The :SENSe{1-16}:CORRection:COLLect:LRL:SINGleton subsystem commands provide configuration control of the Line-Reflect-Line calibration using singletons in different configurations. The commands provide control of singleton configuration parameters and output reporting. The use of the :LRL:SINGleton commands require a 4-port VNA instrument.
LRL Calibration Subsystems
The LRL-related calibration commands are organized into subsystems in the following sections:
This command loads an LRL cal kit file into the Singleton LRL/TRL calibration on the indicated channel.
Cmd Parameters
<string> Filename and path to the file in the form: 'x:\directory\filename.lcf', where x:\directory\filename.lcf exists and filename.lcf is a valid LRL/TRL cal kit file.
Sets the capacitance of the LRL singleton open on the indicated channel. The C0 (zero) coefficient is measured in Farads. Outputs the capacitance of the LRL singleton open on the indicated channel.
Sets the C1 (C one) coefficient of the LRL singleton open on the indicated channel. The C1 coefficient is measured in Farads/Hertz. Outputs the C1 coefficient of the LRL singleton open on the indicated channel.
Sets the C2 coefficient of the LRL singleton open on the indicated channel. The C2 coefficient is measured in Farads/Hertz^2. Outputs the C2 coefficient of the LRL singleton open on the indicated channel.
Cmd Parameters
<NRf> The input parameter is in Farads/Hertz^2 (Farads per Hertz squared).
Sets the C3 coefficient of the LRL singleton open on the indicated channel. The C3 coefficient is measured in Farads/Hertz^3. Outputs the C3 coefficient of the LRL singleton open on the indicated channel.
Cmd Parameters
<NRf> The input parameter is in Farads/Hertz^3 (Farads per Hertz cubed).
On 4-port VNAs, sets the electrical offset length of the LRL singleton open on the indicated channel for a three-port LRL calibration. A prior command defined the singleton as open or short. This command then defines open/short nature of that singleton. For port-pair and singleton LRL calibrations, the following combinations are allowed:
• Port Pair 1-2 may not be used.
• Port Pair 1-3 with singleton 2 or 4
• Port Pair 1-4 with singleton 2 or 3
• Port Pair 2-3 with singleton 1 or 2
• Port Pair 2-4 with singleton 1 or 3
• Port Pair 3-4 may not be used.
The query outputs the electrical offset length of the LRL singleton open on the indicated channel.
Sets the inductance of the LRL singleton short on the indicated channel. The L0 (zero) coefficient is measured in Henrys. Outputs the inductance of the LRL singleton short on the indicated channel.
Sets the L1 (L one) coefficient of the LRL singleton short on the indicated channel. The L1 coefficient is measured in Henrys/Hertz. Outputs the L1 coefficient of the LRL singleton short on the indicated channel.
Sets the L2 coefficient of the LRL singleton short on the indicated channel. The L2 coefficient is measured in Henrys/Hertz^2. Outputs the L2 coefficient of the LRL singleton short on the indicated channel.
Cmd Parameters
<NRf> The input parameter is in Henrys/Hertz^2 (Henrys per Hertz squared).
The command sets the L3 coefficient of the LRL singleton short on the indicated channel. The L3 coefficient is measured in Henrys/Hertz^3. The query outputs the L3 coefficient of the LRL singleton short on the indicated channel.
Cmd Parameters
<NRf> The input parameter is in Henrys/Hertz^3 (Henrys per Hertz cubed).
The command sets the offset length of the LRL singleton short on the indicated channel. The query outputs the offset length of the LRL singleton short on the indicated channel.
