Obsolete and Discontinued Commands 32
Agilent InfiniiVision 3000 X-Series Oscilloscopes Programmer's Guide 791
:MEASure:LOWer
(see page 860)
Command Syntax
:MEASure:LOWer <voltage>
The :MEASure:LOWer command sets the lower measurement threshold
value. This value and the UPPer value represent absolute values when the
thresholds are ABSolute and percentage when the thresholds are PERCent
as defined by the :MEASure:DEFine THResholds command.
Query Syntax
:MEASure:LOWer?
The :MEASure:LOWer? query returns the current lower threshold level.
Return Format
<voltage><NL>
<voltage> ::= the user-defined lower threshold in volts in NR3 format
See Also • "Introduction to :MEASure Commands" on page 330
• ":MEASure:THResholds" on page 794
• ":MEASure:UPPer" on page 801
NOTE
The :MEASure:LOWer command is obsolete and is provided for backward compatibility to
previous oscilloscopes. Use the :MEASure:DEFine THResholds command (see page 337)
instead.
