R&S SM300

Communication

Version 04

Service Manual SM300: 1147.1652.00

Instrument Part No SM300: 1147.1498.03

4.3 Communication

4.3.1 Internal Interface

Universal serial
bus (USB)

All internal communication (control PC, generator module, power supply) is
handled via USB.

USB switch

A switch is used to connect the host to the USB hub, which further splits the USB
to the measurement and power supply modules. This allows control of the
instrument either by means of the internal control PC or by an external PC.

Bus bandwidths

The bus bandwidths required by current applications are covered by the effective
6 Mbit/s to 8 Mbit/s value of the USB.

4.3.2 External Interfaces

Connect via USB

The instruments of the Smart Instruments Family 300 platform can be remote-
controlled by an external PC via USB.

Peripheral
devices

An additional USB port serves to connect peripheral devices (external keyboard,
storage medium, printer).
