Error Description [description/explanation/examples]

 

 

5049

desc = “Wrong marker X axis units for active trace”

 

help = “The active marker cannot be placed on the active trace because the

 

desired X axis units do not match the X axis units of the active trace. This is

 

normally caused by recalling a wavelength trace in zero span or a zero span

 

trace in a wavelength span. It can also be caused by loading a trace with

 

conflicting units by remote control.”

5050

desc = “Trace not displayed: wrong X axis units”

 

help = “View has been turned on for this trace but it cannot be displayed. The X

 

axis units in the trace do not match the X axis units being displayed. This is

 

normally caused by trying to view a wavelength trace in zero span or a zero span

 

trace in a wavelength span. It can also be caused by loading a trace with

 

conflicting units by remote control.”

5051

desc = “AutoMeasure cannot find input signal at marker”

 

help = “The auto-measure function was requested. The auto-measure at marker

 

option was enabled but the active marker was not placed on a valid signal. A

 

valid signal was found but the active marker is too far from that signal. To

 

correct this problem place the marker on the desired signal turn off all markers

 

or disable the auto-measure at marker function.”

5052

desc = “Sweep time auto is not allowed in zero span”

 

help = “The sweep time function was requested to switch from manual to auto

 

while in zero span. Automatic sweep time coupling cannot be done in zero span.

 

The desired sweep time must be set explicitly.”

5053

desc = “Noise marker not allowed.”

 

help = “A request was made to enable the noise marker readout. The readout

 

cannot be enabled for one of the following reasons. Noise markers cannot be

 

used on traces which have X axis units other than meters. This typically occurs

 

in zero span where the X axis units are seconds. Noise markers cannot be used

 

on traces which have Y axis units other than power. This typically happens when

 

trace math is on and the trace Y axis represents a ratio.”

5054

desc = “Bandwidth markers are not allowed in zero span”

 

help = “A request was made to enable the bandwidth marker readout while the

 

OSA was in zero span. Bandwidth markers are not permitted when span is set to

 

zero. If a bandwidth marker readout is required set span to a value greater than

 

zero.”
