6634A

Keysight 6634A DC Power Supply

The Keysight 6634A Power Supply offers a set of precision resistance standards encased in a temperature regulated chamber. There are 10 standard resistance values accessible covering the range of 0.1 ohm to 100 Megohms. Every resistance element is isolated and incorporates a 4 terminal association on the back board. The resistance elements are maintained at 30 ± 0.01 degrees C in a temperature stabilized chamber. Resistance components are electrically isolated and bonded to an aluminum piece to decrease warm gradients in the inward chamber. The inward chamber is designed to electrically protect the single components and an electrical association is provided to a guard terminal.

The design of the 6634A lessens thermal bridges between the control and monitoring circuits and the resistance components. The distinctive resistance component design is based on the proven Guildline model 9334 Resistance Standards and accomplishes phenomenally in length term solidness and low power coefficients.

This model has a Resistance Range between 0.1 る to 100 Mる in, includes Single Decade Increments, has a Temperature Coefficient of ± 0.005 ppm/0C, has stabilities as Low as < 2 ppm/year, Thermometry Value Models Available, 4 Terminal Connections, Eliminates Oil Bath Requirements, Ha Internal PRT Stability of ±0.020C / Year, Custom Internal Temperature Set Points, an Ambient Temperature Range between 230C ± 50C, has Low Thermal EMF’s – Shielded Chamber, a Temperature Regulation of ± 0.01 degrees C over a 1 year period, and has a Guarded Resistance Element Chamber.
