Keysight x-series Instruction Manual

3 Short-Range Comms & IoT Mode
3.7 ACP Measurement
FAST
Provides the same method as the Integration BW method, but is optimized for speed to measure a W-
CDMA signal
SA Mode with CDMA2K radio standard selected:
Provides faster measurement using the FFT method with a limited parameter flexibility. When this is
selected, CDMA2K preset offsets are given and control of the following are unavailable:
–
BW menu
–
Sweep/Control menu except Pause/Resume
–
Trace/Detector menu
–
Carrier Setup, Offset Limit, RRC Weighting, Filter Alpha, and Noise Correction in Meas Setup menu
Fast Power
FPOWer
(Option FP2
required)
This provides faster measurement using the Hardware accelerated FFT method with a limited parameter
flexibility. When this is selected, the following parameters are not available:
–
Points and Auto Sweep Points under Sweep
–
When changing Meas Method to Fast Power, Auto Sweep Points is turned on and grayed-out
(Sweep Points will change according to the Fast Power setting)
–
When returning Meas Method to any setting other than Fast Power, Auto Sweep Points stays on
and becomes available (Sweep Points will change according to the auto sweep points calculation
algorithm)
–
Trace Type, Restart Averaging and View/Blank under Trace when Select Trace is Trace 2 or Trace3
–
Span under Frequency
–
Res BW, Video BW, Filter Type and Filter BW of Offset > Advanced dialog of Carr/Offset/Limits Config
control under Meas Setup
–
For Trigger, only Free Run, External 1 and External 2 are supported
When in microwave frequency and measurement span is > 40MHz, RF preselector must be turned off
Remote Command
[:SENSe]:ACPower:METHod IBW | IBWRange | FAST | RBW | FPOWer
[:SENSe]:ACPower:METHod?
Example
:ACP:METH IBW
:ACP:METH?
Notes FAST mode is only supported for WCDMA and C2K signals. You must be in WCDMA or SA Modes,
with 3GPP WCDMA or CDMA2K radio standard. Otherwise, a setting conflict error message is
reported
MSR, LTEAFDD, LTEATDD and 5G NR Modes support only Integration BW, Filtered IBW and Fast
Power methods
Dependencies When RBW, FAST or FPOWer is selected, Gate function is not available. If you try to turn GateON
while Meas Method is RBW, FAST or FPOWer, an error is generated
When Gate function is ON, RBW, FAST and FPOWer are not available. If you try to change Meas
Method to RBW, FAST or FPOWer, an error is generated
VXT Models M9420A/10A/11A support only the Integration BW method
