POWER SWEEP, TWO TONE | OPERATIONS, MEASUREMENT |
Multiple Frequency | Procedure. |
Power Sweep |
|
Measurement Type: Drop down options. Set to “Multi Freq Power Sweep ” for this test.
Main Tone (MHz): CW Frequency setting for source 1. The user may set a lower tone and upper tone. The software will sweep three frequencies (the two input plus one between) and the RF input power to produce the display data.
Offset (kHz): Offset frequency for Source 2 (Source 2 will be set to Main Tone + Offset).
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.
