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.

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 ...

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

The low-frequency LCR meter is the instrument of choice for many component measurements. Although manufacturers have developed different measurement techniques, fundamentally the meter compares the ...
