3.2 Modulation Analysis Measurement
Range
Represents the amplitude of the largest sinusoidal signal that could be present
within the IF without being clipped by the ADC. For signals with high peak-to-
average ratios, the range may need to exceed the rms signal power by a significant
amount to avoid clipping.
This is a measurement global setting.
Remote
Command
[:SENSe]:POWer[:RF]:RANGe <real>
[:SENSe]:POWer[:RF]:RANGe?
Example
:POW:RANG 10 dBm
:POW:RANG?
Notes The MIN and MAX values are affected by the External Gain parameters, and by the Center Frequency
The hardware compensates for frequency response and alters the Range setting
Preset 0 dBm
State Saved Yes
Min/Max –/+100
Annotation Meas Bar
Adjust Range for Min Clipping
Sets the combination of attenuation and gain based on the current measured signal
level so that clipping will be at a minimum.
This is an "immediate action" function, that is, it executes once, when the key is
pressed.
This key does not appear in measurements that do not support this functionality.
Remote Command
[:SENSe]:POWer[:RF]:RANGe:OPTimize IMMediate
Notes Executing Adjust Range for Min Clipping initiates the measurement
Dependencies Does not appear in the Swept SA and Monitor Spectrum measurements
Pre-Adjust for Min Clipping
If this function is ON, it applies the adjustment described under Adjust Range For Min
Clipping each time a measurement restarts. Therefore, in Continuous measurement
mode, it only executes before the first measurement.
Remote Command
[:SENSe]:POWer[:RF]:RANGe:OPTimize:ATTenuation OFF | ON | ELECtrical |
