Step 3. The selections in the next menu to appear, MENU
ACAL, will depend on current instrument conditions,
as follows:
a. THRU UPDATE lets you update the Thru cali-
bration of an active 12-term Calibration. This
updates the transmission frequency response
and load match coefficients.
b. START AUTOCAL lets you start a calibration
using the current setup.
c. CHANGE AUTOCAL SETUP lets you set up a
new calibration, which is what we will do for
this example. This example also assumes that
you have selected the transmission medium and,
if waveguide, identified the cutoff frequency.
