Commands Listed in Alphabetical Order
SFEC12500 sele
cts clock recovery for the 12.5 Gb/s bit rate (potential ITU-T
G.975 related forward error correction rate).
USEr selects c
lock recovery for the user-specified bit rate, when the channel
specified is for an optical sampling module that supports continuous clock
recovery (see the TRIGger:CH<x>:CLKRec:USEr command).
VSR5_3318 selects clock re covery for the 3.31776 Gb/s bit rate, in accordance
with the OIF Implementation Agreement OIF-VSR5-01.0.
XAUI3125 selects c lock recovery for the 3.1250 Gb/s bit rate, in accordance
with the IEEE 802.3ae-2002 standard.
XAUI6250 selects clock recovery for the 6.25 Gb/s bit rate (double the
3.125 Gb/s XAUI rate).
Examples
TRIGGER:CH1:CLKREC:VALUE OC12 sets the clock-recovery value for Channel
1 to the Sonet/SDH OC-12/STM-4 standard.
TRIGGER:CH1:CLKREC:VALUE? might return TRIG GER:CH1:CLKREC:V ALUE
OC48
, indicating that the clock-recovery value selected for Channel 1 is the
Sonet/SDH OC-48/STM-16 standard (data rate of 2488.3 Mb/s).
TRIGger:CLKRec:CRC:AUTOSConfigdev
This command sets or queries the setup auto-save feature of the connected Clock
Recovery instrument. If Auto-save is enabled, the Clock Recovery instrument
saves the current configuration in non-volatile memory. At the next power on, the
Clock Recovery instrument is returned to the saved configuration.
Group
Trigger
Syntax
TRIGger:CLKRec:CRC:AUTOSC onfigdev {ON | OFF | <NR1>}
TRIGger:CLKRec:CRC:AUTOSC onfigdev?
Arguments
ON specifies that Auto-save is enabled.
OFF specifies that Auto-save is disabled.
<NR1>. 1 enables auto-save, 0 disables auto-save.
Examples
TRIGGER:CLKREC:CRC:AUTOSC ONFIGDEV ON enables the auto-save feature on
the Clock Recovery instrument.
