:TRIGger:ADVanced:PATTern:THReshold:POD<N>
Command :TRIGger:ADVanced:PATTern:THReshold:POD<N> {CMOS50 | CMOS30 | CMOS25
| ECL | PECL | TTL | <value>}
The TRIGger:ADVanced:PATTern:THReshold:POD<N> command sets the
logic threshold value for the selected pod. POD1 is digital channels D0
through D7 and POD2 is digital channels D8 through D15. 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, 1-2.
<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 voltages less than the threshold are 0 logic
levels.
Query
:TRIGger:ADVanced:PATTern:THREShold:POD<N>?
The :TRIGger:ADVanced:PATTern:THReshold:POD<N>? query returns the
threshold value for the specified pod.
