Fig. 6 Test Circuit
The TEST SET UP shown is for INPUT 0 tests. Similar circuitry is used for each input INPUT in order to test
FREQUENCY RESPONSE and PHASE DELAY. For OFF-ISOLATION, all switches are disabled (CHIP SELECT
= logic 1) and a second enabled GX214A is connected to the output bus. For ALL-HOSTILE CROSSTALK,
three OFF switches are driven from the generator and the fourth is terminated with a 75
resistor. For the
DIFFERENTIAL GAIN and PHASE tests, the output is AC coupled to the output amplifier and the input level
from the generator is modulated with a step signal varying between 0 volts DC and 0.714 volts DC.
