Average Commands 5-71
SR785 Dynamic Signal Analyzer
Average Commands (Octave)
OTYP (?) d {, i}
The OTYP command sets (queries) the Octave Averaging Type for display d.
The parameter i selects Linear Time (0), Exponential Time (1), Peak Hold (2) or
Equal Confidence (3).
For 1 Channel octave analysis, the set command requires d=2.
This command is valid only when the Measurement Group is Octave. The set
command requires display d to be Live.
OTIM (?) d {, x} <ks, [s], ms>
The OTIM command sets (queries) the Octave Averaging Time for display d.
The parameter x is the averaging time from 0.004 to 1000 seconds.
For 1 Channel octave analysis, the set command requires d=2.
This command is valid only when the Measurement Group is Octave. The set
command requires display d to be Live.
NAVG ? d
The NAVG command queries the amount of averaging completed for display d.
The returned value is the amount of averaging completed in 4 ms increments. For
example, a completed linear average of 1 second returns 250.
For exponential averaging, the returned value is the actual averaging completed
and eventually exceeds the Octave Average Time.
This command is valid in FFT and Octave Measurement Group.
OCNF (?) d {, i}
The OCNF command sets (queries) the Octave Averaging Confidence Level for
display d. The parameter i selects 0.125 dB (0), 0.25 dB (1), 0.5 dB (2), 1.0 dB
(3) or 2.0 dB (4).
For 1 Channel octave analysis, the set command requires d=2.
This command is valid only when the Measurement Group is Octave. The set
command requires display d to be Live.
OIMP (?) d {, i}
The OIMP command sets (queries) the Octave Power Bin for display d. The
parameter i selects Total (0), Impulse (1), L (2) or Peak (3).
Peak power is not allowed if the Averaging Type is not Peak Hold.
Peak power is automatically selected if the Averaging Type is Peak Hold. Use
the OTYP command to set Peak Hold averaging.
