Error Messages
INVALID OUTPUT FORMAT
The output format is not valid. See the
appropriate programming command description to determine the
correct format. (U)
INVALID RANGE: Stop < Start
Indicates that the first trace
element specified for a range of trace elements is larger than the
ending trace element. When specifying a trace range the starting
element must be less than the ending element. For example,
TRA[2,300] is legal but TRA[300,2] is not. (U)
INVALID RS-232/OPERATION
An RS-232 operation was aborted
due to an invalid operation. (U)
INVALID START INDEX
Indicates that the first trace element
specified for a range of trace elements is not within the trace range
of the specified trace. (U)
INVALID STOP INDEX
Indicates that the ending trace element
specified for a range of trace elements is not within the trace range
of the specified trace. (U)
INVALID STORE DEST: _ _ _
The specified destination field is
invalid. (U)
INVALID TRACE: _ _ _
The specified trace is invalid. (U)
INVALID VALUE PARAMETER: _ _ _
The specified value
parameter is invalid. (U)
Marker Count Reduce SPAN
Indicates the resolution bandwidth
to span ratio is too small to use the frequency count function. Check
the span and resolution bandwidth settings. The acceptable
Span/Res BW ratio is
≤
500. (U)
Marker Count Widen Res BW
Indicates that the current
resolution bandwidth setting is too narrow to use with the marker
counter function. (U)
Meas uncal
The measurement is uncalibrated. Check the sweep
time, span, and bandwidth settings, or press
AUTO COUPLE
. (U)
No points defined
Indicates the specified limit line or amplitude
correction function cannot be performed because no limit line
segments or amplitude correction factors have been defined. (U)
Overload: Reduce Signal
A signal has been applied to the input
connector that caused the overload protection circuitry to engage.
The input signal must be reduced. After the signal is reduced, press
Esc. The change in the instrument’s amplitude state will disengage
the overload protection function. Overload protection engages under
the following conditions: (U) or (M)
