Description

Oszillograph mit mehreren Meßsystemen. Oszillographen mit mehreren Meßsystemen hat man bisher so angeordnet, daß die einzelnen Systeme hintereinander in das Feld eines gemeinsamen Magneten eingebaut wurden.Oscillograph with several measuring systems. Oscilloscope with several Measurement systems have so far been arranged in such a way that the individual systems are one behind the other were built into the field of a common magnet.

Diese Anordnung zeigt sich jedoch insofern nachteilig, als keine Möglichkeit bestand, die einzelnen Systeme voneinander gesondert zu beeinflussen. Eine solche Reguliermöglichkeit war häufig notwendig, um die Empfindlichkeit oder die Dämpfung bei einzelnen Systemen ändern zu können, und zwar insbesondere bei Systemen mit sehr kleinen Maßen.However, this arrangement is disadvantageous in that it is not a possibility existed to influence the individual systems separately from each other. Such Adjustment was often necessary to adjust the sensitivity or the attenuation to be able to change in individual systems, in particular in systems with very small dimensions.

Erfindungsgemäß wird dieser Mangel dadurch behoben, daß für jedes System des Oszillographen ein besonderes magnetisches Feld vorgesehen, wird, indem die einzelnen Systeme innerhalb -der einzelnen Felder eines mehrschenkligen. Elektromagneten angeordnet werden, dessen Schenkel zweckentsprechend mit gesonderten Erregungsspulen versehen sind und dessen Einzelkraftflüsse durch Veränderung der Stromstärke in diesen einzelnen Spulen reguliert werden können.According to the invention this deficiency is remedied in that for each System of the oscilloscope provided a special magnetic field is provided by the individual systems within - the individual fields of a multi-legged. Electromagnets are arranged, the legs of which are appropriately equipped with separate excitation coils are provided and its individual force flows by changing the current strength in these individual coils can be regulated.

In. der Abbildung ist ein Ausführungsbeispiel des Erfindungsgegenstandes schematisch veranschaulicht.In. the figure is an embodiment of the subject matter of the invention illustrated schematically.

s" s., s, s"sin,d die durch das Joch j miteinander verbundenen Schenkel eines vierteiligen Elektromagneten, in deren Feldern a, b, c die drei Meßsystenie in, m" m., eines Oszillographen angeordnet sind. Die Erregung der einzelnen Elektromagnetschenkel erfolgt durch die drei hintereinandergeschalteten Spulenp, p21 p, Die Aufeinanderfolge dieser drei Spulen auf den vier Schenkeln des Elektromagneten sowie der Wicklungssinn der einzelnen Spulen sind so gewählt, daß jedes Meßsystem sich zwischen entgegengesetzten Polen befindet. Die Erregung -der Spulen wird durch die beiden Regulierwiderstände w, w" die den Spulen p. und p" parallel geschaltet sind, geregelt. Durch Einschaltung einer bestimmten Wid-erstandsgröße in die Stromkreise der Spulenp, #undp" kann beispielsweise erreicht werden, daß die Dämpfun#g in allen drei Systemen d.ie gleiche ist.s " s., s, s" sin, d the legs of a four-part electromagnet connected to one another by the yoke j, in whose fields a, b, c the three measuring systems in, m "m., of an oscilloscope are arranged individual electromagnet legs are made by the three serially connected Spulenp, p21 p, The sequence of these three coils on the four legs of the electromagnet as well as the winding direction of the individual coils are chosen so that each measuring system is between opposite poles. The excitation of the coils is through the two regulating resistors w, w "which the coils p. and p "are connected in parallel. By including a certain resistance variable in the circuits of the coils p, # and p", it can be achieved, for example, that the attenuation is the same in all three systems.

Die beschriebene Einrichtung dient vorzugsweise zur Regulierung der Dämpfung und hat hauptsächlich für solche Systeme Bedeutung, die sehr kleine Maße besitzen, beispielsweise für ein System von Elektrokardiographen. Für Systeme mit größeren Maßen kann die Einrichtung zur Einstellung der Empfindlichkeit angewendet werden.The device described is preferably used to regulate the Attenuation is mainly important for systems with very small dimensions have, for example, for a system of electrocardiographs. For systems with The device for adjusting the sensitivity can be used to a greater extent will.

Irn. Ausführungsbeispiel werden zur Regulierung in einfachster Weise Widerstände benutzt, die der Wicklung der hintereinandergeschalteten Spulen pärallel liegen. Die Regulierung kann auch in anderer Weise erfolgen, etwa dadurch, daß für jede Spule ein, besonderer Stromkreis vorgesehen wird.Irn. Embodiment are used to regulate in the simplest possible way Resistors are used that are parallel to the winding of the series-connected coils lie. The regulation can also take place in other ways, for example by the fact that for each coil is provided with a special circuit.
