Keep rotating the Entry Knob until you select the channel you want,then stop . The channel select screen will go away after a few seconds.
- The Second Soft Key is used to select or unselect D7 Thru D0 channels instead of individually selecting and unselecting the channels.
- The Third Soft Key is used to scale the channels.By pressing the Third Soft Key you will notice that the channels are compressed closer together. This feature comes in handy if you want to display more channels on the screen.
- By default the mixed signal scope is setup to display eight channels. To display more then 8 channels do the following.
- using the Third Soft Key select the middle scale setting.
- using the channel select Knob select D0.
- using the D15-D0 Knob move D0 to the top of screen. Continue doing this for all the other channels so that D0 Thru D7 are all in the top half of the screen.
- Press the D15 Thru D8 key. This will give you 16 channels.
- *NOTE* You cannot display 16 channels in full scale. Only 8 channels can be displayed in full scale.

You will notice that value appear in the New Label = window.
- The Third Soft Key is also used to select all the characters in the new label = window. By continually pressing the Third Soft Key you scroll through all the characters in the New Label = window.
- The Fourth Soft Key deletes the hi-lighted character.
- The Fifth Soft Key saves the New label = window to the Save Label = window. This then becomes the new name for the selected channel at the First Soft Key.
- The Sixth Soft Key is a library of saved label names. This can be advantageous since it allows you to select names from an accumulated list rather then have to spell them.
If the Label Key is lit Green then the label names should appear beside the channels. Press the Label Key till the Green light is off. You will notice that the label names disappear. When the Label Key is lit Green it should look similar Figure 1. It is possible that the label names may be different then below depending on whether someone has already renamed the labels.

How to RENAME each CHANNEL

Select the Label Key in the Digital Channel Inputs/Controls menu.
Select the First Soft Key Channel
Turn the Entry Knob. Turning the Entry Knob scrolls through the channels. Stop at the channel you want to edit the label name.
Select the Second Soft Key Spell .
Turn the Entry Knob. Turning the Entry Knob scrolls through the letters,numbers or symbols in the Character window.
Stop at the letter,number or Symbol you want.
Press Third Soft Key Enter
The letter,number or symbol appears in the New Label = window.
By continually pressing Third Soft Key you select all the characters in the New Label = window.
Once the label name is edited press the Fifth Soft Key. This will save the label name to the Saved Label = window.
This will also become the name of the channel that was selected by the First Soft Key .
To change other channel names follow the steps just described.

Examples of Assigning Label Names

PREDEFINED NAME (R/W_ on Channel D5):

Press the Label Key .
Press the First Soft Key, then use the Entry Knob to select Channel D5
Press the Sixth Soft Key Library .
Turn the Entry Knob until R/W_ appears in the New Label = Window, then stop. The library window will disappear in a few seconds.
Press the Fifth Soft KEY Save New Label. The label name R/W_ will now appear in the Saved Label = window.
Now Channel D5 has the new label name R/W_.

UNIQUE NAME (BRL on Channel D4):

Press the First Soft Key, then use the Entry Knob to select Channel D4
Press Second Soft Key Spell.
Using the Entry Knob rotate until B appears in the New Label = window.
Press the Third Soft Key Enter. The prompt in the New label = window will move over one position.
Repeat the above two steps for the letters RL.
Use the Fourth Soft Key Delete Character to get rid of any unwanted characters.
Press the Fifth Soft KEY Save Label Name
The label name BRL will appear in the Saved Label = window.
Now Channel D4 has the new label name BRL.
Continue to use this technique to rename any of the channel Label Names

Setting up a trigger Value

Press the Pattern Key in the Trigger menu.
Another set of Soft Key Menus will appear.
- Press the First Soft Key Channel, then use the Entry Knob to select a channel.
  The channel label name appears in the Channel window.

- Third Soft Key selects active high trigger event.
- Fourth Soft Key selects done care.
- Fifth Soft Key selects active rising edge trigger event.
- Sixth Soft Key selects active falling edge trigger event.
Above the Pattern Select there is an expression;

Pattern = 1xx2 D15xxxx xxxx xxxx xxxx D0
- 1xx2 represent the trigger setting for Analog Channels 1 and 2.
  For most of the applications in the lab we ignore analog triggering so leave these two channels as Don't Care "X".
- D15xxxx xxxx xxxx xxxxD0 represent each of the digital channels D0 - D15.
- Scroll through the digital channels using the Entry Knob
  The channel beside the check mark can be changed to any of the trigger values;
  [ L,H,Rising Edge,Falling Edge ]

Example of setting up a Trigger event

For this example do the following:
Change the channel label names as shown below;

	0 Bit0 -------> CLK
	1 Bit0 -------> DTACK
	2 Bit0 -------> AS
	3 Bit0 -------> UDS
	4 Bit0 -------> LDS
	5 Bit0 -------> R/W
	6 Bit0 -------> A23
	7 Bit0 -------> A22
