After 18 months of development I am offering this amazing Signal Generator, the TPI-1001-A. The hardware is amazing and the software is truly awesome.
I have sold over 500 units of my Version 4 and Version 5 Signal Generators without a single return. 100% satisfaction.
This document will provide a brief description of the features of the TPI-1001-A Synthesizer.
This synthesizer 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:
TPI-1001-A Synthesizer FEATURES
Internal Reference is 10MHz Temperature Compensated Clock Oscillator at +/-1.5 ppm over temperature.
External Reference Input is 0 – +10 dBm 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
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 -80dBm for most frequencies (90dB linear range) See User Manual.
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
Modulation Features: FM / OOK / Morse Code and Beacon
A rich set of features located under the “Modulation” tab
The RF detector circuit is calibrated across the entire 35MHz to 4 GHz band. Maximum input is +10 dBm and the circuit has greater than 60 dB of dynamic range. Here is a plot of a 2442 MHz BPF.
This is a plot of a 20 dB gain amplifier followed by a Band Pass Filter (-20dBm RF Input)
Additional features include a “Script” tab that allows you to write your own test sequences and store them in the onboard 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.
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.)
RF Cable included: Quality 8 inch Semi-Rigid with SMA Male connectors
This package includes a CD with drivers and an executable file that will install and run on a PC with Windows 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 1001 A 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.
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 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-1001-A Signal Generator.
