Technical data

Creates a Fast Eye Mask measurement object. The return value is the handle used
to identify this object by any calls to this object. If, for example, 2 is returned, typical
calls to this object would be:
• :MEAS:GEN2:GO
• :MEAS:FEM2:PASSed?
MEAS:FEMask(*):PARameter:MCBits[?]
IAgilentN490xEDFastEye.ComparedBits
MEAS:FEMask(*):PARameter:MCBits <num>
MEAS:FEMask(*):PARameter:MCBits?
After this number of compared bits, the measurement stops for the current sample
point and moves to the next one.
The default is 1 million bits. That means, you can measure a bit error rate as low
as 10
^-6
(one error per million).
A smaller number reduces the duration of the whole Fast Eye Mask measurement.
A larger number increases the precision of the measured bit error rates.
Note that the measurement moves to the next point when either the number of
errors or the number of measured bits is reached.
The query returns the setting, not the number of bits actually measured.
MEAS:FEMask(*):PARameter:MERRor[:VALue][?]
IAgilentN490xEDFastEye.ComparedErrors
MEAS:FEMask(*):PARameter:MERRor[:VALue]<num>
MEAS:FEMask(*):PARameter:MERRor[:VALue]?
After this number of errors, the measurement stops for the current sample point
and moves to the next one. This allows you to speed up the measurement. You
can switch off this option if only the number of compared bits is important.
This parameter is only evaluated when error mode is enabled (see following
command).
Note that the measurement moves to the next point when either the number of
errors or the number of measured bits is reached.
