranges of a voltage calibrator to a 10V reference source (such as the Fluke 732A dV Reference Standard) without having to change the lead connections. It provides the voltage division capability required to calibrate state- of- the-art calibrators and similar instruments. A "self-calibration" procedure allows you to compensate for long term changes in value of the divider resistors by switching their positions in various Wheatstone bridge configurations and using the BALANCE pot on the front panel. Specifications. Ratio Ranges: 10:1 and 100:1. Temperature Coefficient: <+1 ppm per °C over range of 18°C to 28°C (typically 0.1 ppm per °C from 15°C to 30°C). Input Resistance 10:1 Ratio: 380 k-ohm ±1%. Input Resistance 100:1 Ratio: Divider is 4 M-ohm; Driven Guard is 4 M-ohm; total is 2 M-ohm ±1%. Maximum Input Voltage: 200 V for the 10:1 ratio; 1100 V for the 100:1 ratio. Power Coefficient: <= 0.05 ppm of output with 100V applied for 10:1 ratio and <=0.3 ppm of output with 1000V applied for 100:1 ratio (included in the ratio accuracy specifications).

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.

dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.

Load Regulation
Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Settling Time
Settling time of an output device is the time elapsed from the application of an ideal instantaneous step input to the time at which the amplifier output has entered and remained within a specified error band, usually symmetrical about the final value.
