Philips Signal Generator PM5321 PM-5321
The PM 5321 signal generator
was designed for checking and adjusting A.M., F.M. and TV receivers in service workshops.
The frequency range comprises the A.M./F.M. broadcast bands and A.M./F.M./TV intermediate frequency ranges.
The output voltage can be modulated in amplitude over the
entire frequency range in the F.M. band and A.M./F.M.
intermediate frequency ranges, frequency modulation is also possible.
On account of the fact that the apparatus is also suitable for frequency modulation in the I.F. ranges, it lends itself very well for the visualisation of band-pass curves of I.F. amplifiers and I.F. filters on the screen of an oscilloscope.
As a result a receiver can be adjusted much faster than when use is made of the time-consuming system of measuring the
response curve point by point.
