Leveling with Power

Leveling with a power meter is similar to leveling with a diode

Meters

detector. Figure 1-13 shows the setup for power meter leveling.

Figure 1-13. Leveling with a Power Meter

1. Set up the equipment as shown. Be sure to set the power meter to

manual range mode and note the range.

2. Refer to menu map 1.
3. Press

Select

Point

.

Select

Range. Enter the range value set for the power

meter as noted in step 1.

6. Select Coupling Factor , press

Unlike detector leveling, power meter leveling provides calibrated

power out of the leveled RF port.

Hint

To obtain flatness corrected power refer to “Optimizing Synthesizer
Performance, Creating and Applying the User Flatness Correction
Array,” later in this section.
