Connect the test equipment as shown in Figure 7.2.
Plug the ASP card into the T1560-05 rack extension card and insert it into the
appropriate position in the rack.
Inject a balanced (earth isolated) 1kHz signal at a level of -10dBm (600
Ω
) into
"I/P-1" of the appropriate port on the T805-04 backplane.
Monitor pin 24 of IC210 and adjust RV201 to obtain a level of 0dBm. This sets the
maximum input level into the A/D converter.
Monitor the balanced signal at "O/P-1" (on the backplane) with an earth isolated
audio voltmeter and adjust RV202 for an output level of -10dBm into 600
Ω
