Optimizing the N432A Performance

This section discusses the factors that influence the speed of operation of the
N432A.
The following factors are those which have the greatest effect upon measurement
speed (in no particular order):
– Trigger mode (for example, free run, triggered free run, or single shot)
– Output format: ASCii or REAL
– Measurement unit
– Command used to take a measurement
The following paragraphs provide a brief description of the above factors and how
they are controlled from SCPI.

Trigger mode

The N432A has a flexible triggering system. For simplicity, it can be described as
having three modes:
– Free Run: When the N432A is in the free run mode, it continuously takes
– Triggered Free Run: When the N432A is in the triggered free run or continuous
– Single Shot: When the N432A is in the single shot mode, it takes a new
