Site Masterâ„¢ S331P : File Management : Save File : File Name
 
File Name
In the Filename edit box, you can either use the default name or enter a custom name. The default name is based on the instrument model, current display format and measurement type, and a sequence number. For example:
S331P 1x [RL] #5, where:
1x = Single display
2x = Dual display
RL = Return Loss
DTF-RL = Distance to Fault Return Loss
CL = Cable Loss
VSWR = Voltage Standing Wave Ratio
DTF-VSWR = Distance to Fault Voltage Standing Wave Ratio
SC = Smith Chart
PH = 1-Port Phase
The file sequence number (#n) is automatically incremented each time a file of the same type is saved.
Note 
The file extension is determined by the type of file being saved: measurement (.dat), setup (.stp), screen shot (.png), text (.txt), or CSV (.csv).
To enter a custom file name, simply type over the default name. Optionally, you can use the EZ Name keyboards to quickly enter character strings that make up a custom file name.
EZ Name Keyboards
Some carriers may require files to be named according to specific conventions, including site ID, color coding, measurement type, termination device, and frequency information.
Press one of the two EZ Name Page Selection keys to display the EZ Name keyboard, then touch an EZ Name key to enter the corresponding preset character string in the Filename edit box.
EZ Name Keyboards
The Separator keys determine whether to automatically insert a separating character (hyphen or underscore) after each name string entered by pressing an EZ Name key.
EZ Name Keys
Pressing an EZ Name key inserts the associated character string into the name of the file being saved. To define your own EZ Name keys or rename an existing key:
1. Press Rename Keys on the appropriate EZ Name keyboard (Page 1 or Page 2). See Figure: EZ Name Keyboards.
2. Press the EZ Name key you want to define or rename.
3. Enter a new name, e.g., GREEN, for the selected key.
Renaming an EZ Name Key
4. Press Done to apply the character string to the EZ Name key. The EZ Name keyboard now shows the key with its new name. In the example, one of the Color Code keys was renamed.
