VectorStar™ MS464xB Series Microwave Vector Network Analyzer Programming Manual : SCPI Commands : :SENSe{1-16}:FREQuency Subsystem
 
:SENSe{1-16}:FREQuency Subsystem
The :SENSe{1-16}:FREQuency subsystem commands control the various instrument frequencies on a channel-by-channel basis.
Channel and Sweep Subsystems
Related channel and sweep configuration and control subsystems are:
• :SENSe{1-16}:AVERage Subsystem
• :SENSe{1-16}:FSEGMent Subsystem
• :SENSe{1-16}:SPUR Subsystem
• :SENSe{1-16}:SWEep Subsystem
Frequency Limits
The frequency limits for the :SENSe{1-16}:FREQuency subsystem and other commands are described in detail in General Information, Minimum/Maximum Instrument Frequency and Related Parameters and the related tables in that section. In general, the frequency default values and limits are affected by two factors:
• Instrument Model Number
• Installed Options (Option 70)
