Abstract :
An electronically tunable admittance bridge is described which is self-calibrating and reproduces DC/LF measurements of resistance/capacitance to better than 2%, with a repeatability of a few microSiemens and a few femtoFarad respectively. It now is used in the 1 MHz to 160 MHz range, primarily as the measuring head in an air chamber for the evaluation of the aging and frequency/temperature characteristics of a multitude of crystal resonators, mounted on a transport rack. The 1 m/sup 3/ temperature chamber has a range of -60/spl deg/C to +125/spl deg/C and a stability of a few milliKelvin at any set-point in that range.
