POWER SWEEP, ONE TONE

OPERATIONS, MEASUREMENT

5-8POWER SWEEP, ONE

This measurement module has three variations of possible Measurement

TONE

Types: Power Sweep (single frequency), Multi Frequency Power Sweep,

 

Gain and IMD.

Single Frequency

Procedure.

Power Sweep

 

 

 

 

Prepare the ME7840A as shown in Chapter 3.

 

 

Enter the appropriate test values in the displayed

 

 

User Input screen. The input fields are described

 

 

below:

 

 

￿ Measurement Type: Drop down options set to

 

 

 

 

“Gain and Phase ” for this test.

 

 

￿ Main Tone (MHz): CW Frequency setting for

 

 

source 1.

 

 

￿ Start Power (dBm): Power will be swept starting

 

 

at the start power (input RF power to AUT). Both

 

 

sources are simultaneously set to each power set-

 

 

ting. The stop power is also entered in the “to” win-

 

 

dow.

 

 

￿ Data Points: Number of data points in power

 

 

sweep.

 

 

￿ Increment Power (dBm): Value to increment

 

 

power for each data point (calculated and dis-

 

 

played only).

 

 

￿ Source Attn (dB):Value of Source attenuation, be-

 

 

tween 0 and ￿70 (calculated and displayed only).

 

 

￿ Drain Current Checkbox: When checked the

 

 

drain current is measured and power added effi-

 

 

ciency is calculated and displayed.

 

 

￿ PStop Level (dB):Provides the ability to set the

 

 

PStop value based on the level of gain compres-

 

 

sion. Drop down options include compression levels

 

 

of 1 dB through 10 dB in 1 dB increments, and

 

 

 

 

OFF. If OFF is selected, then the P Stop equals the

 

 

value entered in the “to” window above. If the se-

 

 

lected compression occurs, PStop for all subse-

 

 

quent power sweeps is reset to one increment be-

 

 

fore the Pin value where this compression level is

 

 

reached.
