:CRECovery:CLBandwidth

Command Syntax

:CRECovery:CLBandwidth <bandwidth>

<bandwidth> is a double.

Query Syntax

:CRECovery:CLBandwidth?

Description

Sets the loop bandwidth of the JTF Receiver module's clock recovery PLL in Hertz. Because jitter is measured relative to the clock, jitter that is present on both the data and the recovered clock can not be detected by the DCA-X. Jitter that is within the clock recovery module's loop bandwidth appears on the recovered clock. Jitter that is outside of the loop bandwidth does not appear on the recovered clock and can be detected on the data. Selecting the loop bandwidth allows you to eliminate jitter on the recovered clock. The loop bandwidth can be any bandwidth within 30 kHz to 20 MHz specified to 3 significant digits. The default setting is 60 kHz.
