Specifies the frequency-dependent loss, Loss1 in dB, to compensate as part of port extension.

If the DC loss and one additional frequency loss, Loss1 at the frequency F1 is known, the total loss at frequency f can be approximated by:

L (f) = DC Loss + ((Loss1 - DC Loss) x (f / f1)^0.5)

This property is used only when you set the Port Extension Enabled property to True and the Port Extension Loss1 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 Loss1 for all VNA ports.

The default value is 0 dB.
