This unit is unbelievable for the price.  Money back guarantee. Don't waste your money on cheap imitations. Look at their feedback and then look at my feedback. They hide their feedback for a reason (just saying).

This unit is completely supported so bid with complete confidence. RF Engineer with over 30 years hardware experience. Made in the great state of Texas!

I have purchased the less expensive models from China and they don't compare both in performance and documentation. And if you need support you are in trouble. My support alone is instantaneous and worth its weight in gold.

Over 1500+ sold and no returns and all positive feedback.

TPI Synthesizer FEATURES

Output frequency range: 35 MHz to 4400 MHz

Low phase noise VCO (1GHz 10Khz offset = -91dBc/Hz)(2.4GHz 10KHz offset = -86dBc/Hz)

Typical rms jitter: <0.4 ps rms

Programmable output power level

Cycle slip reduction

Internal Reference is 10MHz Temperature Compensated Clock Oscillator at +/-1.5 ppm over temperature.

There is a buffered reference output available at front panel. The Reference is accessed via a BNC connector. The output will drive a 50 ohm coaxial cable. DC Coupled 0v to 3.3v

There is an External 10MHz Reference Input on the back panel (BNC). When selected the External input port is active and the on-board reference is powered down. Any standard 10MHz reference will work.

Output Power is available from +10dBm to +16dBm +/- 2dB. I guarantee +15dBm at highest power setting with all frequencies with most frequencies at +16dBm or higher. 4 Power levels

RF Step Features:

RF Step function with 1KHz resolution and selectable time per step

Single Step function Up/Down selectable step size

Single Step Function or Continuous loop

OOK Modulation

OOK modulation. With OOK you can input a pulse train 0v to 3.3V (5V max) using for example an arbitrary function generator. EMC Techs use it for immunity testing by applying a 1KHz 50% Duty Cycle input into the modulation port (see photo of 35MHz RF output with 1KHz On-Off-Keying). FM Modulation ON REQUEST. You Choose OOK or FM

Other Features:

Lock Detect LED front panel. When the LED is on it indicates that the Frequency is locked and stable.

Standard SMA RF output AC Coupled (50 ohm)

Powered by USB 2.0 port (< 250ma)

NOTE: There is no RF filtering of the RF output and you will see the harmonics. If you request 900MHz you will get 1800MHz and 2700MHz and 3600MHz at some lower level. This is not a ten thousand dollar unit and I am designing stand alone Band Pass Filters for the popular frequency bands. Some HAM operators have sent information at 78GHz which requires great phase noise.

Packaged in extruded Aluminum housing with Aluminum End Plates. (I have designed some Band Pass Filters and Low Pass Filters. Let me know if you need something specific.)

This package includes a CD with drivers and an executable file that will install and run on a PC with Win-XP, Vista, Windows 7, Windows 8 and Win 10 (USB cable included ).

SOFTWARE:  Multiple software options give you the full control and access to the TPI hardware features. Android options as well.

LabView : The LabView module is on the CD and was my original software platform. You do not need to own LabView to use it. I am no longer upgrading this platform and I keep it only because some of you will want to integrate this into other Virtual Systems. It works great. Ask me if you are interested in the Native software .

SynthMachine: available for all versions of Windows from XP to 8, provides a versatile control panel enabling you to set the frequency and power for a constant output, and setup for frequency or power scanning using either a preset delay between steps or manual stepping.  SynthMachine also enables you to select an external reference source, gives you control of most of the PLL parameters, and even lets you edit the calibration parameters.  If you find a configuration you like, the parameters can be set as the default for the next time SynthMachine is launched.

I have included a simple scripting feature in the latest software release. This allows you to write and save different "Test Sequences" or a series of events. (See photo)

If you are interested in embedding the TPI board into your system, RFControl is available for an additional $100 and it will save you days of programming. Contact me for more information about RFControl.

RFControl is an enhanced version of SynthMachine that includes a TCP/IP server interface.  All of the control buttons and settings that are available from the front panel are available to your application through this interface. 

RFControl comes with RFShell, a small scripting client that can read commands from a file and send them to the TPI board.   A complete Python class source code is available. Perl, c# and Tcl programming examples are provided to help you quickly integrate the TPI board into your system.  You can also use the built-in VISA TCP/IP mode built into many products to send commands to RFControl.   Some real time software support is included.

SOFTWARE fun: A very slick Morse Code Module is also included.  With the Morse Code module, whatever you type into the window is sent in Morse code using OOK modulation. I have used it at 40 wpm. There is an additional "Beacon" mode that continuously sends a fixed message until you stop it.  A third mode lets you use your mouse or any other key on the keyboard to send your own Morse Code. This software module is completely appropriate for the coming apocalyptic events about to unfold.

This is a wide band synthesizer. This is a very inexpensive solution for a stable frequency source for a number of applications to include production test set ups, antenna testing, Range tests, bench testing. It is a lot easier to lug around than an old HP unit at less than 12 ounces.

International buyers: USPS Rates have increased and the cost for Express shipping is greater than $60 but for now I will honor the $45 International shipping

This product is Made in USA by an RF Engineer with 30 years of experience in product design. It is a superior product versus similar eBay offerings and it is at a less expensive cost.
