Step 2. Set DC power supply output voltage +5 V. Connect TP2 (GND) on the bias
interface simulator to ‘-’ terminal of the power supply. Then connect TP1
(Vcc) on the simulator to ‘+’ terminal of the power supply. (refer to Figure
Figure 4-15 and Figure 4-16.)
Step 3. Interconnect the bias interface simulator and bias interface connector on the
rear panel of the E4980A/ E4980AL with the bias interface cable as shown in
Figure 4-16.

Step 4. Turn the E4980A/ E4980AL ON.
Step 5. Press [System].
Step 6. Press the SELF TEST softkey to display the SELF TEST page.
Step 7. Use the CURSOR arrow keys to move the cursor to the TEST MENU field.
DC power for the bias interface simulator can be supplied from the
E4980A/ E4980AL instead of from an external DC power supply.
Connect using the adapter between the bias interface connector on the
rear panel of the E4980A/ E4980AL and the bias interface cable, when you
execute this step.
