With instruments that use SCPI, there is usually a query associated with each command. For a simple example, if you had a 34401 DMM and the command to set volts DC function was :CONF:VOLT:DC, if you sent the :CONF? query, the instrument would respond with VOLT DC. I have not used the 4395 and I have not looked in the manual to what is there. If the queries are present, you can run them one at a time. Some of the current settings will determine which, if any, other queries you have to do. Using the DMM example again, if you had a 34401 DMM and you got a function of Frequency back, you would not query range or resolution. Another option is to record what you have sent to the instrument with your program.
If there is a high level command that returns all settings with a single query, then you will find it in the programming manual. Have you gone through that to see if any such command exists?
By tif, I'm assuming you want a screen shot. You could save the front panel image of the graph that is displaying the data. Otherwise, you will have to find the command in the manual that does a screen shot and then the command that will transfer that over the GPIB bus. There have been several posts on instrument screen shots that you might look at but every instrument will implement this functionality a bit differently, if it even implements it at all.
