This command sets/queries loopback delay control mode. If loopback control mode is automatic (auto on), the test set will determine the frame delay value that will allow correlation between uplink information bits with downlink information bits. . If loopback delay control mode is manual (auto off) , the test set will use the frame delay value entered in the TDMA Frames Delay field. Refer to SETup:FBERror:MANual:DELay . Refer also to the Fast Bit Error Measurement Description for a description of frame delay and its use in the fast bit error rate measurement. |

This command sets/queries the number of frames the test set will use to correlate uplink information bits with downlink information bits when loopback delay control mode is manual (auto off). To set the loopback delay mode to manual, refer to SETup:FBERror:LDControl:AUTO . This value is displayed in the TDMA Frames Delay field when Auto is not displayed. (If you want to display this value and Auto is currently displayed, press the front panel key labeled MANUAL). Refer to Fast Bit Error Measurement Description for a description of frame delay and how it is used in this measurement. |

This command selects/queries the Signalling loopback control state for an FBER measurement. When the state is set to on, the test set will automatically send the command for Type C (burst-by-burst) loopback to the MS when a FBER measurement is activated, and then set loopback to off when the measurement is complete. The loopback type is controlled manually from the Mobile Loopback F12 key, see CALL:TCHannel:LOOPback for a program example and details about the command. |
