以下図面に従って本考案の一実施例を説明する。In circuit devices and equipment that use two types of circuits to obtain the required characteristics, if it is necessary to adjust or check the input and output characteristics of one of the circuits, the connection points of the circuits are shown in Figure 1. Adjust and check the input-output characteristics of each terminal by disconnecting the output of the front-stage circuit A and the input of the rear-stage circuit B. In actual use, connect the circuits A and B using the relay wire C. This invention provides a circuit device that can be adjusted or checked without interrupting the circuit connection.
An embodiment of the present invention will be described below with reference to the drawings.
第２図において１は所要のインピーダンスを待つ入力端
子で２は出力端子である。In FIG. 2, 1 is an input terminal waiting for a required impedance, and 2 is an output terminal.
３は所要の特性を持つ前段回路で４は３と同一あるいは
異なる特性を持つ後段回路である。3 is a front-stage circuit having the required characteristics, and 4 is a rear-stage circuit having the same or different characteristics as 3.
５は三端子形可変抵抗器５で、この可動端子Ｃに前段回
路３の出力あるいは後段回路４の入力を接続する。Reference numeral 5 designates a three-terminal variable resistor 5, to which the movable terminal C is connected to the output of the front-stage circuit 3 or the input of the rear-stage circuit 4.
図面は前段回路３の出力を可動端子Ｃに接続した場合で
ある。The drawing shows a case where the output of the front stage circuit 3 is connected to the movable terminal C.
可変抵抗器５の一方の固定端子ａに後段４の入力あるい
は前段回路３の出力を接続する。The input of the rear stage 4 or the output of the front stage circuit 3 is connected to one fixed terminal a of the variable resistor 5.
図面は後段回路４の入力を接続した場合である。The figure shows the case where the input of the subsequent circuit 4 is connected.
他方の固定端子ｂ側に１及び２と同一のインピーダンス
特性を持つ端子６を接続する。A terminal 6 having the same impedance characteristics as 1 and 2 is connected to the other fixed terminal b side.
なお回路の特性インピーダンスは高周波回路で用いてい
る５０４７及び７５ｇとして可変抵抗器の抵抗値は特性
インピーダンスに対して充分大きな値とする。Note that the characteristic impedance of the circuit is 5047 and 75g used in the high frequency circuit, and the resistance value of the variable resistor is set to a value sufficiently large with respect to the characteristic impedance.
図で可変抵抗器５をｂ側に設定する事により回路３の出
力に対し可変抵抗器５と回路４が並列に入る事になるが
、この場合特性インピーダンスに対して充分大きな値と
なるので実用上無視できる。By setting variable resistor 5 to the b side in the figure, variable resistor 5 and circuit 4 will be connected in parallel to the output of circuit 3, but in this case, the value will be large enough for the characteristic impedance, so it is not practical. Can be ignored.
よって入力端子１と測定端子ｂを介して前段回路３の入
力一出力特性の調整及び確認ができ得る。Therefore, the input-output characteristics of the front-stage circuit 3 can be adjusted and confirmed via the input terminal 1 and the measurement terminal b.
又後段回路４の調整及び確認を必要とする場合は前述の
手段により前段回路３の所要特性は得られているので、
可変抵抗器５をａ側に設定し入力端子１及び２の出力端
子を介して総合特性として後段回路４の調整及び確認が
できる。In addition, if it is necessary to adjust or check the rear stage circuit 4, since the required characteristics of the front stage circuit 3 have been obtained by the above-mentioned means,
By setting the variable resistor 5 to the a side, the subsequent circuit 4 can be adjusted and checked as a comprehensive characteristic through the output terminals of the input terminals 1 and 2.
この場合３と４の中継点に可変抵抗器が並列に入ること
になるが、特性インピーダンスに対して充分大きな値と
なるので実用上無視することができる。In this case, a variable resistor is connected in parallel to the relay point between 3 and 4, but the value is sufficiently large compared to the characteristic impedance, so it can be ignored in practical terms.
さらに、前段回路３と後段回路４との総合特性は、例え
ばそれぞれの回路が利得を有するものであれば、可変抵
抗器５を調整することによりそのアツテネータ効果によ
って所望の値に設定でき、非常に実用的である。Furthermore, the overall characteristics of the front-stage circuit 3 and the rear-stage circuit 4 can be set to a desired value by adjusting the variable resistor 5 and using the attenuator effect, for example, if each circuit has a gain. It's practical.
