Couple Levels
Sets all threshold and hysteresis values to the values of the first nibble (D0...D3).
Remote command:
DIGital<m>:THCoupling on page 770
Set all Deskew to Zero
Aligns the skew between the probe boxes of the digital channels and the probe con-
nectors of the analog channels.
Remote command:
DIGital<m>:DESKew on page 771
Technology
Selects the threshold level: 3 predefined threshold levels and user-defined threshold
are available.
"TTL: 1.4V"
Sets the threshold to 1.4 V, which is typically used in transistor–tran-
sistor logic (TTL).
"CMOS: 2.5V"
Sets the threshold to 2.5 V, which is typically used in complementary
metal-oxide–semiconductor technology (CMOS).
"ECL: -1.3V"
Sets the threshold to -1.3 V, which is typically used in emitter-coupled
logic (ECL).
"Threshold"
Selects the user-defined threshold.
Enter the value in Threshold.
Remote command:
DIGital<m>:TECHnology on page 769
Threshold
Sets the threshold level value between -2 V and +8 V in steps of 10 mV, or shows the
value of the selected technology.
Remote command:
DIGital<m>:THReshold on page 770
Hysteresis
Defines the size of the hysteresis to avoid the change of signal states due to noise.
Remote command:
DIGital<m>:HYSTeresis on page 770
Label
Opens a menu to specify user-defined text labels for the individual logic channels.
Bit ← Label
Selects the logic channel or "Bit" for labeling.
●
For the pod "D7...D0", you can select bit "D0", "D1", "D2", ... or "D7".
●
For the pod "D15...D8", you can select bit "D8", "D9", "D10", ... or "D15".
Label ← Label
Enables or disables the user-defined label for the selected logic channel.
