Programming With a Terminal Program
In some instances the user will not want to use the MS-Windows based V5009CM GUI and will
want to communicate directly with the synthesizer using simple commands. The following
section describes the available commands.
4.1
Introduction to Commands
The synthesizer can be programmed using a set of simple commands accessed by the micro-USB
serial interface or TTL USER Port and either a terminal emulator program such as Putty,
TeraTerm or the recommended 5000term.exe. The 5000term.exe is a download available on
the valontechnology.com website. A direct digital TTL interface is also available at the 8-pin
User Port.
Once connection to the serial port has been established, type "help" in the teminal program for
a list of the latest vailable commands.
By convention, the 5009 module is refered to as a dual frequency synthesizer. However in this
context, each of the two internal synthsizers will be refered to as a source.
4.2
Syntax notes:
[ ] means optional entry may be used. SS1; f ;[CW];2550 MHz.
< > String value to be entered: SOURce; Frequency 1 ;CW <2550> <MHz>.
| Indicates one of two choices are available. SOURce<1|2>;Frequency 2550 MHz.
Upper-case lettering indicates that the upper-case portion of the command is the
minimum required for the command. For example, F is the minimum required for
the Frequency command. Note: The minimum required character does not have to be
sent as upper case.
Lower-case lettering indicates that the lower-case portion of the command is optional; it
can either be included with the minimum required upper-case portion of the command
or omitted.
Commands must be separated by a semi-colon (;) and no action is taken until a carriage
return is sent. If only a single command is being sent then the semicolon is not
required.
Spaces between command entries are not required and are ignored.
The 5009 contains two RF synthesizers and in this document are referred to as sources. Source
and synthesizer are used interchangeably throughout.
