Multiple Frequency
Power Sweep
Power Sweep
Procedure.
n
Measurement Type: Drop down options. Set to
“Multi Freq Power Sweep ” for this test.
n
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.
tone. The software will sweep three frequencies
(the two input plus one between) and the RF input
power to produce the display data.
n
Offset (kHz): Offset frequency for Source 2
(Source 2 will be set to Main Tone + Offset).
n
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.

n
Data Points: Number of data points in power
sweep.
n
Increment Power (dBm): Value to increment
power for each data point (calculated and dis-
played only).
played only).
n
Source Attn (dB):Value of Source attenuation, be-
tween 0 and
-70 (calculated and displayed only).
n
Drain Current Checkbox: When checked the
drain current is measured and power added effi-
ciency is calculated and displayed.
ciency is calculated and displayed.
n
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 P
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 P
in
value where this compression level is
reached.
