Switchable sensitivity

 Higher sensitivity (see pos 1) curve monitoring on ignition modules

 Lower sensitivity (see pos 2) curve monitoring on ignition cables

14.7 SIGNALLING THAT SATURATION AREAS AT THE INPUT HAVE BEEN REACHED

If a smaller than the actual input sensitivity is set (see Fig. 39 or Fig. 50), the so-called “saturation” occurs. The

signal is trimmed and the saturation area is hachured (see the following pictures Fig. 107 to Fig. 110).

saturation area of the channel Ch-A

Fig. 107 – Oscilloscope sensitivity is set correctly to the level of

the driving signal.

Fig. 108 – The driving signal level is higher than the defined

sensitivity of the channel Ch-A (the saturation area is hachured)

saturation area of the channel Ch-A

saturation area of the channels Ch-A & Ch/B

saturation area of the channel Ch-A

Fig. 109 – The driving signal level is higher than the defined

sensitivity of channel Ch-A (the saturation area is hachured). In

channel Ch-B the oscilloscope sensitivity is set in line with the

driving signal level.

Fig. 110 – The driving signals level is higher than the defined

sensitivities of both channels Ch-A and Ch-B (saturation areas

are hachured)

This function reflects in the following areas:

 immediate records, visualization, storage, printing

 long records, visualization, storage, printing

 displaying of the measured values (maximums and minimums)

 displaying of the cursor measurements
