RD JDS6600 25MHz 2-Channel DDS AW Function Signal Generator

<< < (14/44) > >>

The Feeltech FY6600 has so many differences to the JDS6600:
   "Real" 14 bit DAC vs. discrete resistor driven by FPGA pins
    8192 point arbitrary table at 250 Mhz vs. 2048 points at 200 MHz
    Analog input for modulation source of frequency, amplitude, duty cycle vs. none (unfortunately limited to 1000 Hz)
    Digital modulation mode: ASK, FSK, PSK from external input vs. none

With these differences and more I suggest that the Feeltech FY6600 generator deserves its own thread for discussion.  It would be great to see some pictures of the insides and see some performance testing like I asked Vk2seb to do on the JDS6600.  See https://www.eevblog.com/forum/testgear/anybody-know-anything-about-this-signal-generator/msg1240865/#msg1240865

Hopefully an early FY6600 owner can get this started.

A successful and unsuccessful frequency tuning, the pulses of channels 1 and 2 should not overlap.

Hello,

At the request of @gby

Here is the new Feeltech DDS generator 14 bits-250 msa-8192 points without R2R equipped with an Altera Cyclone IV clocked with SPXO 50mhz .
The model I bought is FY2300H-25 Mhz.

What are the missing ICs for?

Diabolo:
Hello,

For the absent CIs I do not know.
They may be for a more powerful version, or with little interest for this version.
The generator works very well and the signals are good.
Without advertising, I am very satisfied with this device.

Regards,
Diabolo
