Hardkey and Softkey Reference
SEARCH: TARGET. searches for the user-specified target point on the trace.
SEGMENT. specifies which limit segment in the table is to be modified. A maximum of three sets of segment values are
displayed at one time, and the list can be scrolled up or down to show other segment entries. Use the entry block
controls to move the pointer > to the required segment number. The indicated segment can then be edited or deleted.
If the table of limits is designated “EMPTY,” new segments can be added using the ADD or EDIT softkey.
SEGMENT: CENTER. sets the center frequency of a subsweep in a list frequency sweep.
SEGMENT IF BW. enters the IF bandwidth for the active segment in a swept list table. This key is disabled if is set to
OFF.
SEGMENT POWER. enters absolute power values in the swept list table. The power values are restricted to the current
power range setting. If port power is uncoupled, power applies to the currently selected port, otherwise it applies to
both ports. (The list table only displays one port's power values at time due to limited display area.) To set the
alternate port's power level, you must exit the edit list menus, select a measurement that activates the alternate port,
and then re-enter the edit list menus. This key is disabled if LIST POWER is set to OFF.
SEGMENT: SPAN. sets the frequency or power span of a subsweep about a specified center frequency.
SEGMENT: START. sets the start frequency of a subsweep.
SEGMENT: STOP. sets the stop frequency of a subsweep.
SEL QUAD. leads to the select quadrant menu, which provides the capability of drawing quarter-page plots.
SELECT DEFAULTS. leads to the default menu.
SELECT DISK. provides access to the select disk menu.
SELECT LETTER. The active entry area displays the letters of the alphabet, digits 0 through 9, and mathematical
symbols. To define a title, rotate the knob until the arrow ↑ points at the first letter, then press SELECT LETTER.
Repeat this until the complete title is defined, for a maximum of 50 characters. As each character is selected, it is
appended to the title at the top of the graticule.
Seq. accesses a series of sequencing menus. These allow you to create, modify, and store up to 6 sequences which can
be run automatically.
SEQUENCE 1 SEQ1. activates editing mode for the segment titled "SEQ1" (default title).
SEQUENCE 2 SEQ2. activates editing mode for the segment titled "SEQ2" (default title).
SEQUENCE 3 SEQ3. activates editing mode for the segment titled "SEQ3" (default title).
SEQUENCE 4 SEQ4. activates editing mode for the segment titled "SEQ4" (default title).
SEQUENCE 5 SEQ5. activates editing mode for the segment titled "SEQ5" (default title).
SEQUENCE 6 SEQ6. activates editing mode for the segment titled "SEQ6" (default title).
SEQUENCE FILENAMING. accesses a file naming menu which is used to automatically increment or decrement the name
of a file that is generated by the network analyzer during a SEQUENCE.
SERVICE MENU. leads to a series of service and test menus.
SERVICE MODES. a collection of common modes used for troubleshooting.
SET ADDRESSES. goes to the address menu, which is used to set the GPIB address of the analyzer, and to display and
modify the addresses of peripheral devices in the system, such as the printer, plotter, disk drive, and power meter.
SET CLOCK. allows you to set the analyzer's internal clock.
SET DAY. allows you to set the day in the analyzer's internal clock.
SET HOUR. allows you to set the hour in the analyzer's internal clock.
SET MINUTES. allows you to set the minutes in the analyzer's internal clock.
SET MONTH. allows you to set the month in the analyzer's internal clock.
SET REF: REFLECT. sets the measurement reference plane to the TRL/LRM REFLECT standard.
SET REF: THRU. sets the measurement reference plane to the TRL/LRM THRU standard.
SET YEAR. allows you to set the year in the analyzer's internal clock.
SET Z0. sets the characteristic impedance used by the analyzer in calculating measured impedance with Smith chart
markers and conversion parameters. Characteristic impedance must be set correctly before calibration procedures are
