Improving Measurement Speed
Avoid unnecessary use of *RST.
Remember that *RST presets all the measurements and settings to their factory
defaults and my also change the mode. This forces you to reset the measurement
settings of the analyzer even if they use similar mode setup or measurement
settings. See
Minimize DUT/instrument setup changes. below.
Minimize DUT/instrument setup changes.
• Some instrument setup parameters are common to multiple measurements. You
should look at your measurement process with a focus on minimizing setup
changes. If your test process involves nested loops, make sure that the
inner-most loop is the fastest. Also, check if the loops could be nested in a
different order to reduce the number of parameter changes as you step through
the test.
• Are you are using the pre-configured Measurements (
MEASURE
key)?
Remember that if you have already set your Meas Setup parameters for a
measurement, and you want to make another one of these measurements later,
use READ:<meas>?. The MEASure:<meas>?. command resets all the settings
to the defaults, while READ changes back to that measurement without
changing the setup parameters from the previous use.
• Are you are using the pre-configured Measurements (
MEASURE
key)? Also
remember that Mode Setup parameters remain constant across all the
measurements (such as: center/channel frequency, amplitude, radio standard,
input selection, trigger setup). You don’t have to re-initialize them each time
you change to a different measurement.
