Multi Channel
Correction Mode
To use the multi channel correction mo de, Option 301 Scanner
Interface must be installed, and the scanner interface function
should b e set to ON from the SYSTEM CONFIG page. When the
correction mo de is set to MULTI, only FREQ1/FREQ2/FREQ3
correction data is used for correction. If the settings of the FREQ1,
FREQ2 and FREQ3 elds are OFF (even the OPEN, SHORT and
LOAD elds are ON), correction will not b e p erformed. Table D-2
shows the correction data selection rules for MULTI mo de and
corresp onding test frequencies.
