For each acquired sample, the instrument compares the input voltage with the threshold
value. If the input voltage is above the threshold, the signal state "1" is stored. Otherwise,
the signal state "0" is stored if the input voltage is below the threshold.
Remote command:
DIGital<m>:THReshold on page 435
Technology ← Threshold
Selects the threshold voltage for various types of integrated circuits from a list. The value
is applied to the selected nibble, or to all digital channels if "Couple Levels" is enabled.
Remote command:
DIGital<m>:TECHnology on page 435
Hysteresis ← Threshold
Hysteresis avoids the change of signal states due to noise oscillation around the thresh-
old level. Set a small hysteresis for clean signals, and large hysteresis for noisy signals.

Remote command:
DIGital<m>:Hysteresis on page 436
Couple Levels ← Threshold
Applies the threshold and hysteresis values of the first nibble (D0 to D3) to all digital
channels.

Label
Opens the "Label" menu.
You can define a label for each digital channel, and display each label individually. The
labels are shown on the the right side of the display. You can enter a label text in several
ways:
●
Select a predefined string from the "Library".
●
Enter a user-defined text using "Edit Label".
Remote command:
DIGital<m>:LABel on page 436
Bit ← Label
Selects the digital channel for which the label is to be defined.
