Instructions for use

1. Ready to operate

1) The power switch is set to "OFF".

2) Connect the power cord and plug it in.

3) Connect the high-frequency signal output line to the "output" terminal.

4) Select the frequency range and adjust the frequency knob to reach the required frequency.

5) The output line should be as short as possible to avoid absorbing unwanted noise. Long shielded lines can reduce the frequency response of high frequency bands, especially when using square waves.

2. connection

When the signal wire is connected to the output, the red wire is high potential (or fire wire), the black wire is the ground wire and is connected to the chassis.

If high-frequency signals are to be connected to the antenna input of the receiver, a 50 to 200 Ω resistor should be connected in series. If receiving with a rod antenna, connect a coil with a few turns of wire on the test line to couple the signal to the antenna.

When detecting a high frequency and an intermediate frequency amplifying circuit, a middle to go through . 1 - 5pF small capacitance, in order to avoid detuning effect.

Note: When directly connecting the test circuit, make sure that there is no high DC voltage in the circuit under test. Otherwise, the frequency may be connected in series a 0.05 [mu] F. - 100pF capacitance.
