Remarks


Supported instruments use cable compensation for the following operations:

  • SMU mode: to stabilize DC current sourcing in the two smallest current ranges

  • LCR mode: to compensate for the effects of cabling on LCR measurements

Note

This attribute is not supported by all instruments. Refer to Supported Attributes by Device for information about supported instruments.

For NI standard options, select the length of your NI cable to apply compensation data for a typical cable of that type.

For custom options, choose the source of the custom cable compensation data. You must then generate the custom cable compensation data.

Description

NIDCPOWER_VAL_ZERO_M

1121 (0x461)

Uses predefined cable compensation data for a 0m cable (direct connection).

NIDCPOWER_VAL_NI_STANDARD_0_5M

1153 (0x481)

Uses predefined cable compensation data for an NI standard 0.5m coaxial cable.

NIDCPOWER_VAL_NI_STANDARD_1M

1122 (0x462)

Uses predefined cable compensation data for an NI standard 1m coaxial cable.

NIDCPOWER_VAL_NI_STANDARD_2M

1123 (0x463)

Uses predefined cable compensation data for an NI standard 2m coaxial cable.

NIDCPOWER_VAL_NI_STANDARD_4M

1124 (0x464)

Uses predefined cable compensation data for an NI standard 4m coaxial cable.

NIDCPOWER_VAL_NI_STANDARD_TRIAXIAL_1M

1139 (0x473)

Uses predefined cable compensation data for an NI standard 1m triaxial cable.

NIDCPOWER_VAL_NI_STANDARD_TRIAXIAL_2M

1140 (0x474)

Uses predefined cable compensation data for an NI standard 2m triaxial cable.

NIDCPOWER_VAL_NI_STANDARD_TRIAXIAL_4M

1141 (0x475)

Uses predefined cable compensation data for an NI standard 4m triaxial cable.

NIDCPOWER_VAL_CUSTOM_ONBOARD_STORAGE

1125 (0x465)

Uses previously generated custom cable compensation data from onboard storage. Only the most recently performed compensation data for each custom cable compensation type (open, short) is stored.

NIDCPOWER_VAL_CUSTOM_AS_CONFIGURED

1126 (0x466)

Uses the custom cable compensation data supplied to niDCPower_ConfigureLCRCompensation. Use this option to manage multiple sets of custom cable compensation data.
