Specifies the delay of the Thru mechanical standard when Calkit Type property is set to Mechanical and Thru Method property is set to Auto or Undefined Thru. This value is expressed in seconds.

Use this property to specify an approximate delay value of an unknown-thru cal standard. Measurement uses this value to eliminate the uncertainty of ± 180 degrees in the estimated phase response of the Thru.

If you set this property to 0, the VNA automatically determines the delay of the Thru. You only need to set this property to an approximate non-zero delay value when Max Frequency Step Size > 1/(2 x Thru Delay). Here, Frequency Step Size refers to the difference between 2 consecutive frequency points in the set of frequencies sorted in ascending order.

You do not need to use a selector string to configure or read this property for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals.

The default value is 0 s.
