Eine andere Vorrichtung ist in Fig. 2 wiedergegeben. Hier ist der eigentliche Schwingkreis wiederum durch die Spannungsquelle 1, den Widerstand 2, den Kondensator 3 und die Entladungs-
EMI2.1
der Entladungsstrecke 4 angekoppelt ist, während es mit dem positiven Pol der Spannungsquelle 1 über einen Widerstand 11 verbunden ist. Da das Steuergitter 5 bei dieser Anordnung nicht nur zur lonenabfuhr dient, sondern auch die Synchronisierspannung aufnehmen muss, ist ein Widerstand 9 im Gitterkreis vorgesehen. Dieser Widerstand kann jedoch so klein gewählt werden, dass die Entionisienmgszeit sieh nicht oder nur unwesentlich vergrössert.
Da die vom Messkreis abgegriffene Synchronisierspannung nur dem Gitter 6 der Röhre 10 zugeführt wird, wird auch bei dieser Anordnung dem Messkreis praktisch keine Leistung entzogen und damit eine Rückwirkung des Schwingkreises auf die Messspannung vermieden.
In vielen Fällen kann es zweckmässig sein, ausser der einen Hilfselektrode (6 in den Ausführungsbeispielen) noch weitere Hilfselektroden zur Steuerung der Entladung einzuführen.
PATENT-ANSPRÜCHE :
1. Synchronisiervorrichtung für Elektronenstrahloszillographen, dadurch gekennzeichnet, dass der Gitterkreis der als Kipprohre dienenden dampf-oder gasgefüllten Entladungsstrecke niederohmig ausgebildet und die Kippröhre (4) mit einem Hilfsgitter (6) zur Zuführung der Synchronisierspannung versehen ist.

Another device is shown in FIG. Here the actual resonant circuit is again made up of voltage source 1, resistor 2, capacitor 3 and the discharge
EMI2.1
the discharge path 4 is coupled, while it is connected to the positive pole of the voltage source 1 via a resistor 11. Since the control grid 5 not only serves to remove ions in this arrangement, but also has to absorb the synchronizing voltage, a resistor 9 is provided in the grid circuit. This resistance can, however, be chosen to be so small that the deionization time does not or only slightly increases.
Since the synchronizing voltage picked up by the measuring circuit is only fed to the grid 6 of the tube 10, practically no power is withdrawn from the measuring circuit in this arrangement as well, thus preventing the resonant circuit from affecting the measuring voltage.
In many cases it can be expedient to introduce additional auxiliary electrodes to control the discharge in addition to the one auxiliary electrode (6 in the exemplary embodiments).
PATENT CLAIMS:
1. Synchronizing device for electron beam oscilloscopes, characterized in that the grid circle of the vapor or gas-filled discharge path serving as tilting tubes is designed to be low-resistance and the tilting tube (4) is provided with an auxiliary grid (6) for supplying the synchronization voltage.
