Clock Recovery Commands
CRATe
CRATe
Command
(83496A)
:CRECovery{1 | 3}:CRATe <data_rate>
This 83496A command sets or queries an 83496A module’s data rate setting. Although the
command “RATE” on page 9-7 can be used with 83496A modules, use the preferred CRATe
command in all new programs controlling an 83496A module. The data rate for standard
83496A modules ranges from 50 Mb/s to 7.10 Gb/s. The data rate for Option 200 modules
ranges from 50 Mb/s to 13.50 Gb/s. The data rate can be specified to 6 significant digits. The
default setting is 2.488 Gb/s.
Restrictions
Software revision A.04.20 and above.

INPut
Command
(83495/6A)
:CRECovery{1 | 3}:INPut{ELECtrical | OPTical | DIFFerential | EINVerted}
Selects the clock recovery input on 83495A and 83496A modules. On 83495A modules, OPTical is the default setting. On 83496A modules, ELECtrical is the default setting. The arguments, DIFFerential and EINVerted (electrical inverted), are available on 83496A modules
only.
Restrictions
83495A and 83496A modules. Software revision A.03.10 and above for 83495A module. Software revision A.04.20 and above for support of 83496A modules.

LBANdwidth
Command
(83495/6A)
:CRECovery{1 | 3}:LBANdwidth {BW270KHZ | BW300KHZ | BW1500KHZ | BW4MHZ | CONTinuous}
Sets the loop bandwidth on 83495A and 83496A modules to a value as listed in Table 9-3 on
page 9-6. The default setting is 300 kHz for 83495A modules and 270 kHz for 83496A modules. The CONTinuous argument (83496A Option 300 only) can be returned in queries but
can not be sent in a command string. CONTinuous is returned whenever the loop bandwidth
of an 83496A Option 300 module is set to a value other than the LBANdwidth standard values. When the CONTinuous argument is returned, use the CLBandwidth command to query
the actual value. Refer to “CLBandwidth” on page 9-4.
Do not use this command with 83496A Option 300 modules. Instead, use the command
“CLBandwidth” on page 9-4.
Restrictions
83495A modules , software revision A.03.10 and above. 83496A modules (except Option
300), software revision A.04.20 and above.
