@HopelessDemigod Also function generators, an ultra-low-distortion AF signal generator, a 7 MHz to 4 GHz Agilent Transmitter Tester (basically an FFT specan), oh and a precision buried-zener voltage reference
@HopelessDemigod Oh, and sound pressure level meters, airflow speed measurement (for cooling fans), a set of precision slotted lines for waveguide and coax, sliding shorts, sliding loads and other pre-VNA testgear for measuring impedances and return loss from UHF through to mmWave. I really do have a serious testgear addiction here...
@HopelessDemigod I forgot a really useful tool, a Hall effect AC/DC clamp ammeter. Brilliant for non-intrusive measurement of current from an amp to a few hundred amps, either mains or high-current DC
