Line Sweep Tools allows users to quickly and efficiently process captured line sweeps, as well as PIM measurements. In addition, it has some capability for handling common S parameter measurements as well as transmission measurements. Once setup, they make it possible to apply a set of markers to a trace with one button press. This ensures that markers are where they need to be, every time. Marker presets are invaluable when reviewing large numbers of line sweeps. LST has 7 sets of marker presets.

You can save and recall files to and from an internal or external storage device in a variety of file formats. About Instrument State and Calibration Data. About Measurement Data Files. Save State Softtab help. The selected filename is automatically generate in the storage when you performed a save. Saves state and calibration data to the internal storage in the D: folder.
A filename is generated automatically using the syntax " atxxx "; where xxx is a number that is increment by one when a new file is Auto Saved. The filename is depends on the Save Type to save it in ". Save State As Not available on MxA and EA.
Save Register - Immediately saves the specified register Register 1 to 8 to the selected filename by depends on the Save Type. The selected filename is automatically generate in the storage when you performed a save on selected register. Save Type. State - Save VNA state in. Save Other Softtab help.
Save Calset Save Data Save User Preset Save As dialog box help. Save Allows you to navigate to the directory where you want to save the file. The following file types save Instrument states and Calibration data. You can save, and later recall, instrument settings and calibration data for all channels currently in use on the analyzer. These file types are only recognized by Keysight VNA analyzers. Note: To save the screen as.

Note: Before saving measurement data, always trigger a single measurement, and then allow the channel to go into Hold. This ensures that the entire measurement trace is saved. Save in Allows you to navigate to the directory where you want to save the file. To save the screen as. When correction is ON, saves all corrected parameters associated with the calibrated ports in the Cal Set.
Single Trace - Saves the active trace. Displayed Traces - Saves all displayed traces for all channels. Channel Traces - Saves all displayed traces for active channels. Help - Displays Save Data As dialog box help. Recall State - Select from a list of files shown on softkeys. The list can be sorted by 'most recently used' or alphabetically depending on a preference.
The preference setting appears at the bottom of the second page of softkeys listing files to be recalled or on the Preference dialog.
Recall State Recall Calset Recall Data Recall dialog box help. When an Instrument State file is recalled, the current state of the instrument is overwritten with the recalled state.
Learn more about Instrument States. Click File then Recall. Select Citifile Data or Snp. Note: Filenames not including the path name that are longer than 64 characters will NOT be recalled. The channel is placed in Trigger Hold.
If triggering is resumed, the data will be overwritten. SNP files are recalled as traces into a single window and channel, beginning at the highest available channel number allowed on the analyzer. For multi-port SNP files greater than 4 ports , if the number of S parameters in the file is beyond the maximum number of traces in a window , then new windows will be created.
Citi files are recalled into the same window and channel configuration as when they were saved. However, the new recalled channel numbers begin with the highest channel number allowed on the analyzer and decrement for each additional channel. For example, when a citi file is saved, two traces are in window 1, channel 1 and two additional traces are in window 2, channel 2.
When recalled into a factory preset condition 1 trace in window 1, channel 1 , the first two recalled traces appear in window 2, highest channel number, and the second two traces appear in window 3, highest channel number See also Traces, Channels, and Windows. An Instrument State contains almost every analyzer setting. The following file types are used to save and recall instrument states and Cal Set information:.
Information that is stored for each channel. Instrument State Information. Stimulus Information:. Sweep mode. Cal Set Information. Name, Description, Modify date. The following describes each file type, and what occurs when the file type is recalled.
Instrument states can have the following suffixes:. Common to all of the instrument state files is the state of the instrument including the quantity and content of channels, traces, windows, markers, limit lines, etc. What is different about the instrument state files is the way they handle the calset - a calset is the set of data that results from having executed a calibration on a channel. When recalled, they always replace the current instrument state immediately.
T his instrument state file is saved without any calset data. You might choose to use this type of save file if you are concerned about disk space or specifically do not want to store calibration data that tends to have a shelf life. That is, calibrations become less accurate as cables move and temperature changes.
Perhaps you want to force a new calibration when the instrument state is used. There is no compatibility among the VNA family products. The analyzers cannot recall file saved by that with the smaller number of port. Learn more about Cal Sets. The quickest and most flexible method of saving and recalling a calibrated instrument state. When recalled, the state information is loaded first. Then the analyzer attempts to apply a Cal Set as you would do manually. If the stimulus settings are different between the instrument state and the linked Cal Set, the usual choice is presented see Cal Sets.
If the linked Cal Set has been deleted, a message is displayed, but the state information remains in place. Because only a link to the Cal Set is saved, the Cal Set can be shared with other measurements. Note: Before saving a. Cal Registers are overwritten with new data whenever a calibration is performed, and may not be accurate cal data when the. Apply the calibration data to a channel as you would apply any Cal Set.
The safest method of saving and recalling a calibrated instrument state. Every channel that has an active calibration that is, has a calset selected and applied to the channel stores its calibration data into the. You save a. When this is about to occur, you are given a warning. These files should never be accessed or copied by the user.
Comma-separated data which can be read into rows and columns by spreadsheet software, such as Microsoft Excel. To avoid the "delimiting" dialog boxes, change the filename extension from. Then open directly into Microsoft Excel. Contain formatted and corrected stimulus and response data for the current active trace ONLY. See the Touchstone specification.
Before saving measurement data, always trigger a single measurement, and then allow the channel to go into Hold. Select a different format to save the smoothed data. S2PX files.
