This command replaces SENS:CORR:CSET:CAT?

(Read-only) Returns the names of Cal Sets stored on the VNA.

Parameters

None

Examples

CSET:CAT?

Returns:

"CalSet_0913,CalSet_1,CalSet_2,CalSet_3,CalSet_4,CH1_CALREG,CH31_CALR

EG,MyCalAll_SMC_002,MyCalAll_STD_001"

Return Type

Comma-separated string of names

Default

Not Applicable

(Write-only) Deletes ALL Cal Sets from the VNA, including phase reference and Global Delta Match Cal Sets.

Parameters

None

Default

This command replaces SENS:CORR:CSET:DELete

(Write-only) Deletes the specified Cal Set from the VNA.

• If the Cal Set is currently being used by a channel, the Cal Set is deleted and correction for the channel is turned off.

• If the Cal Set is not found, no error is returned.

Parameters

<string>

Name of the Cal Set to delete. Not case-sensitive.

Examples

CSET:DEL "MyCalSet"

Query Syntax

Not Applicable

Default

Not Applicable

(Read-only) Returns whether or not the specified Cal Set exists on the VNA.

Parameters

<string>

Name or GUID of the Cal Set enclosed in quotes.

The GUID must also be enclosed in curly brackets.

Examples

dim check

check = CSET:EXISts? "MyCalSet"

check = CSET:EXISts? "{7C4EEA5E-40D2-4D70-A048-33BFFE704163}"

Return Type

Boolean

ON or 1 - Cal Set exists.

OFF or 0 - Cal Set does NOT exist.

Default

Not Applicable

(Write-only) 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 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.

Parameters

<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>

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

<compPwr>

(Boolean)

ON (1) - 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.

OFF (0) - Do not compensate for loss in source power through the fixture.

[extrap]

(Boolean) Optional argument.

ON (1) -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.

OFF (0) - Extrapolation is NOT performed (default setting).

Examples

CSET:FIXT:DEEM "MyCalSet","MyNewCalSet","Fixture.s2p",1,1

cset:fixture:deembed "MyCalSet","MyNewCalSet","Fixture.s2p",1,1,1 'extrapolation is performed if the s2p frequency range is narrower than that of the Cal Set.

Not Applicable

Default

Not Applicable

(Write-only) Embeds a fixture (usually a matching network) into an existing Cal Set based on an S2P file. A new Cal Set is created with the effects of the matching network included in the correction data.

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

Parameters

<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 embedded.

<s2p>

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

<port>

(Numeric) Port number to which fixture will be added.

<compPwr>

(Boolean)

ON (1) - Increase the source power to compensate for the loss through the fixture. The result is that the specified power level will be correct at the DUT input.

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

OFF (0) - Do not compensate for loss in source power through the matching network.

[extrap]

(Boolean) Optional argument.

ON (1) -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.

OFF (0) - Extrapolation is NOT performed (default setting).

Examples

CSET:FIXT:EMB "MyCalSet","MyNewCalSet","Fixture.s2p",1,1

cset:fixture:embed "MyCalSet","MyNewCalSet","Fixture.s2p",1,1,1 'extrapolation is performed if the s2p frequency range is narrower than that of the Cal Set.
