is used to set the frequency for power sweep and CW time
sweep modes. If the instrument is not in either of these
two modes, it is automatically switched into CW time
mode.
turns on a sweep mode similar to an oscilloscope. The
analyzer is set to a single frequency, and the data is
displayed versus time. The frequency of the CW time
sweep is set with
CW FREQ
this math function ratios channels 1 and 2, and puts the
results in the channel 2 data array. Both channels must be
on and have the same number of points. Refer to the
"Making Measurements" chapter in the user's guide for
information on how to use this function to make gain
compression measurements.
sets the source tune DAC for frequencies above 20.05 GHz.
sets the source tune DAC for frequencies below 2.55 GHz.
sets the source tune DAC for frequencies above 2.55 GHz
and below 20.05 GHz. (ES only.)
displays both the current data and memory traces.
specifies whether or not to store the error-corrected data
on disk with the instrument state.
divides the data by the memory, normalizing the data to
the memory, and displays the result. This is useful for
ratio comparison of two traces, for instance in
measurements of gain or attenuation.
subtracts the memory from the data. The vector
subtraction is performed on the complex data. This is
appropriate for storing a measured vector error, for
example directivity, and later subtracting it from the
device measurement.
