or apply a DC voltage corresponding to the minimum negative peak value to the signal end of R1, and adjust R8 for zero indication on the meter. Now apply the maximum level—I chose +10 dBu—and set R11 ...

A Daven resistor network reduced the output from +11 dBm to telco-required +8 for 3 dB line isolation, sent the proper voltage to the meter ... the scale is far right of center, permitting maximum ...

There’s hardly any piece of test equipment more fundamental than a volt ... of the meter is interesting. There were several unique features. For example, if the meter goes full scale a little ...
