The module NetworkAnalyzuer is used to retrieve S-parameters from PNA or VNA instruments. At each measurement point created in the sequencer, a full frequency scan of S-parameters is returned by the driver. The module is not part of the standard installation of SweepMe! and can be downloaded if needed using the [Version manager].

User interface

Device

Select the driver.

Port

Select the communication port. Use 'Find ports' to refresh the list of ports.

Key: "Port"

Calibration

Select the calibration. Use 'Find calibrations' to refresh the list of calibrations. Which calibrations are presented depends on the driver and you can find further details in the description of the driver. In general, all calibration files must be saved to the public SweepMe! folder "CalibrationFiles".

Key: "Calibration"

Terminals

Select the measurement ports that are connected to the device under test, e.g. "1,2" to retrieve S11, S12, S21, and S22. You can also use "1,3,4" to retrieve all 9 S-parameters between these ports or "1,2,3,4" to get all 16 S-parameters. If your instrument only has two ports, you can only use "1,2" or one of the two ports.

Key: "Terminals"

Average

Insert over how many numbers the measurement should be averaged.

Key: "Average"

Source power

Select the source power in dbm. This value is applied to all ports.

Key: "SourcePower"

Source attenuation

Select the source attenuation in dB. This value is applied to all ports.

Key: "SourceAttenuation"

IF bandwidth

Select the IF bandwithh in Hz

Key: "IFBandwidth"

Correction

Switch the correction on or off.

Key: Correction

Trigger

Select whether an internal or external trigger is used and whether a trigger delay should be used.

Key: "Trigger"
Key: "TriggerDelay"

Frequency range

Define the list of frequency. Insert a start and end freuqency. Depending on the driver you can have different options to create linearly or logarithmicly spaced frequencies. For compatibility between all drivers, the options should be "Linear (points)", "Linear (steps in Hz)", and "Logarithmic (points)".

Key: "FrequencyStart"
Key: "FrequencyEnd"
Key: "FrequencyStepPointsType"
Key: "FrequencyStepPoints"

Display

Select whether the display is switched on or off. This can increase the measurement speed as no plots are updated if the display is switched off.

Key: "Display"
