Information
The JIB and J2B Signal Generators, like their
well-established forerunners
the J1 and J2, are two similar instruments which provide
sinusoidal outputs in the frequency range 15c/s to 5 0 k c
/s. Two
separate output arrangements with continuous level control
are provided
on each instrument. One output is of 600S2 impedance and
isolated from earth, having a maximum output level of 1W; the
alternative output has an impedance of 5fi connected to
earth and with
an output level of at least 500 milliwatts.
The JIB version of the instrument uses a calibrated output
control to
give an indication of output level, while the J2B output
level is indicated
on a front panel meter .
Each instrument contains a resistance-capacitance Wien bridge
oscillator which is connected to the output stage via a
buffer amplifier
. The inherent stability of the oscillator and the use of
feedback
circuits contribute to an output which is substantially
constant over
the whole frequency range. Overall distortion at full output
power
is less than 2% (34dB down on fundamental).
