The Keysight E4980B-301 is the scanner interface option for the E4980B.

When equipped with the Option 301 Scanner Interface, the E4980B supports multi-channel correction. The 14-contact Amphenol connector on the rear panel is used to connect the interface, through which control output signals and multi-channel correction channel selector signals are communicated.

With option 301, it is possible to store and use up to 128 sets of correction data (OPEN, SHORT, and LOAD) for up to 201 user-defined test frequencies. These 128 sets of correction data can be used for each measurement using the multi-channel correction function.

The instrument can correct stray admittance, residual impedance, and other errors for each channel from the calibration plane to the connection contacts at the device. Therefore, option 301 of the can accurately measure impedance values without any degradation of repeatability, or differences between channels. Timing synchronization is also provided.

Please note, this option must be purchased with an instrument. E4980B sold separately.
