cycle of the entered base ripple frequency. All harmonic data is measured
over the longer of 5ms (rounded upwards to the nearest integer number of
cycles) or four cycles of the entered base ripple frequency. Frequency is
not measured. Signals have a fixed-corner, low-pass filter applied with a
corner frequency equal to 200 times the entered base ripple frequency
Note:
When you enable autorange and a downrange is required, the
analyzer downranges at the rate of 20ms per range. DC is the
recommended selection when making DC measurements.
USER SET
This selection brings up a menu choice in the Ch1 MEASUREMENT
CONFIGURATION that allows you to directly select USER SET
MEASUREMENT configuration parameters, which are automatically set
for the other selections. Refer to USER SET MEASUREMENT below.
Note:
This USER SET selection is not recommended for inexperienced
users.
LOW FREQ (0.5-20Hz)
Configures the analyzer to make optimal signal measurements at
frequencies less than line frequency, in the range 0.5 to 20Hz. To
accomplish this, the analyzer –
1) Synchronizes on the voltage waveform with frequencies in the range
of 0.5Hz to 20Hz; and
2) Tracks the input signals using a fixed low-pass filter where the filter
corner frequency is set to maintain better than 5% accuracy at 10kHz.
Note:
When you enable autoranging and a downrange is required, the
analyzer downranges at the rate of 10s per range. The LOW FREQ (0.1-
100Hz) selection is recommended when making low frequency
measurements. LOW FREQ is not recommended for line measurements.
LOW FREQ (0.02-5Hz)
Configures the analyzer to make optimal signal measurements at
frequencies less than line frequency, in the range 0.02 to 5Hz. To
accomplish this, the analyzer –
1) Synchronizes on the voltage waveform with frequencies in the range
of 0.02Hz to 5Hz; and
