  • Notes

  • The Model TVR-C3 is a small, truly portable oscilloscope. A new type of cathode ray tube, type DG7-32 together with miniature components have enabled a reduction in the weight and size of the instrument, whilst still offering the quality and features available in larger models.

    This oscilloscope will be found quite suitable for TV servicing and general servicing in repair shops, laboratories and workshops. The selectivity curve of TV, RF, and IF circuits can be displayed on the cathode ray tube screen in conjunction with a "Sweep Oscillator" and all adjustments and aligning can be done while actually observing their effect on the curve shape.

    Vertical amplifier response to 1 Mc/s enables examination of synchronising and deflection waveforms. Other applications include checking audio amplifiers, broadcast receivers, tape recorder servicing, distortion measurements etc. A tape playback head can be directly attached to the vertical amplifier of the CRC and output checked, including supersonic bias.

    SPECIFICATIONS:

    • Cathode ray tube DG7-32, diameter 2¾". Green trace
    • Sensitivity: 22V R.M.S. or 62V peak-to-peak/inch direct to plates.
    • Horizontal sensitivity: 20V R.M.S, or 56V peak-to-peak/inch direct to plates.
    • Input impedance directly to plates from front panel 3 megohms, 7 pf.
    • Time Base:   Miller - phantastron time base with paraphase amplifier - push-pull deflection of trace when horizontal amplifier is used to extend the trace.
    • Power consumption: 33W.
