One-Button Measurement Functions
Remote Command:
This parameter can send up to 10 values. The location in the list sent corresponds to the
range the value is associated with. Missing values are not permitted, for example, if you
want to change values 2 and 6, you must send all values up to 6. Subsequent values will
remain as they were.
[:SENSe]:HARMonics:RANGe[:LIST]:SWEep:TIME:AUTO OFF|ON|0|1 selects the mode.
[:SENSe]:HARMonics:RANGe[:LIST]:SWEep:TIME: <integer>
The query for this parameter will always return 10 values.
[:SENSe]:HARMonics:RANGe[:LIST]:SWEep:TIME:AUTO?
[:SENSe]:HARMonics:RANGe[:LIST]:SWEep:TIME?
5.16.6.7 Auto Fill Range Table
Auto Fill Range Table is used to automatically setup the range table based on the current
range center frequency and span. When selected, the current center frequency is taken as
the fundamental and the frequency in range one is set to this value. Each of the
subsequent range center frequency parameters are set to the appropriate integer multiple
of the fundamental frequency. The span for range one is set to that of the current range.
Each of the subsequent range span parameters are set to the appropriate integer multiple
of the fundamental span. This means that if the fundamental range is zero span, all the
ranges will be zero span. If the range span is zero,
Res BW, Video BW,andSweep Time are set
to the current base instrument settings. If the range span is non-zero, Res BW, Video BW,and
Sweep Time for all harmonics are set to the same settings as for the fundamental. Span is
set to zero for all harmonics and the fundamental.

5.16.7 Optimize Ref Level
Sets the input attenuator to optimize the robustness of the measurement, which is its
freedom from errors due to input compression.
NOTE There will always be a minimum of 2 dB of attenuation set to reduce the
