Keysight offers multiple interface options for the E4980A.

• E4980A-201 - Adds handler interface with 9 BIN outputs
• E4980A-301 - Adds scanner interface with 128 multi-channel core
• E4980A-710 - No Interface; Attaches blank panel to the expansion slots

Up to 2 interfaces can be installed in the expansion slots on the rear panel. When no interface is added, two of the E4980A-710 are installed. When one interface is added, that interface and the E4980A-710 are installed.

Both interfaces have standard compatibility with other LCR system instruments (e.g. 4284A/88A/78A, etc.) for easy integration into systems. The multi-compensation function enables open/short/load compensations to perform scanning measurements independently in each scanner channel. This minimizes inconsistency in measured values between channels for more accurate measurements throughout the scanner system.
