you are a new purchaser of our 5007 or 5008 Dual Synthesizer Module, you will want
to download the Configuration Manager software so that you can program your
you are already using the 5007 or 5008 you will want to check here for updates
and download the latest version.† We
also list any bugs we know about and invite your feedback. And if you donít
already have one hereís where you can get the latest data sheet.†
The 5007 and 5008 use the same, 5007 Configuration Manager.
Config Mgr Admin Version Admin Version 1.5.4 setup.exe Executable program
will self-install the 5007/5008 dual synthesizer Configuration Manager.† This GUI will let you setup the synthesizer
frequencies and save settings.† This
version will also allow you to see all the register settings, which can be
handy if you are developing your own drivers and control software.
Guide for Admin Version †The Userís
guide is a document that describes the installation and use of the
Configuration Manager.† Use this guide

trouble with your USB adapter.† Read this.
Phase noise and Jitter
makes a mistake sometime. Right?)†
Hereís the ones we know about.†
- Not locking on
power-up.† Some lab power supplies together with
long test leads can cause the 5007 low drop-out voltage regulators to
become unstable.† We recommend
connecting to the power supply with the 12Ē cable supplied.† If this is not practical, then adding a
100uf/10V capacitor at the end of the 12Ē cable should cure this
- Not locking at certain
frequencies.† If you find that the 5007
becomes unlocked at specific frequencies when the VCO is in the
3800-4100MHz range then check to see that the Reference Frequency Doubler
mode is enabled.† This is in the
Set Frequencies menu. The 5007 loop filter is designed for a PFD frequency
of 20MHz so when using a 10MHz reference frequency you should enable the
reference doubler.† This will
ensure the lowest, close-in, phase noise and stability.
- User version 1.2.0 and Admin version
1.5.0 fixes previous version bug in Read Registers not responding with
correct value for frequency settings higher than 4294MHz.
- Trouble locking above
4000MHz.† If you experience
trouble with the 5007 locking correctly above 4000MHz, download the
current version of the Configuration Manager Admin Version.† Set the RF Prescaler to 8/9 (probably
was set to 4/5). †
- Admin version 1.5.1 fixes previous bug in
all version.† The Admin version
lets the user set the prescaler to either 4/5 or 8/9.† The prescaler should be set to 8/9
generally and in the case of the 5007 there is no advantage to setting
4/5.† Previous versions would set
the prescaler to 4/5 regardless of what the configuration manager
- Configuration Manager
(User 1.2.0 and Admin 1.5.1) Bug in the FILE/GET CONFIGURATION command.† This bug would cause the Synthesizer-2
(not Synthesizer 1) frequency to display incorrectly.† This bug was fixed with the release of
Admin Version 1.5.3 and the User version is discontinued.
