Chapter 4, Description of Fields
Fields
Failed (annunciator)
This annunciator is lit when an FER test has failed. An FER test fails when the
measured FER is greater than the target FER with the specified confidence level,
according to the criteria established by the confidence level and FER
specification.
Example “Failed” FER measurement
FER Spec
set to 1%
Confidence set to 95%
Measured
FER is displayed as 1.4%
With the parameters specified above,
Failed means that the measured value of
1.4% indicates a true FER of greater than 1% with a confidence level of 95%.
GPIB Example
“DISP CRXT;STATus:CDMA:CONDition?“
queries the CDMA condition register. If bit 9 is set (a decimal value of 512), the
failed condition is true.
Max Frames (annunciator)
This annunciator is lit when an FER test terminates by reaching the number of
frames entered for maximum frames to test. In this case, the measured FER
neither passed nor failed the FER specification with the specified confidence level
within the number of frames entered into the
Max Frames field.
GPIB Example
“DISP CRXT;STATus:CDMA:CONDition?“
queries the CDMA condition register. If bit 8 is set (a decimal value of 256), the
maximum frames condition is true.
