Measurement Tutorial
When auto-range is enabled, trigger level accuracy is increased, latency is increased, and sensitivity
l
is decreased as the aperture or NPLC setting is increased.
When auto-range is enabled, trigger level accuracy is increased, latency is increased, and sensitivity
l
is decreased if autozero is enabled.
When auto-range is enabled, range changes may be made while waiting for the trigger crossing
l
which can cause additional latency/uncertainty.
4-wire resistance and temperature considerations
Trigger level accuracy is increased, latency is increased, and sensitivity is decreased as aperture or
l
NPLC is increased.
Fixed range (only available for resistance) eliminates uncertainties (due to range change) in trigger
l
latency.
AC voltage and AC current considerations
Trigger latency is increased, and sensitivity is decreased as filter bandwidth is increased.
l
Trigger latency can be controlled by trigger delay setting.
l
Fixed range eliminates uncertainties (due to range change) in trigger latency.
l
Autorange uncertainties become worse as filter bandwidth is increased.
l
Frequency and period considerations
Trigger level accuracy is increased, latency is increased, and sensitivity is decreased as gate time is
l
increased.
Fixed voltage range eliminates uncertainties (due to range change) in trigger latency.
