:CHANnel:SCRecovery:PLLoop:FZERo
Command Syntax
:CHANnel{1:8}{A|B|C|D}:SCRecovery:PLLoop:FZERo <frequency>
<frequency> is a double.
Where the required specifier {1:8}{A|B|C|D} identifies a channel by its module slot number and channel letter. For example, channel 3C (CHANnel3C).
The channel specifier will fail if it does not include a slot number. If instead the suffix's channel letter is missing, the command defaults to letter A. As a result, the best practice is to always explicitly specify the channel by including both the module slot number and channel letter.

Description
For the selected channel's software clock recovery, sets the frequency at which the OJTF starts to roll-off at 40 dB/decade for a third-order PLL loop. To set the frequency at which the JTF starts to roll-off at 40 dB/decade, use the :CHANnel:SCRecovery:PLLoop:FPOLe command. To enter the frequency that sets the approximate loop bandwidth of the PLL, use the :CHANnel:SCRecovery:PLLoop:FGAIn command. To select a third-order PLL loop, use the :CHANnel:SCRecovery:PLLoop:ORDer command.
with Zero, Pole, and Gain Frequencies
Before this command can take effect, you must disable shared acquisition parameters with the :CHANnel:RTSCope:TRACkcommand.
Requires FlexDCA revision A.06.70 and above.
