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.
Example 10 OUTPUT 707; ":CRECOVERY1:CRATE 4.25E9"
Query :CRECovery{1 | 3}:CRATe?
Returned Format [:CRECovery{1 | 3}:CRATe <data_rate><NL>
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, OPTi-
cal is the default setting. On 83496A modules, ELECtrical is the default setting. The argu-
ments, 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. Soft-
ware revision A.04.20 and above for support of 83496A modules.
Example 10 OUTPUT 707;":CRECOVERY1:INPUT ELECTRICAL"
Query :CRECovery{1 | 3}:INPut?
Returned Format [:CRECovery{1 | 3}:INPut] {ELECtrical | OPTical | DIFFerential | EINVerted}<NL>
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 mod-
ules. 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 val-
ues. 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.
Example 10 OUTPUT 707;":CRECOVERY1:LBANDWIDTH BW4MHZ"
Query :CRECovery{1 | 3}:LBANDWIDTH?
