Fber Measurement Results - Agilent Technologies 8960 10 Series Reference Manual

Fast Bit Error Measurement Description
NOTE In case the test set is not able to correlate the data it transmits on the downlink with the data it
receives on the uplink, a Measurement Timeout value should be set. If a timeout is not set and
the test set is unable to correlate, the measurement will appear to "hang".
The FBER, BERR and the DAUDIO (uplink speech level) measurements are mutually exclusive, that is which
ever of these measurements is activated last forces the other to become inactive. see
Measurement Description" on page 55
FBER measurement trigger source is always set to immediate. The FBER measurement does not offer
multi-measurement results. see

FBER measurement results

These the measurement results available from an FBER measurement.
The results of a FBER measurement can be displayed in two ways, (number of errors counted) or (the ratio bad
bits (errors) to total bits counted). For the remote user these results are available by using the FETCh
command, see "FETCh:FBERror:COUNt?" on page 316
manual user will need to select either Count or % from the Measurement Units field.
Manual user results:
• Fast BER Ratio (bad bits to total bits tested)
• Fast BER Count (bad bits found during a measurement)
• TDMA frame Delay (if TDMA Frame Loopback Delay Control = Manual)
• RX Level
• RX Quality
Remote user results:
• Fast BER Ratio (bad bits to total bits tested)
• Fast BER Count (bad bits found during a measurement)
• TDMA Frame Delay (if TDMA Frame Loopback Delay Control = Manual)
• Integrity Indicator
• Intermediate Count
