The Rohde & Schwarz SMJ100A is a vector signal generator built around an I/Q modulator with 200 MHz RF bandwidth. It pairs a color SVGA display of 800 x 600 pixels with a graphical user interface that shows the signal flow as a block diagram, a built-in transient recorder for viewing baseband signals, and a context-sensitive help system. A high-stability reference oscillator is included as standard.

The instrument supports generation of a broad span of digital communication standards, including EUTRA/LTE, WiMAX (IEEE 802.16-2004/Corr1-2005, 802.16e-2005, and WiBro), 3GPP FDD with HSDPA and HSUPA, WLAN (IEEE 802.11a, b, g, and n), and GSM/EDGE with modulation changes from slot to slot. Very short frequency and level setting times together with RF List mode and multisegment waveforms suit it to production use.

ValueTronics stocks and holds its own inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received from the manufacturer. Holding the inventory ourselves means the instrument you order is on our shelves and ready to move.

> **Important:** Maximum permissible RF power into the output for f > 1 MHz: 50 W (1 MHz <= f <= 3 GHz) and 10 W (f > 3 GHz). Maximum permissible DC back-feed from a >=50 Ohm source: 50 V.

> **Important:** The base unit can only be ordered with an R&S SMJ-B10x frequency option (R&S SMJ-B103 up to 3 GHz or R&S SMJ-B106 up to 6 GHz).

> **Important:** The R&S SMJ-B13 Baseband Main Module must be installed for the I/Q baseband generator options (R&S SMJ-B9/-B10/-B11/-B50/-B51) and for the AWGN (R&S SMJ-K62) option.

> **Important:** Installation of software that is not authorized by Rohde & Schwarz for use on the R&S SMJ100A, or installation of antivirus software, can deteriorate the setting time performance.

> **Important:** The instrument complies with EN 55011 class A emission requirements (industrial environments); it may not be operated in residential, commercial and business areas or in small-size companies unless additional measures are taken to ensure compliance with EN 61000-6-3.

> **Important:** Functional specifications of the digital standard options (R&S SMJ-K40 to -K61) and the external-PC-software options (R&S SMJ-K5/-K6/-K8) are described in the separate Digital Standards data sheet (PD 5213.9434.22); R&S WinIQSIM2 and R&S WinIQSIM each require an external PC.

> Usage tip: the optional digital baseband output (R&S SMJ-B18) provides a lossless digital I/Q connection to the digital I/Q input of other Rohde & Schwarz instruments such as the R&S AMU200A baseband signal generator and fading simulator.
