Burst Power Meas Offset
To measure power of a specified period, this parameter specifies the measuring
start time of a burst.
Remote Command
[:SENSe]:EVM:TIME:BPOWer:OFFSet <time>
[:SENSe]:EVM:TIME:BPOWer:OFFSet?
Example
:EVM:TIME:BPOW:OFFS 1us
:EVM:TIME:BPOW:OFFS?
Dependencies Only available for 11n/ac/ax/be and 11agjp when radio std detection is auto
Preset
1us
State Saved Saved in instrument state
Min/Max -/+3 ms
Burst Power Meas Length
To measure power of a specified period, this parameter specifies the measurement
length.
Remote Command
[:SENSe]:EVM:TIME:BPOWer:LENGth <time>
[:SENSe]:EVM:TIME:BPOWer:LENGth?
Example
:EVM:TIME:BPOW:LENG 10us
:EVM:TIME:BPOW:LENG?
Dependencies Only available for 11n/ac/ax/be and 11agjp when Radio Std detection is auto
Preset
20us
State Saved Saved in instrument state
Min/Max 1us/6 ms
3.7.9.4 Sync
Configure the synchronization parameters.
Symbol Timing Adjust
The extended OFDM symbol time period (T
S
) consists of a guard interval (T
GI
) plus a
"useful symbol time period" (T
FFT
).
This parameter adjusts the demodulation start time to begin earlier within each
extended symbol time. The shift is specified as a percentage of the T
FFT
length.
