Instrument Addressing
The synthesizer has a factory preset logical address of FF; this value
allows the synthesizer to be “auto-configured” where the Slot 0 device
assigns an address based on address availability.
• When using the Soft Front Panel, view the assigned logical address
on the top bar of the dialog box.
• When using a programmable interface, refer to “Determining the
Logical Address of the Synthesizer When Set to Be
Auto-Configured (FF)” on page 4-8.
• When opening an instrument session using the HPE6432_init
function, an instrument address must be specified for the function’s
ViRsrc InstrDesc parameter. The instrument address is based on the
logical address and on the communication interface between the
computer/controller and the instrument.
The address strings for various interface are given below. In each
address, take note of the following:
• ‘INSTR’ is an Agilent Technologies VISA resource type
• VXI0 => could be VXI0..VXI7
• 210 => could be any available address from 1..254
