★ Supply voltage: DC 4.5V-5.5V, USB
★ Standby current:
★ Emission current:
★ Output impedance: 50 ohms
★ Output Connector: SMA-K
★ Output frequency range: 35MHz-4400MHz
★ Output stepping: 1KHz-8KHz
★ Output power: -1dBm (W) @ 150MHZ (test power absolute value) about 1 mW
Features:
★ This product operation keyboard has 15 ppt keys, 0~9 number keys, 10, "++" and "--" keys to adjust the frequency to use,
also produces emission output behavior,
short press "++" or "-- ” Key stepping adds one step or minus one step to the original frequency output.
The “ok” button is the output control button. Press it to launch. Press again to stop the transmission.
The emission behavior caused by “++” or “--” needs to press “OK” twice to end the transmission.
This product will display “>>” in the upper right corner of the display when there is output emission behavior
The “C” key will end the transmission and the frequency will be zero.
★ Stepping "" key, cycle selection step "1K", "10K", "100K", "1M"
Take 433Mhz for example, press buttons 4 3 3 0 0 0 by order ,then ok button. That is all.
It is easy to use.

1. Pictured antenna was not included. -1 star2. USB power cord is very short. -1 star3. Overpriced considering it doesn't include everything. -1 starOtherwise Okay. It does output RF signal (if you have your own antenna or cable to verify.)

Does exactly as described! Not fully tested but have had in GHZ range! Might want to buy a wideband amplifier to go with this unless you have a highly sensitive frequency meter! Power output 5 db max from what I’ve seen! But not bad price

Took it out of the box. Plugged in the power source (USB C). The power switch was in the OFF position. Tried to turn the product on. Nothing. DOA! Don't buy, don't believe the reviews. Started a return.

This is an excellent project for kit-building in amateur radio. I built several antenna preamplifiers from kits for the 2m amateur band. This signal source was what I needed to properly tune these preamplifiers. You will also need some type of attenuator to reduce the output of the signal source to prevent overloading. Overall this was an excellent purchase I would recommend to anyone interested in building RF kits.

For the price, this RF generator is hard to beat.pros: easy to use, very good pricing for the features you get. Documentation is reasonably good.in about 10 minutes you will know how to work all the features.cons: just be aware that the harmonic energy levels are quite high. For example, if you output 700 MHz, you will see harmonic energy at 1400 MHz, 2100 MHz, etc. Those levels can be as high as just 10 dB below the fundamental. So of you are looking for a pure, clean RF output, this will not work for you unless you add external filtering.
