Silly Job Title: Switch Sleuth. I am the Switch Sleuth!

In this video we continue to work through our Maxitronix 30in1, today doing project #6: The Transistor and “Amplification”. In this project we see how an NPN transistor acts as an amplifier.

The HFR trigger coupling I use at the end of the video is called High Frequency Reject, it hides high frequency components from the triggering system and in this case fixed our triggering issue. I haven’t used HFR trigger coupling before. The Rigol user manual for the MSO5000 series doesn’t explain the feature, it just says: “HFR: rejects the high frequency components”.

We use the Rigol MSO5074 Mixed Signal Oscilloscope to examine our input and output voltages, and also to provide a test sine wave for input.

We use the UNI-T UTi260B Thermal Imager to look at the thermals, but there wasn’t anything really to see.

We use the UNI-T UTG962E Signal Generator to provide an input signal, but we couldn’t get it to work properly so we used the signal generate from the scope instead.

We use the Kaisi S-160 45x30cm Repair Mat as our workspace.
