Analog channel or math waveforms can be saved to one of two reference 
waveform locations in the oscilloscope. Then, a reference waveform can be 
displayed and compared against other waveforms. One reference waveform can 
be displayed at a time.
When the multiplexed knobs are assigned to reference waveforms (this happens 
when you press the [Ref] key and the LED to the left of it is lit), you can use the 
knobs to scale and position reference waveforms. There is also a skew adjustment 
for reference waveforms. Reference waveform scale, offset, and skew information 
can optionally be included on the oscilloscope display.
Analog channel, math, or reference waveforms can be saved to a reference 
waveform file on a USB storage device. You can recall a reference waveform file 
from a USB storage device into one of the reference waveform locations.
To save a waveform to a reference waveform location
1 Press the [Ref] key to turn on reference waveforms.
2 In the Reference Waveform Menu, press the Display Ref softkey and turn the 
Entry knob to select the desired reference waveform location you want to
