3.6 Modulation Analysis Measurement
54 Mbits/s RMS EVM
This parameter is available when Radio Std is 802.11a/b/g/j/p OFDM 20 MHz or
802.11g DSSS-OFDM.
Sets 54 Mbits/s RMS EVM limit to warn you if the measured average RMS EVM
value exceeds a limit.
Remote Command
:CALCulate:EVM:LIMit:RMS:M54 <rel_ampl>
:CALCulate:EVM:LIMit:RMS:M54?
Example
:CALC:EVM:LIM:RMS:M54 -25
:CALC:EVM:LIM:RMS:M954
Notes This limit value is used in 802.11a/g/j/p (OFDM 20M), 801.11g (DSSS-OFDM)
Preset -25.00 dB
State Saved Saved in instrument state
Min -1000.00
Max 0.00
Freq Error
Sets a frequency error limit to warn you if the measured maximum frequency error
value exceeds the limit.
Remote
Command
:CALCulate:EVM:LIMit:FERRor <real>
:CALCulate:EVM:LIMit:FERRor ?
Example
:CALC:EVM:LIM:FERR 15
:CALC:EVM:LIM:FERR?
Couplings If Radio Std is 802.11n 802.11ax or 802.11be and Center Frequency for 5GHz band, freq error limit will
be coupled to 20.0ppm
Preset If Radio Std is 802.11a/g/j/p (OFDM), 802.11ac, or 802.11ah: 20.00 ppm
If Radio Std is 802.11b/g (DSSS/CCK/PBCC), 801.11g (DSSS-OFDM): 25.00 ppm
If Radio Std is 802.11n, 802.11af, 802.11ax, 802.11be for 2.4G Band: 25.0ppm
State Saved Saved in instrument state
Min 0
Max 500 ppm
Clock Error
Sets a clock error limit to warn you if the measured maximum clock error value
exceeds the limit.
