FM intercom Comprehensive Tester RF Signal Generator 1 MHz–470 MHz Trunking Tester interphone Tester

Note:Only use 12V1A power supply (there is buyer feedback, screen burnout, after our test may be caused by using more than 12V power supply. Please be sure to use the power carefully.
FM walkie talkie integrated tester (radio frequency signal source function, power meter function, frequency meter function, sub tone measurement function)
Emission measurements
1. frequency measurement 10MHz~900MHz resolution 1KHz or 0.1KHz
2.power measurement 0.1W~64W (greater power, please shorten test time and aVoid overheating)
3. sub audio measurement 50Hz~260Hz analog sub tone and standard digital sub sound
Receive measurements
1. RF signal generator 1MHz–470MHz
2. output level:-132dBm to -90dBm
3. single tone modulation:1KHz, 2KHz, 3KHz optional, output modulation system:3K
4. sub tone output:50Hz—260Hz analog sub tone and standard digital sub tone, output range:0.5K
Relay test
Specially designed for debugging and measuring of U/V relay station and FM radio set.The signal generator can operate in duplex mode, i.e.The tested machine is in the firing state and does not affect the generator operation. It can be used in the relay station to transmit measurement.
Working voltage:8-12V DC (DC)
Work current:200mA

F4Key:measurement mode switchingAUTO/ MANUA AUTOWhen the stable frequency is detected, the sub tone is automatically locked and detected, and the results are displayed until the signal disappears, and the signal disappears and continues to be re tested, waiting for the new stable frequency. (you can detect the standard and nonstandard analog tones of your own radio station. If the radio is a digital sub tone, only the standard digital sub tone can be detected, and the nonstandard digit sub tone can not be detected.)

2. vThe intensity of the output signal of the segmentHP8921AQuite
3. USegment output signal strength ratioHP8921A4DBM (when the output of a weak signal is better than this, when the instrument shows -125dbm, the actual value is -121dbm), and the strong signal output is the same as that of HP8921A (for example, about -90dbm)
4. The audio modulation system for the output of the signal is3K
5.The sub tone system in the signal output is0.5K
6.When the frequency meter function, the minimum power input required is 1MW (external antenna, 1W interphone can be measured by close distance launching)
7. power meter in0.2WAbove heelHP8921AYes, less than 0.2At W, the display value is about 20% larger than the actual value (estimated to be 4 to 5).
8. to test the power of more than 5W appropriate to shorten the testing time, avoid testing power for a long time, because the heat inside the board size is limited, to avoid overheating, if you really need to test the power for a long time, please increase the heat sink area and forced cooling fan.
