Understanding Parameter Displays
The Parameter Display Format
Understanding the information in the parameter displays is easy. The following
table explains what each abbreviation means, following the parameter display
from left to right, and top to bottom.
The format is Px:Name(source) with value and status contained as follows:
P1, P2, P3,
The number of the parameter measurement. P means Parameter.
P4, P5, P6
Each parameter is uniquely identified.
Name
In the example in step 3 (above), max is the parameter name, short
for maximum. A brief definition of each parameter is included in the
measurement selection dialog box.
(source)
The source can be a channel (Cx), a zoom trace (Zx), a math trace
(Math), or a memory (reference waveform) (Mx)
value
The last measured value in the acquisition.
status
An indication of whether the parameter was calculated correctly. A
Reference the following table for information on other status
symbols.
Status Symbols
Below each parameter appears a symbol that indicates the status of the
parameter, as follows:
A green check mark means the oscilloscope is returning a valid value.
A crossed-out pulse means the oscilloscope is unable to determine top and
base. However, the measurement could still be valid.
A downward pointing arrow indicates an underflow condition (signal below
the grid area).
An upward pointing arrow indicates an overflow condition (signal above the
grid area).
An upward-and-downward pointing arrow indicates an underflow and
overflow condition (signal below and above the grid area).
