Calibration Types

Response & Isolation This is a very limited calibration, which corrects only for frequency response

and isolation, not for directivity or source match errors. The performance of

the 8510XF is not speciﬁed, if this calibration is used. To perform this

calibration using the 1.0 mm calibration kit, select:

[CAL] {CAL1 or CAL2} {RESPONSE & ISOL’N}

This will call up the menu and submenu shown below:
