Attribute Summary:
Description:
This command automatically adjusts the input range. Two types of autorange are available; up/down
(VOLT:RANG:AUTO:DIR EITHer) and up only (VOLT:RANG:AUTO:DIR UP). The default selection
is up/down.
If up/down autorange is selected, the analyzer searches for the best input range at the start of a
measurement. If the analyzer detects an overload condition, the analyzer steps the input up through
successive range values (+2 dB increments) until the input is no longer in an overload condition. If the
analyzer detects that the input signal has dropped below half the range value, the analyzer steps the input
down in -2 dB increments until the input has returned to half range.
If up only autorange is selected, the analyzer selects the lowest input range at the start of a measurement.
If the analyzer detects an overload condition, the analyzer steps the input up through successive range
values (+2 dB increments) until the input is no longer in an overload condition. The analyzer never
adjusts the range downward in response to a decrease in signal amplitude. If the range is too large for the
current input signal, send VOLT[1|2|3|4]:RANG:AUTO ON to restart autorange.
If you use this command for a swept sine measurement, the analyzer adjusts the input range upward or
downward at each measurement point, depending on the signal level at the measurement point.
Note
The analyzer does not autorange during a time capture or during an averaged
measurement.
