Description

Verfahren zur Bestimmung der Frequenz, insbesondere bei Impulssendern Es ist üblich, zur Frequenzbestimmung bei Kurzwellensendern sogenannte Wellenmesser zu benutzen. Bei der Frequenzbestimmung pflegt man in der Weise vorzugehen, daß man an den Sender, dessen Frequenz bestimmt werden soll, einen Schwingkreis mit veränderbarer Kapazität oder Induktivität ankoppelt. Die in diesem angekoppelten Kreise induzierten Spannungen werden etwa über eine Diode dem Anzeigegerät zugeführt. Bei Sendern mit Impulsbetrieb ergeben sich insofern Schwierigkeiten, als die für die Anzeige zur Verfügung stehende mittlere Energie verhältnismäßig gering ist. Man kann nun zwar mit einer Verstärkung der Impulsfrequenz arbeiten, jedoch bedeutet dies in den meisten Fällen einen unzulässig hohen Aufwand.Method for determining the frequency, especially in the case of pulse transmitters It It is common to use so-called wave meters to determine the frequency of short-wave transmitters to use. When determining the frequency, one usually proceeds in such a way that one to the transmitter, whose frequency is to be determined, with an oscillating circuit variable capacitance or inductance coupled. The ones linked in this one Circuits induced voltages are fed to the display device via a diode, for example. In the case of transmitters with pulse operation, difficulties arise as the for the average energy available is relatively low. You can now work with an amplification of the pulse frequency, but means in most cases this is an unacceptably high effort.

Die Erfindung gestattet es, den geschilderten Nachteil zu vermeiden, und zwar dadurch, daß bei einem Verfahren zur Bestimmung der Frequenz, insbesondere bei Impulssendern, als Indikator eine Funkenstrecke verwendet wird, die während des Meßvorganges vorzugsweise mittels einer Lupe beobachtet wird und deren Elektroden beispielsweise aus zwei in gegenseitigem Abstand von einigen zehntel Millimetern angeordneten elektrischen Leitern bestehen. The invention makes it possible to avoid the disadvantage described, namely that in a method for determining the frequency, in particular In the case of pulse transmitters, a spark gap is used as an indicator, which during the measuring process is preferably observed by means of a magnifying glass and its electrodes for example from two at a mutual distance of a few tenths of a millimeter arranged electrical conductors exist.

Die Elektroden bei der Funkenstrecke zur Durchführung des Verfahrens nach der Erfindung können in bekannter Weise innerhalb eines Vakuumraumes angeordnet sein. Zweckmäßig wird die Funkenstrecke mit der zur Beobachtung dienenden Lupe baulich vereinigt, etwa dadurch, daß die Lupe in die Wandung des Vakuumraumes eingesetzt wird, der die Elektroden der Funkenstrecke auf nimmt Die Erfindung weist besondere Vorteile bei der Bestimmung der Frequenz von Impulssendern auf, weil beim Impulsbetrieb trotz kleiner mittlerer Energie die induzierten Spannungen sehr groß sind. The electrodes at the spark gap to carry out the procedure according to the invention can be arranged in a known manner within a vacuum space be. The spark gap is expediently structured with the magnifying glass used for observation united, for example in that the magnifying glass is inserted into the wall of the vacuum space who takes the electrodes of the spark gap on The invention has special Advantages in determining the frequency of pulse transmitters because of pulse operation despite the small average energy, the induced voltages are very high.
