You can:
●
Select one of the default values for TTL, ECL, or CMOS
–
TTL: 1,4 V
–
ECL: -1,3 V
–
CMOS: 2,5 V
●
Set the "User" value individually
●
Let the instrument analayze the signal and find an appropriate level
The threshold is applied to the selected channel.
Remote command:
Label
Opens the "Label" menu to define an additional name label for the selected waveform.

Probe Menu (Passive Probe)
In the probe menu for passive probes, the probe attenuation for the selected channel is
set. If the probe is known to the instrument, the attenuation factor is set automatically.
For unknown probes, you can select a default factor or enter a user-defined value.
Access: CH N > "More > Probe"
x1, x10, x100, x1000: attenuation factor
The keys select a default attenuation factor of the connected probe. The vertical scaling
and measured values are multiplied by this factor so that the displayed values are equal
to the undivided measured signal values.
To set an arbitrary attenuation factor, press the "User" softkey.
User: user-defined attenuation factor
You can enter an arbitrary attenuation factor in the range between x0.001 and x1000.
The vertical scaling and measured values are multiplied by this factor so that the dis-
played values are equal to the undivided measured signal values.
