Operating Features and Specifications
Error Location (Agilent 71612 or Agilent 70843 Option UHJ)
Sync-loss Seconds
Displays the number of seconds the error detector lost pattern synchronization during a
gating period.
Frequency Measurement
The incoming clock frequency is measured and displayed to five significant digits.
Result Logging
Refer to Chapter 10 Data Logging for information on logging results.
Error Location (Agilent 71612 or Agilent 70843 Option UHJ)
Error location is available only for RAM-based patterns. It has three forms:
•BitBER
• Error location capture
•BlockBER
Bit BER
Bit BER measurements are measurements made on a specific bit in a RAM-based user
defined pattern. The specific bit is the “BER location” and is specified by an address. This
measurement aids in identifying systematic errors causing a specific bit to change value.
Measurements
• Bit BER - BER of the BER location
• Bit error count - error count of the BER location
• Delta bit BER
• Delta bit error count
Bit BER and Bit error count are affected by gating like normal BER. Delta bit BER and
delta bit error count run continuously like normal delta BER.
The BER location may be specified by the customer as an address. After the location is
specified gating is restarted if the instrument was gating before the location was specified.
Error location capture
Error location capture allows you to capture the actual position of errored bits in a user
defined pattern.
