NOTE
• The range and resolution of the frequency, pulse width, and duty cycle
measurement follows the configuration of the AC voltage or AC current
measurement (dependant on the path chosen).
• The U3606A will automatically select a suitable range for AC voltage
and AC current measurements by default (autoranging). To manually
select a range, see “Selecting a Range” on page 54 for more
information.
• The U3606A resolution is set to 5½ digits by default. To change the
resolution, see “Setting the Resolution” on page 55 for more
information.
CAUTION
If the frequency signal measured is below 20 Hz, you must manually
set the range of the AC voltage or AC current measurement to acquire
a stable reading.
To manually select a range, see “Selecting a Range” on
page 54
for more information.
