:POD Commands
:POD<n>:THReshold
Command Syntax
:POD<n>:THReshold <type>[<suffix>]
<n> ::= An integer, 1, is attached as a suffix to the command and
<type> ::= {CMOS | ECL | TTL | <user defined value>}
<user defined value> ::= -8.00 to +8.00 in NR3 format
<suffix> ::= {V | mV | uV}
POD1 ::= D0-D7
TTL ::= 1.4V
CMOS ::= 2.5V
ECL ::= -1.3V
The :POD<n>:THReshold command sets the threshold for the specified
group of channels. The threshold is used for triggering purposes and for
displaying the digital data as high (above the threshold) or low (below the
threshold).
This command is only valid for the MSO models.
N O T E
Query Syntax
:POD<n>:THReshold?
The :POD<n>:THReshold? query returns the threshold value for the
specified group of channels.
Return Format
<threshold><NL>
<threshold> ::= Floating point number in NR3 format

' THRESHOLD - This command is used to set the voltage threshold for
' the waveforms. There are three preset values (TTL, CMOS, and ECL)
' and you can also set a user-defined threshold value between
' -8.0 volts and +8.0 volts.
'
' In this example, we set channels 0-7 to CMOS, and then set the
' external trigger to TTL.
' thresholds for the channels you will be using in your program.
' Set channels 0-7 to CMOS threshold.
