| Description | COMPARISON OF AC/DC VOLTAGE TRANSFER STANDARDS |
| Time of measurements | 2018 - |
| Status | Report in progress, draft A |
| Measurand | AC-DC voltage transfer difference Voltage: 3 V Frequency: 0,5 MHz, 1 MHz, 10 MHz, 30 MHz, 50 MHz, 70 MHz and 100 MHz |
| Transfer device | NIST 3 V Multijunction Thermal Converter |
| Comparison type | Key Comparison |
| Consultative Committee | CCEM (Consultative Committee for Electricity and Magnetism) |
| Conducted by | CCEM (Consultative Committee for Electricity and Magnetism) |
| Comments | The circulation of the travelling standard started Dec 2018 but due the pandemic and other delays it has taken longer time than planned. The measurements were finalized in July 2024 by the pilotlab NIST and INTI is now working on the Draft report A of the comparison. |
