Reference Waveform
Data from analog channels or math can be saved to the reference locations (REFA/REFB/REFC/REFD) in the built-in
non-volatile memory. The saved reference waveform can be recalled to be compared with the current waveform.
14.1
Save REF Waveform to Internal Memory
TO save the REDF waveform to internal memory:
1.
Press the REF button on the front to enter the REF WAVE function menu or touch
in the descriptor box region
and select Ref to recall the ref dialog box
When the time horizontal format is in X-Y mode, REF function cannot be enabled.
2.
Touch
Location
; then select the location in which to save the REF waveform.
3.
Touch
Source
; then, select the source of reference channel. The source includes analog channel and math waveforms.
4.
Touch the
Save
icon to save the channel or math waveform to the appointed location.
–
The vertical scale information and the vertical offset of the waveform will be saved at the same time.
–
It will pop out the message
“Save
to internal file
REF”
when the waveform has been saved successfully.
REF waveforms are non-volatile. The REF waveform can still be recalled after restarts or default operation.
14.2
Display REF Waveforms
To display a REF waveform:
1.
Press the REF button on the front to enter the REF WAVE function menu or touch
in the descriptor box region
and select Ref to recall the ref dialog box
2.
Touch
Location
; then select the location of the waveform to be recalled.
3.
Touch
Display
to toggle the waveform on or off. (See figure
Set the vertical position of the reference waveform by the offset knob shared by Decode, Digital, Math, and
Ref on the front panel, and set the vertical scale of the reference waveform by the scale knob.
