10 Spectrum Emission Mask Measurement
AMPTD Y Scale
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 fair amount to avoid clipping.

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.)

Initial S/W Revision A.12.50
Adjust Range For Min Clip
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 is grayed out in measurements that do not support this functionality.

Pre-Adjust for Min Clip
If this function is on, it does the adjustment described under Adjust Range For Min Clip each time a
measurement restarts. Therefore, in Continuous measurement mode, it only executes before the first
measurement.
