:ACQuire:TYPE
(see page 798)
Command Syntax
:ACQuire:TYPE <type>
<type> ::= {NORMal | AVERage | HRESolution | PEAK}
The :ACQuire:TYPE command selects the type of data acquisition that is to
take place. The acquisition types are: NORMal, AVERage, HRESolution, and
PEAK.
• The :ACQuire:TYPE NORMal command sets the oscilloscope in the
normal mode.
• The :ACQuire:TYPE AVERage command sets the oscilloscope in the
averaging mode. You can set the count by sending the :ACQuire:COUNt
command followed by the number of averages. In this mode, the value
for averages is an integer from 1 to 65536. The COUNt value determines
the number of averages that must be acquired.
Setting the :ACQuire:TYPE to AVERage automatically sets
:ACQuire:MODE to ETIMe (equivalent time sampling).
The AVERage type is not available when in segmented memory mode
(:ACQuire:MODE SEGMented).
• The :ACQuire:TYPE HRESolution command sets the oscilloscope in the
high- resolution mode (also known as smoothing). This mode is used to
reduce noise at slower sweep speeds where the digitizer samples faster
than needed to fill memory for the displayed time range.
For example, if the digitizer samples at 200 MSa/s, but the effective
sample rate is 1 MSa/s (because of a slower sweep speed), only 1 out of
every 200 samples needs to be stored. Instead of storing one sample
(and throwing others away), the 200 samples are averaged together to
provide the value for one display point. The slower the sweep speed,
the greater the number of samples that are averaged together for each
display point.
• The :ACQuire:TYPE PEAK command sets the oscilloscope in the peak
detect mode. In this mode, :ACQuire:COUNt has no meaning.
Query Syntax
:ACQuire:TYPE?
The :ACQuire:TYPE? query returns the current acquisition type.
Return Format
<acq_type><NL>
<acq_type> ::= {NORM | AVER | HRES | PEAK}
NOTE
The obsolete command ACQuire:TYPE:REALtime is functionally equivalent to sending
ACQuire:MODE RTIME; TYPE NORMal.
