About Cal Sets

Description

De-embeds a fixture from an existing Cal Set based on an S2P file. A new Cal Set is created with the effects of the fixture removed.

When the new Cal Set is applied to a channel, the effects of the fixturing are removed from the measurement data. Do NOT enable  fixturing. The effects of the fixture are removed when the new Cal Set is selected and correction is turned ON.

 VB Syntax

calMgr.Deembed (cs1,cs2,s2p,port, compPwr,extrap)

Variable

(Type) - Description

calMgr

(object) - A CalManager object

cs1

(String)  Name of an existing Cal Set which resides on the VNA.

cs2

(String)  Name of new Cal Set which contains updated error terms with fixture de-embedded.

s2p

(String) Name of the S2P file which characterizes the adapter/fixture.

port

(Long Integer) Port number from which fixture will be de-embedded.

compPwr

(Boolean)

True - When the Cal Set contains a power correction array for the fixture port, that array will be compensated for the fixture loss.  

Warning: enabling power compensation can result in an increase in test port power and consequently, increased power to the DUT. Use with caution.

False - Do not compensate for loss in source power through the fixture.

extrap

(Boolean)

True - Applies a simple extrapolation when the S2P file has a narrower frequency range than the Cal Set. The values for the first and last data points are extended in either direction to cover the frequency range of the Cal Set.

False - Extrapolation is NOT performed (default setting).

Return Type

Not Applicable

Default

Not Applicable
