6 1 9 . Output Path to 3582/3585
This test checks the circuits in the signal path shown in Figure 6-11. If the previous tests have
been performed, the only circuit being checked that hasn't been tested, is switch S5 A
voltage is generated by the Digital to Analog Converter. The voltage is then measured by an
-hp- 3455A Voltmeter at the IMO OUTPUT to 3585A and at the Channel B Output In this
test, the Adaptive Coupler is in the DC mode (L2=0). At one point in the program, the user
is given the option of discontinuing the test if it appears to be failing. If he chooses to con
tinue the program, the test is completed and the results are printed.
Initializing the Test
With the High Frequency Menu displayed, press shift SFK Kl (-hp-9836) or SFK Kl 1 (-hn-
9845B) to initialize the test. After initialization, follow the instructions displayed on the
computer,
