Abstract

In order to sample high-frequency signals, it is necessary to have a needle pulse train and a needle pulse train which is inverted with respect thereto. By means of a switch (T) which is controlled by a clock signal (U), a positive operating voltage (U.sub.B+) is applied for a limited period of time to a first conductor (L.sub.1) and a negative operating voltage (U.sub.B-) is applied for a limited period of time to a second conductor (L.sub.2). The two conductors (L.sub.1, L.sub.2) are connected via a respective diode (D.sub.1, D.sub.2), which are biased differently, to a respective resistor (RV.sub.1, RV.sub.2), which is connected to ground, and to a respective capacitor (C.sub.1, C.sub.2). The respective capacitors connected to a respective further resistors (RL.sub.1, RL.sub.2), which is connected to ground, the needle pulse train being present at one resistor and the needle pulse train which is inverted with respect to the first being present at the other resistor.

Dependent claims

An arrangement for generating a high-frequency needle pulse train and an inverted needle pulse train, comprising:

a switch which is controlled by a clock signal, the switch having a first output connected to a first end of a first conductor having a length L and to a first resistor to which a positive operating voltage is applied, and the switch having a second output connected to a first end of a second conductor, which is identical to the first conductor and which has the length L, and to a second resistor to which a negative operating voltage is applied;
a second end of the first conductor connected to a first terminal of a first diode;
a second end of the second conductor connected to a first terminal of a second diode which is biased oppositely to the first diode;
a second terminal of the first diode connected to a third resistor, which is connected to ground, and to a first terminal of a first capacitor;
a second terminal of the second diode connected to a fourth resistor, which is connected to ground, and to a first terminal of a second capacitor;
a second terminal of the first capacitor connected to a fifth resistor, which is connected to ground and via which the needle pulse train is outputted;
and
a second terminal of the second capacitor connected to a sixth resistor, which is connected to ground and via which the inverted needle pulse train is outputted.
