Improving Measurement Speed - Agilent Technologies ESA Series User's/Programmer's Reference

Improving Measurement Speed

There are a number of things you can do in your programs to make them run faster:
"Turn off the display updates"
"Use binary data format instead of ASCII"
"Minimize the number of GPIB transactions."
"Avoid unnecessary use of *RST."
"Minimize DUT/instrument setup changes."
There are additional things you can do to run faster if you are using a measurement
personality option (i.e. instrument Modes other than the standard Spectrum
Analysis Mode). The following applies only to a specific option mode:
"Using an Option Mode: Minimize the number of GPIB transactions."

Turn off the display updates
:DISPlay:ENABle OFF turns off the display. Updating the display slows down
the measurement. For remote testing, since the computer is processing the data
rather than a person, there is no need to display the data on the analyzer screen.
Disable auto alignment
:CALibration:AUTO OFF disables the automatic alignment process of the
instrument. Automatic alignment processing occurs at the end of each sweep. In a
stable operating environment, automatic alignment consumes very little instrument
resources. However, in a high throughput application, any demand upon
instrument resources affects measurement update rate.
NOTE When auto alignment is off, the
periodically. Refer to the appropriate "Specifications and Characteristics" chapter
in the Agilent Technologies ESA Spectrum Analyzers Specifications Guide - E
Series or Agilent Technologies ESA Spectrum Analyzers Specifications Guide - L
Series for more information on how often to perform
alignment is off.
Use a fixed IF Gain range
In applications where narrow resolution bandwidths (< 1 kHz) are required and a
high dynamic range is not required,
:DISPlay:WINDow:TRACe:Y[SCALe]:LOG:RANGe:AUTO OFF disables auto
ranging and results in increased measurement update rate.
