is used to enter the standard numbers for the third class required for an SZZ l-port calibration. (For default kits, this is the load.)

measures the short circuit TRL/LRM calibration data for PORT 2.

selects whether sampler correction is on or off.

saves the modified version of the color set.

provides access to all the menus used for saving and recalling instrument states in internal memory and for storing to, or loading from, external disk. This includes the menus used to dellne titles for internal registers and external disk flies, to define the content of disk files, to initialize disks for storage, and to clear data from the registers or purge files from disk.

stores the user-modified or user-deilned kit into memory, after it has been modified.

selects ASCII format for data storage to disk.

selects binary format for data storage.

changes the response value scale per division of the displayed trace. In polar and Smith chart formats, this refers to the full scale value at the outer circumference, and is identical to reference value.

toggles between two selections for plot scale, FULL and GRAT.

is the normal scale selection for plotting on blank paper. It includes space for all display annotations such as marker values, stimulus values, etc. The entire display Ills within the user-defined boundaries of Pl and P2 on the plotter, while maintaining the exact same aspect ratio as the display.

expands or reduces the horizontal and vertical scale so that the lower left and upper right graticule comers exactly correspond to the user-de&red Pl and P2 scaling points on the plotter. This is convenient for plotting on preprinted rectangular or polar forms (for example, on a Smith Chart).

makes scale per division the active function. A menu is displayed that is used to modify the vertical axis scale and the reference line value and position. In addition this menu provides electrical delay offset capabilities for adding or subtracting linear phase to maintain phase linearity.

searches the trace for the next occurrence of the target value to the left.

searches the trace for the next occurrence of the target value to the right.

moves the active marker to the maximum point on the trace.

moves the active marker to the minimum point on the trace.

turns off the marker search function.
