CAUTION

The AUT RF power output maximum level should be no more than the level shown in the tabulation at right. Otherwise, damage to equipment will occur.

Chapter 3

Operations, General

The basic operation of the Model ME7840A Power Amplifier Test Station (without external preamplifiers) is described in this and the following two chapters: Calibration Operations and Measurement Operations. “Calibra- tion Operations” describes the software measurement calibration func- tion and “Measurement Operations” describes the software measurement function. This chapter describes the setup and general operation of the software. (See Chapter 7 for operation with external preamplifiers.)

Refer to Figure 3-1to identify the equipment named in the recommended power-up sequence for the ME7840A.

Step 1. Connect the output of the AUT to Test Port 2 of the MS4782X. Step 2. Connect the input of the AUT to Test Port 1 of the MS4782X.

Step 3. Ensure that the power rating of the cables is suitable for the test, and that the connections are tightened.

Step 4. Turn on the MS462XC then the MS4782X Test Set.

Step 5. Set the output of the MS462XC so that the AUT output power does not exceed the maximum Test Port 2 input level. See be- low.
