Interface Operation 85
High Speed Operation
The 6000 instrument family has the capacity to operate at over 100 readings per
second when correctly configured. This section covers some useful information
concerning achieving the highest possible speed from these instruments.
Measurement Periods
The highest possible reading rates are obtained when only those inputs, which are
required to be high speed are configured with short measurement periods. Inputs that
are not required can be turned off, or set to an amplitude measurement period in
excess of 0.25 seconds. See the
MEAS command for details.
Frequency Measurement
Inputs which are not configured for use for fundamental frequency determination
should have their frequency measurement turned off. There is a significant speed
improvement when the fundamental frequency range covers a range of less than 2:1.
If harmonic measurements are not needed, or the fundamental frequency is well
known (to with 1%, e.g. line voltage), then the use of a fixed frequency fundamental
will achieve significant results. See the
FMEAS
and
FUND
commands for details.
Harmonic Measurement
Only enable a harmonic measurement in groups of inputs for which it is required.
The maximum range of harmonics should be limited and the
fundamental:
bandwidth ratio kept to the default values, if possible. If high frequencies are to be
measured, then a significant improvement in speed can be realized by only allowing
a single analysis per measurement period. See the
HARM command for further
details.
Interrogating Results
Read as many parameters at the same time as possible. This saves time in reducing
the transmission of new READ= commands, and their decode in the instrument.
The amount displayed on the front panel should be reduced to as little as possible
(less than four lines if possible) and any display line filters should be eliminated as
these are continuously updated whether displayed or not.
