Measure the electrical input to a PR02 resistor and compare the warm-up and cooldown of a heated ceramic coupon against an unheated reference.
Compare two PDB182 wiper ratios at each shaft mark. Swap one load between gangs to see how it changes the readings.
Separate the generator’s displayed load from the physical termination. Measure four 1 kHz cases and estimate source resistance with a Python worksheet.
Measure the voltage across a 74HC4066 analog switch at two loads. Use the readings to estimate its on-resistance.
Try three writes to one FM25V02A scratch byte. Read the write-enable latch and stored value after each attempt to see when the memory accepts data.
Capture a BPW34 light signal near 173 Hz, then see how keeping fewer samples creates a 77 Hz alias without changing the circuit.
Pulse a Coilcraft LPS4018-333MRC through a current limiter and compare its incremental inductance in two measured current bands.
Measure a 1N4148 at 100 µA and 1 mA on two dry temperature plateaus. Use matched currents to separate forward-voltage drift from current error.
Pulse a Panasonic CR2032 with two known loads, measure the voltage droop and recovery, and calculate the effective ratio from paired scope captures.
Measure both windings of a Triad TY-145P at three audio frequencies. Compare a floating meter-only secondary with a 600 Ω load and locate the voltage drop.
