Testing P31 on ch.4
Trying to figure out why I cannot record 31P direct detection spectrum.
Connected 1 GHz oscilloscope to output of channel 4 power amplifier through 50 dB attenuated directional coupler. Amplifier was loaded on a 50 Ω coaxial resistor.
Have signal up to 310 MHz, but nothing above.
As a positive control detected 31P frequency at the input of power amplifier. Scope works fine.
Conclusion: AMT3304C-330 could not amplify signal above 310 MHz.
