Agilent E6432A Microwave Synthesizer Users Guide 4-177
HPE6432_SetFreqAlcAtten
ViStatus HPE6432_SetFreqAlcAtten (ViSession
instrumentHandle, ViReal64 frequency, ViReal64 alcPower,
ViUInt16 attenuation);
Purpose
This function sets the output frequency, ALC power level, and
attenuation to specified values. An attenuation value must still be
specified even if the synthesizer does not contain a step attenuator
(Option 1E1).
This function allows a single operation to set both frequency and power
so that the synthesizer can be rapidly moved from point to point in a
system environment without using the list mode.
NOTE When in high band, ALC switching speed can be maximized with
minimum settling and dwell times while using the fastest interface and
computer available. Examples are shown below of the average ALC
switching times required to set the ALC using different interfaces and
different speed computers.

Variable Type ViSession
This is the ViSession handle that is obtained from the Initialize
function. The instrumentHandle identifies a particular instrument
session.
