GENERAL DESCRIPTION

The S.43 and D.43 D43R are versatile oscilloscopes offering a wide range of facilities suitable for both general purpose and specialized application. This versatility is achieved by the use of separate plug-in amplifiers for the Vertical Deflection Circuits; a dual-range, general purpose amplifier (type A), a Differential Amplifier (type B) and an Ultra-High Gain Amplifier (type C) are available.

In addition, a special H. F. facility expands the useful triggering range up to 15 Mc/s. The sweep can be triggered from the Line or Frame pulses of a composite television waveform.

Simplicity of circuitry and the “unit” method of construction make an extremely reliable instrument which is easily maintained.

Both the S.43 and D.43 use identical plug-in amplifiers and time-base circuits, the only differences being the CRT circuit and the HT supplies. These are dealt with separately under the appropriate chapter headings.

SPECIFICATION

The Cathode Ray Tube

The 4” flat-faced CRT operates at 4 kV overall, giving an extremely bright, fine trace over the whole of the working area. A P31 phosphor is normally supplied, but longer persistence phosphors are available. A green filter is fitted to improve the contrast under conditions of high ambient light.
