Remote Operation (USBTMC)
The Product rear-panel USB 2.0 type B port is a fully-programmable USBTMC interface that meets the
USBTMC-USB488 interface standard and supplemental IEEE-488.2 standard. Use the USBTMC
command set. See the 5560A/5550A/5540A Remote Programmers Manual at www.flukecal.com
for a
discussion of the commands available for USBTMC operation.
Remote Operation (Ethernet)
The Product rear-panel Integrated 10/100/1000BASE-T Ethernet port is for network connection remote
control of the Calibrator and complies with supplemental IEEE-488.2 standard. The Ethernet port
connects a host PC to the Product. To send commands to the Product, enter commands from a telnet
session running on the host computer. See the 5560A/5550A/5540A Remote Programmers Manual at
www.flukecal.com
for a discussion of the Ethernet commands available for Ethernet operation.

Theory of Operation
System Architecture
The Product architecture consists of two systems:
• An out-guard system that is earth referenced and contains all digital control, user interface (UI), and
remote interfaces.
• An in-guard system with all precision analog circuitry enclosed in a guard box that is galvanically
isolated.
Out-guard
The out-guard system features:
• Touchscreen display
• Front-panel keypad A2
• A13 interconnect
• A11 out-guard motherboard
• A9 controller.
See the sections below for these individual assemblies.
