Command Arguments
Parameter (Instruction for Command
Type Code and or Response
Qualifier)
Tx Clock TCK= 1 byte, value 0
Source thru 2
Tx Data Invert TDI= 1 byte, value 0
or 1
Tx Carrier TXO= 1 byte, value 0
State thru 4
Warm-up WUD= 1 byte, value 0
Delay or 1
Countdown CTD= 3 bytes
Description of Arguments
to Query
Command or Query.
Tx Clock Source, where:
0=Internal
1=Tx Terrestrial
2= Loop-Timed
Example: TCK=0 (selects Internal)
Command or Query.
Invert Transmit Data
0=Normal
1=Inverted
Example: TDI=1 (selects Inverted TX Data)
Command or Query.
Tx Carrier State, where:
0=OFF due to front panel or remote control command
1=ON
2=RTI (receive/transmit inhibit)
3=OFF due to ext H/W Tx Carrier Off command (not a valid
argument when used as a command)
4=OFF due to BUC warm up delay (not a valid argument in a
command format.)
Example: TXO=1 (Tx Carrier ON)
Command or Query.
Warm-up Delay for internal frequency reference (OCXO)
0=Disabled (instant on – no delay for OCXO to reach temperature)
1=Enabled (unit waits until OCXO reaches correct temperature)
Example: WUD=1 (selects Warm-up Delay)
Command or Query.
As a query, returns the Warm-up Delay countdown, in seconds
remaining. Range is from 000 to 200 seconds.
As a command, only takes the argument 000. Used to truncate the
Warm-up delay period to zero, forcing the unit into 'instant-on'
mode.
Example: CTD? – responds with CTD=067 – means the unit will
wait another 67 seconds before it will enter an operational state.
CTD=000 terminates the warm-up delay.
