KIT_INFO. “Extension” | The Anritsu Lightning Calibration kit files are supported by the VectorStar MS4640A VNA. The files are usually bundled together on a floppy disk. To use the files, transfer from the floppy disk to a USB memory device. When plugged into an MS4640A Series VNA, the USB drive is identified as drive E:\. Files can be manually loaded by navigating to drive E:\ and selecting the files. The MS4640A VNA Series VNA then loads all of files. Alternatively, use the Lightning LKT command to load all of the calibration kit files. The Lightning calibration kit files all have a base name of “KIT_INFO.Extension” where the extension identifies the connector geometry and gender. | Lightning command: LKT |
LMT | Set up for limit lines. | :MMEMory:STORe:LIMit <string> :MMEMory:LOAD:LIMit <string> |
LOG | A list of all entries in the VectorStar event log. | :MMEM:STORe <string> |
MFT | Multiple Frequency Table configuration file. Default file name is FreqTable.mft (for troubleshooting). | |
PPC | Power sweep power calibration file. | :MMEMory:LOAD:LINearity <string> | :MMEMory:STORe:LINearity{1-2} <string> |
PNG | PNG image of data display area. | :MMEM:STORe <string> | :MMEM:STORe:IMAGe <string> |
PTC | Pretune calibration file. | |
RCVR | Receiver calibration file. | :MMEM:LOAD <string> | :MMEM:STORe <string> |
S1P | Data file in S1P format (see S2P below). | :MMEM:STORe <string> |
S2P | Data file in S2P standard microwave simulator text format. Includes a controlled header and only one or four S-parameters are saved. If an S2P file is requested, but not all of the S-parameters are currently being measured, a value of 0 (zero) is entered for missing parameters. If a full two-port calibration is applied, all of the S-parameters are measured, even if they do not need to be displayed. The resultant S2P file is complete with all S-parameter information. S2P files can be recalled and displayed as trace memory when they are loaded into the active channel. | :MMEM:STORe <string> |

STA | Setup file for all channels. | :MMEM:LOAD <string> | :MMEM:STORe <string> |
STX | Setup file for a single channel. | :MMEM:LOAD <string> | :MMEM:STORe <string> |
TDF | Active trace data memory formatted file. | :MMEMory:LOAD:MDATA <string> |
TDU | Active trace data memory unformatted file. | :MMEMory:LOAD:MDATA <string> |
TMZ | Ten (10) MHz calibration file. Per-system. | :MMEM:LOAD <string> | :MMEM:STORe <string> |
TXT | Active channel trace data text file. Similar to the .csv format described above. A tab-delimited format with an optional descriptive heading in which the data for every trace is saved to a defined location folder. The data for each trace is saved as an X and a Y column to accommodate multiple parameters such as mixed frequency and time domain. Subsequent traces are added as additional columns.The .txt file cannot be recalled into the VNA memory. | :MMEM:STORe <string> |
