Module output interface |
SMA; 24 hour salt spray anti-oxidation |
Module output signals |
sine wave, square wave; sine wave with 150MHz low-pass filter. Square shaft coupling output. |
Module output channel |
2 channel differential; phase difference is 180 degrees, high frequency output will have phase shift due to filter |
Signal characteristics |
the sine wave has no coupling output; the output has its own DC component. When you are connected to the radio frequency equipment, please add a DC block, or you can directly use an oscilloscope to measure |
Highest main frequency output sine signal range |
1Hz-140MHz |
Max main frequency output square wave signal range |
1Hz-120MHz 10MHz or more requires an oscilloscope input impedance of 50
ohms |
Output amplitude |
sine wave 200mVpp (MAX) square wave 3.3 Vpp; sine wave amplitude decreases with increasing frequency, square wave waveform changes with increasing frequency |
Output impedance |
75 ohms |
