Product Description

 

 

    The DC1oop-ho1ding circuit has aDC-free output and allows the loop current to be maintained when test instruments are connected to telephone equipment. The connections are balanced and f1oating.

    The high inductance(>1000H) simulated by the GH-1, together with the terminating impe- dance and the existing loop-holding current source, yie1dsa network with avery 1owcut~off frequency(<1Hz) .Consequently, longer settling times occur, particularly in conjunction with switching operations relating to the test point selector MU-30, and these must ba taken into account by means of a delay before the measurement is carried out.
