Units: When entering frequency numbers the units <U> entry is optional. You can specify M for
MHz, G for Gigahertz, or K for kilohertz. You can also specify H for Hertz. If you do not specify
the units, the synthesizer will make logical assumptions. For example, if you entered 2450 with
no units, the synthesizer would know you meant MHz since it can't produce 2450Hz, or
2450kHz, or 2450GHz.
Parameters: Certain command inputs are binary in nature. In most cases a binary input
parameter such as Enable can also be a "1" and Disable a "0". Also references to External can be
a "1" while internal is a "0".

Query syntax
Query syntax is used to check the state or parameter of a command function. If a command
has a query mode, and most do, then enter the command with a "?" or enter the command with
no parameters.
4.4 General Commands
Baud
4.4.1
Note: Baud has a query, the command "baud or baud?" followed by a RETURN will display
//Available rates = 9600, 19200, 38400, 57600, 115200, 230400, 460800, 921600.
You may send the command "baud" followed by any of the allowable baud rates, 9600, 19200,
38400, 57600, 115200, 230400, 460800, and 921600. Once the baud rate has been changed the
terminal program will no longer be able to communicate. Close the terminal program, change
the terminal program baud rate to match the synthesizer's baud rate previously changed, and
then reconnect at the new baud rate.
Source <1|2>
4.4.2
The 5009 contains two independent and identical signal sources. Commands are directed to a
particular source by sending the s (select source) command. The select Source command is
takes effect for all following commands and it is not necessary to precede any subsequent
command or commands with the select source command.
STATus
4.4.3
Returns the Manufacturer's name, model, serial number, firmware version, firmware build date
and time, uP clock rate, power supply voltage (VBAT), internal temperature, LM, and UID.
LocK?
4.4.4
Returns the status of the PLL lock condition from both sources. LocK1? And Lock2? Returns he
status of each source separately.
ID
4.4.5
This query outputs an identifying string. The response will show the following information:
Valon Technology, 5009, serial number, firmware revision. The firmware version can also
inform the UI what attributes are available such as number of sources, attenuators, modulation,
etc.
