Description

120 OUTPUT 723;"MEASURE SA;"

The MEASURE command determines what kind of measurements the modular measurement system makes.

Argument

De￿nition

SA

Activates spectrum analysis, where all amplitude units are

 

speci￿ed in absolute values determined by:

 

￿

Amplitude units (AUNITS)

 

￿

Reference level (RL)

 

￿

Reference-level o￿set (ROFFSET)

 

￿

Logarithm scale (LG)

 

￿

Linear scale (LN)

 

￿

Amplitude correction (AMPCOR)

SR

Activates stimulus-response measurements where amplitude

 

units are speci￿ed relative to a reference level of 0 dB when

 

the A-minus-B or A-minus-C commands, AMB or AMC, are

 

executed. During relative-amplitude mode, the following

 

parameters are in dB:

 

￿

Trace data (TRA, TRB, TRC)

 

￿

Trace data conversions (AMPU and MEASU)
