Response to Query
CnC
Frequency
Range/offset CCF= 3 bytes Command or Query. (CnC parameter)
The maximum value that may be entered as the CnC Sweep
frequency range depends on the Rx symbol rate as follows:
18ksps to 32ksps:
±
1 to the symbol rate (ksps)
32ksps to 389ksps:
±
1 to 32 kHz
389ksps to 2000ksps:
±
1 to 10% of sym rate
>2000ksps:
±
1 to 200 kHz
Example: CCF=030
CCF=
CCF?
CCF*
CCF# CCF? CCF=xxx
(see description of
arguments)
CnC
Min/Max
Search Delay CSD= 6 bytes Command or Query. (CnC parameter)
CnC min/max delay value in milliseconds. Maximum allowable value
is 330ms.
Format: CSD=xxxyyy where
xxx=minimum delay
yyy=maximum delay
Example:
CSD=010325
CSD=
CSD?
CSD*
CSD# CSD? CSD=xxxyyy
(see description of
arguments)
G.703 Clock
Extension CEX= 2 bytes Command or Query. ( FAST option)
G.703 Clock Extension, where:
a=G.703 Clock Extension Mode
0=None
1=TxLock
2=RxEnable
b=G.703 Clock Extension Interface
0=T1
1=E1Bal
2=E1Unbal
Example: CEX=12 (Sets Tx Lock to E1 Unbalanced)
Note: Not all CEX modes are valid all the time.
For argument a:
If Data Interface (ITF) is G.703, only 0=None is allowed.
If Tx clock (TCK) is not Internal, 1=TxLock is not allowed.
