Measurement Results
• Recv Level - The voltage level of the signal measured at the Rx jack.
• Frequency - The frequency of the signal measured at the Rx jack. The E1 Pulses
indicator must be active for this measurement to be displayed.
• Elapsed Time - Indicates the amount of elapsed time since the last measurement
reset.
• BPV Errors - A tally of the number of BPV errors since the last measurement
reset.
• BPV Error Rate - The percent ratio of BPV errors to total bits transmitted since
the last measurement reset.
• BPV Errd Secs - The number of one second intervals since the last
measurement reset that contained BPV errors.
• Frame Errors - A tally of the number of Frame errors since the last
measurement reset.
• Frame Error Rate - The percent ratio of frame errors to total bits transmitted
since the last measurement reset.
• Frame Errd Secs - A tally of the number of one-second intervals since the last
measurement reset that contained frame errors.
• Signal Loss - A tally of the number of one-second intervals since the last
measurement reset that contained signal errors.
• Frame Sync Loss - A tally of the number of one-second intervals since the last
measurement reset that contained frame sync loss.
• Excess Zeros - A tally of the number of one-second intervals since the last
measurement reset that contained excess zeros.
• All 1's - A tally of the number of one-second intervals since the last
measurement reset that contained the AIS pattern.
• Error Free Seconds - A tally of the number of one-second intervals that were
error free since the last measurement reset.
• Errored Seconds - A tally of the number of one-second intervals since the last
measurement reset that contained errors such as BPVs and frame errors.
• Severe Errored Seconds - A tally of the number of one-second intervals since
the last measurement reset that were severely errored.
• Available Seconds - A tally of the number of one-second intervals since the last
measurement reset that were available for service.
• Unavailable Seconds - A tally of the number of one-second intervals since the
