h. Remove the DMM cable from the BNC Tee and from the banana plug

adapter on the DMM.

i. Connect the 50 Ω termination end of the termination/attenuator/ BNC Tee

combination on the sine wave generator cable to the Banana Plug adapter on the
DMM. See Figure 11.

j. Record the DMM reading to 100 μV resolution as ‘Attenuator Output Voltage’ in the

Test Record.

NOTE: This reading should be approximately 200 mV. If it is not, verify that the in-
line attenuator and termination are installed in the correct order. The 50 Ω
termination should be closest to the DMM.
