0.5MHz470MHz RF Signal Generator Meter Tester For FM Radio

The accuracy comparison between this signal source and professional comprehensive measurement is basically the same. The accuracy is very high. Can test the actual receiving sensitivity of the .

Features:

Suitable for FM

debugging.

Built-in 800Hz audio modulation, with the analog digital CTCSS function.

The unit is DBM. General hand sensitivity is -120DBM to -130DBM.

The greater the sensitivity to a negative number, the higher the sensitivity.

The signal source cannot input .

It is absolutely forbidden to press the intercom button to transmit when testing. (self-matching

supply 8V-12V

supply polarity is positive and negative)

Specifications:

Material: ABS

Color: blue

Frequency: 0.5MHz-470MHz

Signal strength: -70-132dBm

Built-in 800Hz audio modulation

Add the analog digital CTCSS function

Use 8-12V

supply, frequency 7 digits

For example: 439.6000MHz shows 4396000KHz

Signal strength -70-132dBm valid, other values are invalid.

Audio modulation is only about 800Hz, other values are invalid.

Item size: 155 * 120 * 63mm / 6.1 * 4.7 * 2.5in

Item weight: 271g / 9.6ounce

Package size: 210 * 160 * 70mm / 8.3 * 6.3 * 2.8in

Package weight: 303g / 10.7ounce

Test methods:

During the test, the frequency of the signal source input transc eiver 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 signal but there was noise. The audio signal just hears that the -120DB value of this output is the receiving sensitivity of the radio.
