Key Descriptions
An E appears in the special functions area at the left
side of the display screen when the stimulus response
mode is selected. Manual sweep mode only applies to
SA mode. If SWP TIME AUTO MAN is set to MAN, the
analyzer sweep time coupling defaults to SA mode. The
SWP CPL SR SA softkey is located under the
TRACKING GENRATOR menu.
Front-panel key access:
AUTO COUPLE or SWEEP
THRESHLD ON OFF Sets a threshold that determines the lower limit of
the active traces. To change the threshold, use the data
keys, the step keys, or the knob. The selected level is
indicated by a dashed line across the screen. When the
trace is in max-hold mode, once the threshold is raised,
any data below the new threshold is permanently lost.

TITLE DONE Ends editing of the current title and returns to the
previous softkey menu.
Front-panel key access: DISPLAY
TRACE Accesses a menu of trace-related functions, which are
as follows: CLEAR WRITE A, MAX HOLD A, VIEW A,
BLANK A, TRACE A B, VID AVG ON OFF,
DETECTOR MODES, A EXCH B, NORMLIZE ON
OFF, NORM REF POSN, A−B→A ON OFF, A+B→A,
B−DL→B, and A−B+DL→A ON OFF. Trace A is
brighter than trace B, to distinguish between the two
traces.
Front-panel key access:
TRACE
TRACE 0 through TRACE 7 Allows you to select a trace register to recall
or save trace information.
Front-panel key access: RECALL or SAVE
NOTE SAVE TRACE A and SAVE TRACE B use exactly the same eight save-trace
registers in which to store trace data. Be careful not to overwrite
previously saved trace data.
Trace-registers 5, 6, and 7 should not be used when using an Agilent
85620A mass memory module. These trace registers are used by the
module and may be overwritten if trace data has been previously stored
in them.
TRACE A B Toggles the trace softkey functions between traces A
and B.
Front-panel key access: TRACE
