Single Channel
Correction Mode
When the correction mo de is set to SINGLE, the OPEN/SHORT
interpolation correction data or the FREQ1/FREQ2/FREQ3
correction data are selected automatically, dep ending on the test
frequency and the settings of the OPEN, SHORT, LOAD, FREQ1,
FREQ2 and FREQ3 elds. Table D-1 shows the correction data
selection rules for the SINGLE mo de and corresp onding test
frequencies.
