Command
:DIGital<N>:THReshold {CMOS50 | CMOS30 | CMOS25 |
ECL | PECL | TTL | <value>}
The :DIGital<N>:THReshold command sets the logic threshold value for a pod.
Setting the threshold for digital channels 0 through 7 sets the threshold for pod
1 while setting the threshold for digital channels 8 through 15 sets the threshold
for pod 2. This command is equivalent to the POD<N>:THReshold command.
The threshold is used for triggering purposes and for displaying the digital data
as high (above the threshold) or low (below the threshold). The voltage values
for the predefined thresholds are:
CMOS50=2.5 V
CMOS30=1.65 V
CMOS25=1.25 V
ECL=-1.3 V
PECL=3.7 V
TTL=1.4 V
<N>
An integer, 0 - 15.
<value>
A real number representing the voltage value which distinguishes a 1 logic level
from a 0 logic level. Waveform voltages greater than the threshold are 1 logic
levels while waveform vlotages less than the threshold are 0 logic levels. The
range of the threshold voltage is from -8 volts to 8 volts.
Example
This example sets the threshold to 5 volts for bits D15 through D8.

The DIGital commands only apply to the MSO Oscilloscopes.
