HF Spectrum Analyzer and tracking DDS HF Generator with touch screen (3.2"LCD)

Description

Frequency  range: 100 kHz to 55 MHz*
Floor noise: better  than -100dBm (0.1 pW)
Sensitivity: 2 - 3 uV
Frequency span: variable from 300 Hz to 30 MHz selectable from the touch screen (or rotary encoder).
This multi-function module can also be used as an RF Power Meter (up to 10dBm, maximum frequency 500MHz), X-tal LC Filter Analyzer and VFO HF DDS Generator.
To illustrate, t
he HF DDS Generator can be used as an oscillator for your receiver and the Spectrum Analyzer will locate your frequency when you transmit. It can be easily used as a main or second VFO for vintage transceivers.   More information will be available soon.
This module is similar to the separately listed Antenna Analyzer, only the function for the antenna analyzer was removed, replaced here by the HF Spectrum Analyzer.  The Spectrum Analyzer graph is in real time. The latest version of the software also features a fast real-time waterfall graph across the spectrum.
The package includes the PCB with all required electronics. No other work is required. You only have to connect the power supply (+5 V).  On the board, there are three mini USB connectors - power supply can be connected to any of them.  This is a stand-alone module, with no PC control required.
You are bidding for the complete HF Spectrum Analyzer, as per the pictures. The package includes USB cable and rotary encoder.  The whole module can be controlled by the touch screen. The rotary encoder can be used to set the frequency step and span.
However on the board, there are two switches which have the same function as the rotary encoder. Key A is used to go up, Key B is used to go down.
Feel free to contact me with any questions.

Q.
Can the DDS HF Generator output be used at the same time as the Spectrum Analyser - like a tracking generator? Also what is the output level of the DDS HF Generator and is it constant over the entire operating spectrum?
A.
Yes, Spectrum and DDS Generator can be used at the same time (both in real time )
- DDS is based on IC AD9850
- output level is around 400mVpp.
- output level is a bit lower at the end of spectrum i.e 30 MHz...
Please check the data sheet for more info.
Q.
Can the Tracking Generator be set with an offset, IE 455KHz off the Display frequency.??
A.
On request software can be modify.
