Setting Measurement Conditions

This section explains how to set the measuring conditions.

• The following explanation of how to set measuring conditions assumes that you are using the keys on the front panel of the E4982A. To understand the setting procedure when using a keyboard or mouse, see Key Operation Overview

• Presetting the E4982A

• How to set the measurement point (frequency/averaging factor level/oscillator level)

Presetting the E4982A

1. Press the Preset key on the right corner of the front panel.

2. Click the Preset softkey to preset the E4982A to its initial set state, which is also known as Preset state.

How to set the measurement point (frequency/averaging factor level/oscillator level)

With the E4982A, you must enter the desired measurement point along with its conditions in the measurement point setup display before starting measurement. The following procedure shows a case when four measurement points with different frequencies (i.e., 1 MHz, 10 MHz, 100 MHz, and 1 GHz) are set up.

For all four points, the averaging factor is assumed as 1 and the oscillator level as -13 dBm.

1. Press the Stim Table key and the measurement point setup display appears.

2. Press the key once to move the cursor to the Frequency cell of measurement point 2.

3. Press 1 > 0 > M/μ consecutively and set the frequency of measurement point number 2 to 10 MHz.

4. Press the 1 > 0 > 0 > M/μ consecutively and set the frequency of measurement point number 3 to 100 MHz.

5. Press the 1 > G/n consecutively and set the frequency of measurement point number 4 to 1 GHz.

6. Press the Point Meas key to go back to the first single point measurement display.

7. Refer to How to Change Oscillator Level to learn how to change the oscillator level and its unit.

8. Refer to How to Change Averaging Factor to learn how to set the averaging factor.
