constant (i.e., be the same material). In the case of LRM calibration, you need to prepare a
match instead of a line standard.
NOTE
Do NOT delete this VBA macro. This VBA macro cannot be recovered even performing
the system recovery once deleted.
NOTE
You can perform LRL calibration using a line standard instead of the thru standard because
this VBA macro lets you define an arbitrary value as the delay of the thru standard. To
perform LRL calibration, define the delay value of the line at the thru definition and then
measure the thru calibration data by using the line standard.
Note on Use
Set the power level to -10 dBm or less in order to accurately measure a DUT close to the
open or short state.
Operating Procedure
1. Setting stimulus conditions
Set the stimulus conditions of the channel for which you perform the calibration.
For information on the setting procedure, see Chapter 3, "Setting Measurement
Conditions."
