Figure 7-7. Sweeper Display and LED Annunciators
The front panel annunciators show the status of several of the sweeper
functions and settings. Refer to Figure 7-7. Notice that there are two types of
annunciators: display and LED.
A display annunciator is not visible if its associated function is not active or
selected.
For example, if external pulse modulation is currently selected, the
EXTMOD annunciator will be lit, otherwise, it will not be visible.
The display annunciators that will appear in the left-hand (frequency)
display are SHIFT, START, CF, CW, MAN, SWEEP, EXT REF, ALT, STOP,
SPAN, MULT, and OFFSET. The display annunciators that will appear in
the right-hand (marker/sweep/status and power) display are MSG, MKRS,
EXTMOD, INTMOD, UNLOCK, STEP, UNCPLD, EXT ALC, PWR SWP,
SLOPE, UNLEV, and RF OFF.
