1616 Precision Capacitance Bridge is one of three units (sold separately) required to make up the 1621 Precision Capacitance Measurement System. When used with an oscillator and a detector equivalent to the 1316 and 1238 the 1616 Capacitance Bridge will perform as follows:
▪ Wide range of capacitances can be measured, extending from the resolution limit of 0.1aF to a maximum of 10uF with internal standards, and further with external standards
▪ For 3-terminal unknown capacitors, a pair of coaxial terminals is provided
▪ For 2-terminal coaxial "unknowns", a single precision connector facilitates exacting control of fringing effects

1616 Precision Capacitance Bridge

• 10exp-7 pF to 10 μF - 12 digital readout

• 10exp-10 μS to 1000 μS- 5 digital readout
  10 Hz to 100 kHz

• up to 150-V input from oscillator

• 3-terminal measurements

• coaxial measurements

The 1616 employs a transformer ratio-arm bridge with which unbalances as small as 0.1 aF (10-7pF)
and 100 aS(10-10 μS) can be resolved.
Detection of such small unbalances is aided by ratio-transformer voltage capabilities up to 160 volts
at 1 kHz and by range switching that disconnects the unused internal standards in order to reduce shunt
capacitance across the detector input.
