The high performance OS2100 and OS2100R series Oscilloscope main frames provide a bandwidth of at least 30MHz with high brilliance and readily ac- cepts all OS2000 series Plug-In modules, The main frame contains the cathode ray tube with the appro- priate brilliance and focus controls, power supplies, main X and Y Amplifier together with a 170nS delay line and 1kHz Calibrator emiconductors are used throughout and all power rails are fully stabilised against power line voltage fluctuations by means of a constant voltage transformer (CVT). Separate Plug-In modules are used for the X and Y deflection thereby ensuring maximum versatility. The cathode ray tube operating at 10kV ensures a clear bright trace at fast writing speeds. The dis- play area is 10 x 6cm and a P31 general purpose phosphor is fitted as standard, with a P7 long per- sistance phosphor being available as an option. Graticule illumination, focus and brilliance are pro- vided as front panel controls with astigmatism and trace rotation, as front panel pre-set controls. A 170nS delay line in the Y deflection system en- ables the leading edge of the triggering waveform to be observed. Dual trace display is achieved by chopped/alternate sweep methods; the beam switch circuit being integral with the dual trace Y Plug-In and the operating mode selected automatically by the position of the time base range switch. The X Amplifier is normally driven from the time-base Plug-In module and is capable of providing sweep speeds of up to 20nS/em. Alternatively, using the Oscilloscope in the XY mode a horizontal bandwidth of at least 200kHz is achievable, Full Z MODULA- TION facilities are provided; via a socket on the rear panel, A noteable feature of the main frame is the use of a constant voltage transformer to stabilize the power rails. Apart from providing adjustment-free operation over the line input range 95 to 130V or 190-260V, its transient suppressing capabilities ensures faultless triggering in the presence of sub- stantial power line noise. It should be noted, how- ever, that the line frequency should be specified when ordering. The construction of the main frame and the availa- bility of blank Plug-In modules makes the OS2100MF ideally suited for special purpose applications. |
