Step 6. When ready for measurements, cautiously apply DC power to the AUT.

Step 7. Check that the normally factory-installed RF coaxial “jumper”

cable is installed on the rear panel of the Test Set:

￿MS4782X: Between Ext Preamp Input and Output connectors.

￿MS4782D: Between connectors C1 and C2, unless a circulator is installed.

Step 8. If drain current and/or PAE measurements are desired, the optional current probe (ANRITSU part number 2000-1067 or -1085) can be used. Ensure the probe (Figure 3-1)has a fresh battery, and set the zero offset using the MS4623C as follows:

a.Using Domain softkey, set to Transmission & Reflec- tion; using the Display soft key, set for Single Channel; using the Graph Type softkey, set for Real; using the Scale softkey and Data Entry keys, set for 1 mU/Division. Use the Avg key and associated softkeys to set Aver- aging for 10 and IF Bandwidth for 300 Hz. Use the Config key, DATA POINTS and associated softkeys to set for 101 Max Data Points.

b.Use the Measure softkey and select Ext. Analog In.

c.Turn on the current probe and set it for the desired range.

d.Adjust the “Zero Adjustment” thumbwheel until the reading is minimum (typically 0 ￿100￿U).

e.On the current probe:

Orient the probe such that the “Current Direction” arrow points away from the power supply.

Place the jaws only over the DC wire (not both wires)..

Unused Connections The EXT. SOURCE and AUX. OUT connectors must be terminated with 50￿ terminations when not in use.
