TIMEDATE
ON OFF
turns the display of the real-time clock on or off. Pressing DEFAULT CONFIG
sets TIMEDATE ON OFF to ON.
Front-Panel Key Access: C-j
TO1
ON OFF
finds the third-order intercept of the two highest amplitude signals and the two
associated distortion products. The effect of unequal test signal amplitude is
compensated for. The measurement runs continuously, re-executing at the end
of each sweep. The units for the displayed value can be selected by pressing
Amptd Units softkey. The two test signals and the two associated distortion
products must all be displayed for the measurement to function. The relative
amplitudes and frequencies of the displayed signals must fit the TO1 pattern.
All of the signals must be greater than the peak excursion above the threshold.

TRACE
ABC
TRACE A
TRACE B
TRACE C
accesses the trace softkeys that allow you to store and manipulate trace
information. Each trace is comprised of a series of data points that form a
register where amplitude information is stored. The spectrum analyzer updates
the information for any active trace with each sweep. If two traces are
being written to, they are updated on alternating sweeps. (Also see “Screen
Annotation” in Chapter 2.)
selects the softkey menu used for trace A, trace B, or trace C functions. Press
TRACE A B C until the letter of the desired trace is underlined.
Front-Panel Key Access: (Wj
sets up trace A for recalling previously-saved trace data into trace A or saving
trace data from trace A.
Front-Panel Key Access: [ml or LEAVE_)
sets up trace B for recalling previously-saved trace data into trace B or saving
trace data from trace B.
Front-Panel Key Access: (j%Z.Q or ISAVE_)
sets up trace C for recalling previously-saved trace data into trace C or saving
trace data from trace C.
Front-Panel Key Access: (RECALL] or ISAVE_I
