Category: Measurement instruments
Group: Other
Description: Universal Bridge
                                    Universal Bridge B221 operates at audio frequencies
and provides accurate values for all types of electrical
components over an extremely wide measurement range.
The internal Standards are of conductance and capacitance,
but the Bridge measures positive or negative conductance
or resistance, together with capacitance or inductance.
Two displays provide, simultaneously but without any
interaction, values for the resistive and reactive terms
of any Unknown, including all cyphers, the decimal point
and the units of measurement.
The Bridge has an internal source and detector operating
at a fixed frequency (normally 1592 c/s to simplify calculations
involving 2nf) but can be operated with an external
source and detector at any audio frequency. Suitable
instruments for this purpose include the Wayne Kerr
Audio Signal Generator SI21 and (above 100 c/s) Waveform
Analyser A32I. Full details of these instruments are
available separately: their use with the B22I Bridge
is described in this Manual.
