Dpofirs0.5MHZ?470MHZ Generator,RF Generator Audio Modulation Source Conditioning Radio 800Hz,Analog Sub-Tone Digital Sub-Tone,for Aviation/Communication/Manufacturing
Main highlights- Wide Application : Suitable for FM debugging. Generator is widely used in aviation, communication, automotive electronics, manufacturing and other fields. It is absolutely forbidden to press the intercom button to transmit when testing. (self-matching power supply 8V-12V power supply polarity is positive and negative)
- Test methods: During the test, the frequency of the source input transceiver is first set to -100DB or any value. The intercom has audio output and then reduces the output strength of the source. For example, the -120DB just heard the intercom audio but there was noise. The audio just hears that the -120DB value of this output is the receiving sensitivity of the radio.
- Range :Built-in 800Hz audio modulation, with the analog digital CTCSS function. Increase the analog sub-tone digital sub-tone function, strong anti-interference ability, is not interfered. The unit is DBM. General hand sensitivity is -120DBM to -130DBM.
- Range :Built-in 800Hz audio modulation, with the analog digital CTCSS function. Increase the analog sub-tone digital sub-tone function, strong anti-interference ability, is not interfered. The unit is DBM. General hand sensitivity is -120DBM to -130DBM.
- High Quality : Small in size and light in weight, it can be operated with one hand, allowing the operator to reduce wrist fatigue. The audio generator module is integrally formed with a glossy shell without burrs and smoothly installation. The generator shell is made of ABS material, which can resist oxidation and and increase the service life.
- Function : Generator 0.5MHz-470MHz RF Generator Meter Tester for FM Radio Debug Digital CTCSS Singal Output. The accuracy comparison between this source and professional comprehensive measurement is basically the same. The accuracy is very high. Can test the actual receiving sensitivity.
