Query Syntax

:CRECoveryN:LBWTuning:STATus?

Where N identifies slot number {1:8} which is associated with clock recovery module.

Description

Queries the status of the clock recovery Loop Bandwidth Tuning. Loop Bandwidth Tuning is applied when clock recovery is relocked. To enable Loop Bandwidth Tuning, use the :CRECovery:LBWTuning:TORelock command.

Requires FlexDCA revision A.06.40 and above.

Query Response

{TUNed | UNTuned | LTUNed}
TUNed
The loop bandwidth is currently tuned.
UNTuned
The loop bandwidth is not currently tuned.
LTUNed
A "limit tuned" condition exists, and therefore the loop bandwidth may not be the desired value. This condition occurs whenever the loop gain adjustment value has exceeded the allowed internal minimum/maximum limits. This condition may be caused by the following situations:
  • Degraded input signal
  • Low amplitude input signal
