3 Spectrum Analyzer Mode
3.7 Burst Power Measurement
[:SENSe]:POWer[:RF]:RANGe:OPTimize:ATTenuation?
Notes Because there is no attenuator control available in these models, the control displays only ON and
OFF choices. However, for SCPI compatibility with other platforms, all three parameters
(ELECtrical, COMBined, and ON) are honored and all are mapped to ELECtrical, so if any of
these three parameters is sent, a subsequent query will return ELEC
Dependencies Does not appear in the Swept SA and Monitor Spectrum measurements
Preset OFF for Swept SA measurement; ON for all other measurements that support Pre-Adjust for Min
Clipping
State Saved Saved in instrument state
Adjustment Algorithm
The algorithm for the adjustment is documented below:
Peak-to-Average Ratio
Used with "Range (Non-attenuator models)" on page 1975 to optimize the level
control in the instrument. The value is the ratio, in dB, of the peak power to the
average power of the signal to be measured. A ratio of 0 should be used for
sinusoidal signals; for 802.11g OFDM signals use 9dB.
All Modes show the current value of Peak-to-Average ratio on the control. However,
some Modes do not permit changing the value. In these situations, the control is
grayed-out.
Remote Command
[:SENSe]:POWer[:RF]:RANGe:PARatio <real>
[:SENSe]:POWer[:RF]:RANGe:PARatio?
Example
:POW:RANG:PAR 12 dB
Notes In some Modes, this parameter is read-only; meaning the value will appear on the control and query
