- 100KHz-55MHz use able upto 110MHz(2nd Harmonic)
- Frequency Counter, 55MHz
- TTL Output-Low radiation
S-900 AM/FM signal generator is a low cost equipment ideally suited for education and service applications, it comprises of the following. AM/FM signal generator, which generates frequencies from 100KHz to 55MHz in 6 bands. The second harmonic of the last band generates frequencies upto 110MHz. Frequency counter which measures frequency of the AM/FM and external input. TTL output is available at the frequency readout on the counter. TTL output can be used to drive various circuits during experimentation. AM Oscillator
continuously variable over the whole range with a coarse and fine variable. Modulation frequency 400Hz approx and modulation depth a) Internal Modulation 30% (electronically adjusted b) External Modulation-adjustable. Output amplitude 100mV p-p +2dB into 75 ohms, corresponding to a carrier voltage of 27mV rms approx FM Oscillator
- 80MHz-110MHz (2nd harmonic of band 6)
continuously variable over the whole range with a coarse and fine variable. Modulation Frequency 400 Hz approx Frequency Deviation a) Internal-adjustable 0-22.5KHz from 5MHz to 55MHz b) External-adjustable 0-40KHz from 3MHz to 55MHz for Audio input frequency range 300Hz to 5KHz and a max input of 8V p-p c) Output Amplitude 75mV p-p +2dB into 75 ohms Attenuation - a) step attenuator 5 steps (20dB) each d) Variable attenuator Frequency Counter
