    Excellent signal source for the price! I have include images at 35MHz and 1.9GHz (my spectrum analyzer only goes to 2.0 GHz) Signal level is reasonably accurate (I used a 10 dB pad) and frequency error is small. Very clean signal! Instruction/application manual would be welcome. The Banggood product listing states that a BNC to SMA cable is included - it is not. The ON/OFF switch is always ON (bad switch or solder bridge?)

    Γρήγορη παράδοση. Δεκτή σε καλές συνθήκες. Στον πρώτο (οπτική) έλεγχο φαίνεται ότι έγινε καλά. Θα κάνω τους λειτουργικούς ελέγχους αργότερα.

    Καλή λύση για το ADF4351 σε ένα τμήμα. Μπορεί να τροφοδοτείται από μπαταρία Li-Ion (7,4V). Πολύ χρήσιμο!

    unit looks good, full function, but Output power is only 0 dBm i.e. less than +5 dBm on max Output power setting. Power Settings in 3 dB steps to lower Output power is functioning. Although tehaDF4351 can be set to 1 kHz steps, only 100 kHz steps are possible. Good: full schematic and Firmware is available. unusual: 100 MHz oscillator as a reference source Frequency Offset is within Limits (<+- 1 kHz) in my unit +555 Hz My short tests using a Agilent E5052B Signal Source Analyser and external power supply (ELABO) set to 5 V; max. output power: current draw is 168 mA. Phase noise performance is acceptable. but at all output frequencies strong spurs (168 kHz off carrier) are seen, see the attached phase noise plots:..

    Placed order during Chinese New Year holidays. I thought my order will be delayed because of extension in holidays due coronavirus but to my surprise it took less than two weeks to reach me. Quality, performance and stability is good. The packing is not very good but then you are covered by Banggood warranty and insurance in case of damage. In a way poor packing helps in passing through customs without delay and taxes. Will certainly recommend this product at this price.

    This is a great product! I was in need of an RF signal generator to use with my spectrum analyzer for the intentions of checking resonant frequency and VSWR of FPV antennas. A good quality signal generator typically ranges in price from $500-$5,000 so for $30-$45 depending on the price at the time of purchase, this is a great find! The signal generated is on point and the sweep function works great. The only gripe one could have with it is lack of instruction booklet (although its quite straight forward how to use) and its quite low output power. I use this signal generator in conjunction with a frequency multiplier to generate frequencies all the way up to 8800mhz. For the price, this is a great product!!
