Instructions for Use
1. Ready to operate
1) The power switch is set to “Off”.
2) Connect the power cord and plug in the plug.
3) Connect the high-frequency signal output line to the “output” terminal.
4) Select the frequency range and adjust the frequency knob to achieve the desired frequency.
5) The output line should be as short as possible to avoid unwanted noise. Long shielded lines reduce the frequency response of high frequency bands, especially when using square waves.
2. connection
When the signal line is connected to the output, the red line is high (or fire line), and the black line is ground and connected to the chassis.
If the high frequency signal is 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 of several turns around the test line to couple the signal to the antenna.
When detecting high frequency and intermediate frequency amplifying circuits, a small capacitance of 1-5pF is passed in the middle to avoid detuning.
Note: When connecting the test circuit directly, make sure that there is no high DC voltage in the circuit under test. Otherwise, a capacitor of 0.05μF-100pF capacitor can be connected in series according to the frequency.
