Hardkey and Softkey Reference
this is the load.)
S11 REFL SHORT. measures the short circuit TRL/LRM calibration data for PORT 1.
S11/21 ENH. RESP. provides an S11 and S21 enhanced response calibration (forward direction). Enhanced response
generates a 1-port cal for S11 and an improved calibration over the response cal for S21 .
S22 1-PORT. provides a measurement calibration for reflection-only. Measurements of one-port devices or properly
terminated two-port devices, at port 2 of an S-parameter test set.
S22/12 ENH. RESP. provides an S22 and S12 enhanced response calibration (reverse direction). Enhanced response
generates a 1-port cal for S22 and an improved calibration over the response cal for S12 .
S22A. is used to enter the standard numbers for the first class required for an S
22
1-port calibration. (For default cal
kits, this is the open.)
S22B. is used to enter the standard numbers for the second class required for an S
22
1-port calibration. (For default cal
kits, this is the short.)
S22C. is used to enter the standard numbers for the third class required for an S
22
1-port calibration. (For default kits,
this is the load.)
S22 REFL SHORT. measures the short circuit TRL/LRM calibration data for PORT 2.
SAMPLR COR on OFF. selects whether sampler correction is on or off.
SAVE COLORS. saves the modified version of the color set.
SAVE FILE. saves the display information to the disk drive. The type of information saved is dependent on the
FILETYPE selection. The FILETYPE selection can either be graphic or text.
SAVE FILE FORMATS. accesses the save file menu which allows you to save the display information to the disk drive as
either graphic or textual information.
SAVE STATE. saves file data in the next available register if you are saving to internal memory, or saves the data to a
disk.
SAVE USER KIT. stores the user-modified or user-defined kit into memory, after it has been modified.
SAVE USING ASCII. selects ASCII format for data storage to disk.
SAVE USING BINARY. selects binary format for data storage.
Save/Recall. provides access to all the menus used for saving and recalling instrument states in internal memory and
for storing to, or loading from the internal or external disk. This includes the menus used to define titles for internal
registers and external disk files, to define the content of disk files, to initialize disks for storage, and to clear data from
the registers or purge files from disk.
SCALE/DIV. 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.
SCALE PLOT [ ]. toggles between two selections for plot scale, FULL and GRAT.
SCALE PLOT [FULL]. 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 fits within the user-defined boundaries of P1 and P2 on
the plotter, while maintaining the exact same aspect ratio as the display.
SCALE PLOT [GRAT]. expands or reduces the horizontal and vertical scale so that the lower left and upper right graticule
corners exactly correspond to the user-defined P1 and P2 scaling points on the plotter. This is convenient for plotting
on preprinted rectangular or polar forms (for example, on a Smith Chart).
Scale Ref. 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.
SEARCH LEFT. searches the trace for the next occurrence of the target value to the left.
SEARCH RIGHT. searches the trace for the next occurrence of the target value to the right.
SEARCH: MAX. moves the active marker to the maximum point on the trace.
SEARCH: MIN. moves the active marker to the minimum point on the trace.
SEARCH: OFF. turns off the marker search function.
