Yes, You can save the impedance (R + jX) or admittance (G + jB) data in CSV file format with frequency data.Press Format (hard key - HK) -> SMITH CHART (soft key - SK) .Press Marker Fctn (HK) -> MARKER MODE MENU (SK) -> SMITH MKR MENU (SK) -> a. R+jX MKR to set impedance (R + jX) b. G+jB MKR to set admittance (G + jB)Press Save/Recall (HK) -> SAVE FILE FORMATS (SK) -> FILE TYPE:TEXT (SK) -> SAVE FILE (SK)Note: This function is only available with firmware revision 7.66 and later in 8720 family and 8753 family.
