Specifies the frequency-dependent loss, Loss2 in dB, to compensate as part of the port extension.

If in addition to the DC loss and frequency-dependent loss at one frequency (Loss1 at the frequency f1), the loss at a second frequency, Loss2 at frequency f2 is also known, the total loss at frequency f can be approximated by:

L (f) = DC Loss + ((Loss1 - DC Loss) x (f / f1)^b)

, where b = log[(abs((Loss1 - DC Loss) / (Loss2 - DC Loss)))] / log(f1 / f2)

This property is used only when you set the Port Extension Enabled property to True, the Port Extension Loss1 Enabled property is set to True and the Port Extension Loss2 Enabled property is set to True. This value is expressed in dB.

Use "port::<portname>" as the selector string to configure or read this property for a specific VNA port. Use "port::all" to configure same value of Loss2 for all VNA ports.

The default value is 0 dB.
