Reference Waveform
The oscilloscope can save analog channel or math waveforms to the reference waveform locations in the oscilloscope.
Then, a reference waveform can be displayed and compared against other waveforms. All reference waveforms can be
displayed at a time.
8.1 Save REF Waveform to Internal Memory
Do the following steps to save the REF waveform to internal memory:
1. Press the
REF
button on the front to enter the REF WAVE function menu. Note that when the time horizontal
format is in X-Y mode, REF function cannot be enabled.
2. Press the
Source
softkey; then, turn the
Universal Knob
to select the source of reference channel. The source
includes analog channel and math waveforms.
3. Press the
Location
softkey; then, turn the
Universal Knob
to select the position to save the REF waveform. The
source includes analog channel and math waveforms.
4. Press the
Save
softkey 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
“Store Data
Success”
when the waveform has been saved successfully.
Note:
The REF waveforms are non-volatile. The REF waveform can still be saved after restarts or default operation.
8.2 Display REF Waveform
To the following steps to display REF waveform:
1. Press the
REF
button on the front to enter the REF WAVE function menu.
2. Press the
Location
softkey; then, turn the
Universal Knob
to select the REF waveform that you want to display.
3. Press the
Display
softkey to select
On
to display the REF waveform on the screen. Only saved location can be
displayed. The oscilloscope can display all four reference waveforms at a time.
