After 18 months of development I am offering this amazing Signal Generator, the TPI 1001B. The hardware is amazing and the software is truly awesome.

This document will provide a brief description of the features of the TPI 1001B Synthesizer.


This Signal Generator utilizes the Analog Devices PLL integrated circuit ADF4351.



Output frequency range: 35 MHz to 4400 MHz

Fractional-N synthesizer and integer-N synthesizer

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

Typical rms jitter: <0.4 ps rms


TPI-1001-B Signal Generator FEATURES:


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

External Reference Input is -10dBm to +10dBm 50 ohm. Any standard 10MHz reference will work.

10MHz Reference Output available at back panel. The Reference is accessed via a BNC connector (New Metal Connectors). The output will drive a 50 ohm coaxial cable. DC Coupled 0v to 3.3v

Trigger Output configurable with dozens of trigger events

The unit has been *calibrated and the RF Output Power is accurate within +/-1dBm with 90% of all readings within 0.6dB of reported power 35MHz to 4GHz.


Output Power is available from +10dBm to -70dBm for all frequencies (80dB linear range) See User Manual. Frequencies 35MHz to 2600Mhz -86dBm.

Attenuator Features:

Attenuator section can be automatically stepped at any values between +10 to -80dBm (under the “SCAN” tab)

Attenuator can be manually stepped both up and down.

Step size is adjustable

Attenuator Step speed is adjustable

RF Frequency Step Features:

RF Step function with 1KHz resolution and selectable time per step (under the SCAN tab)

Single Step function Up/Down selectable step size

Single Step Function or Continuous loop

FM / OOK / FSK / Morse Code and Beacon Features :

A rich set of features located under the “Modulation” tab (see photo)

Load Test Scripts, Control Scripts, Modulation Scripts into on-board storage. Set the Control function button to whatever event you are using, release from the laptop, apply 5v battery supply and run your scripts, your beacons or whatever you have configured.

Analyzer Features:

The RF detector circuit is calibrated across the entire 35MHz to 4GHz band. Maximum input is +10dBm and the circuit has greater than 65 dB of dynamic range. Measure amplifier gains, filter responses and even return loss can be measured using an additional external directional coupler. Great for tuning antennas.

Additional features include a “Script” tab that allows you to write your own test sequences and store them in the on board memory.


The System tab monitors all power supplies, sets trigger thresholds, and includes a rich set of features for the Auxiliary input port plus much more. The Aux port can accept data packets to control modulation. It is calibrated and can act as a DVM +5 to -5Vdc.

Battery Power Input to allow the unit to "Stand Alone" and run test sequences stored in memory or Beacons or Morse Code.

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



An Atmel microcontroller (MCU) is used to communicate with the synthesizer, the attenuators, and various other devices within the unit. The MCU also facilitates communication with the host PC via a USB connection. When the unit receives power, the MCU configures the hardware to the state last saved within TPI Link. In this way, the TPI 1001B can operate stand-alone as a fixed frequency signal generator, a scanner, a modulated signal generator, a radio beacon, or can run a stored script. TPI Link is used to control the unit in real-time and to configure the power up state of the unit.


Software is the real prize with this unit. The software is incredible and very powerful.

Future software upgrades for both TPI Link and the MCU’s firmware can be distributed as a single PC application, a new version of TPI Link, which has the MCU’s firmware embedded within it. TPI Link can upload the new firmware directly to the unit without the need for any other programs or hardware.


The Graphical User Interface (GUI), TPI Link, runs on a PC and communicates with the unit via the USB port. TPI Link can completely configure and operate the unit. The unit’s configuration can be saved in nonvolatile (persistent) memory in the unit for use each time the unit is powered. For this reason TPI Link does not necessarily have to be running whenever the unit is in use, but it facilitates many real-time activities and can monitor the various power supplies in the unit.

A very informative “Help” feature is included that describes most of the features found in the TPI 1001B Signal Generator.
