Most radio engineers today will recall uncomfortable evenings and cold nights spent in dog houses making antenna impedance measurements, or worse, still trying to balance a laboratory model GR bridge ...

Some 30 years ago, my complement of RF test equipment consisted of a General Radio 1606B impedance bridge (GR bridge), a Potomac SD31 synthesizer-detector and a Delta OIB-1 operating impedance bridge.

Impedance metrology underpins the precise characterisation of electrical components and materials by quantifying their complex resistance and reactance across a broad frequency spectrum. Contemporary ...

My wish list for highly-integrated measurement instruments includes impedance or RLC meters. These instruments are especially interesting because they allow for so many different design alternatives ...
