Accessories for HP, Agilent and Keysight LCR meters and Impedance Analyzers

The following accessories are useful for owners of LCR meters, to evualate the performance of your instrument. These are built using components that are considerably more accurate than the LCR meters themselves. These are 4-terminal pair resistors. For those thare regulary do RF work, the 50 Ω resistor is particularly useful. All these accessories can be used with meters having 4 terminal pair connectors (4 x BNC). These are sold at considerably lower cost than the Keysight parts. These parts are equivalent to the following Keysight items, but use closer tolerance resistors.

A replacement 100 Ω resistor for the HP/Agilent 4285A LCR meter

99% of HP or Agilent 4285A Precision LCR meter sold do not come with the 100 Ω resistor, 04285-61001. The Kirkby Microwave replacement uses a 0.01% resistor, which is 10x more accurate than the 4285A meter, and better than the resistors used in the Keysight Standard Resistor kits, such as the 43020A, where the 42036A resistor is 100 Ω +/- 0.1%. Our resistors also have a lower temperature depedance than the Keysight ones.

Standards available

LCR meter (optional)

Pay the carriage and insurance, and provide a telephone number to aid the courier deliver the calibration kit. The amount depends on the delivery location.

Note, this is for the carriage and insurance. There may be import fees and duties when the calibration kit is exported outside the UK. We have no control over these fees.

You can optionally provide the make and model of your LCR metes or impedance analyzers. This may help us improve support.
