When you rotate the pan knob clockwise, you
move the RF acquisition time and spectrum
time to the right of the display. When the right
side of the RF acquisition time reaches the
far right side of the screen, you cannot move
RF acquisition time any further to the right.
You can, however, keep moving the spectrum
time further to the right until it reaches the
right side of the RF acquisition time/analog
time.
If you then turn pan counter-clockwise, the
spectrum time goes back to the middle of the
RF acquisition time.
Keep rotating the pan control
counter-clockwise and move the RF
acquisition time and spectrum time together
toward the left of the display. When the
right side of the RF acquisition time reaches
the trigger indicator shown at the top of the
display, you cannot move the RF acquisition
time any further to the left even if you keep
rotating the pan knob. The RF acquisition
time must stay attached to the trigger.
If you keep rotating the pan control
counter-clockwise, the spectrum time will
keep moving left within the RF acquisition
time until it reaches the left end of the RF
acquisition time.
