Rohde & Schwarz SMJ100A Vector Signal Generator
The Rohde Schwarz SMJ100A is a multipurpose vector signal generator for research and development, production, and service. It combines a wideband I/Q modulator with an optional internal baseband generator so one instrument can produce standard compliant signals for digital communications as well as replay arbitrary waveforms. It was introduced in 2005 as a versatile mid range instrument with a large color display and a graphical user interface that shows the signal flow as a block diagram.
Key Features Rohde Schwarz SMJ100A
- Frequency range: from 100 kHz up to 3 GHz or 6 GHz depending on the RF option fitted (SMJ-B103 for 3 GHz, SMJ-B106 for 6 GHz)
- Wideband I/Q modulator: 200 MHz RF bandwidth and with the internal baseband generator signals up to 80 MHz bandwidth
- Excellent signal quality: typical SSB phase noise of -133 dBc (1 Hz bandwidth, 20 kHz offset, at 1 GHz), and typical ACLR of 69 dB for 3GPP FDD (test model 1, 64 DPCHs)
- Fast settings: frequency setting time under 2 ms, typically 1.5 ms
- Optional baseband generator: real time signal generation with a universal coder for digital standards such as GSM/EDGE, 3GPP FDD, and CDMA2000, plus support for newer standards such as WiMAX and LTE through software options
- Arbitrary waveform generator: options of 16, 64, or 128 Msample memory supported by R&S WinIQSIM2 simulation software
- Lower-cost ARB-only option: an optional ARB-only baseband generator as a cost saving alternative
- Easy to operate: a color SVGA (800 × 600) display with an intuitive GUI a block diagram of the signal flow, graphics for constellation, CCDF and I/Q diagrams, tooltips and a context sensitive help system
- Connectivity: IEEE 488.2 (GPIB), 100BaseT LAN, USB connectors (for keyboard, mouse, and memory stick), VGA output, and LXI class C compliance
- Digital baseband output option (SMJ-B18): a lossless digital I/Q connection to other Rohde & Schwarz instruments such as the AMU200A baseband generator and fading simulator
- Other signal types: options and software extend it to multicarrier CW, GPS, and DAB/T-DMB, among others
- Remote operation: desktop or VNC remote control
Typical Applications
- Receiver and component testing for wireless standards such as GSM/EDGE, 3GPP, CDMA2000, WiMAX and LTE
- Amplifier and transmitter characterization, including ACLR measurements
- Wideband modulation and arbitrary waveform replay
- Broadcast and navigation signal simulation (DAB, GPS)
- R&D, production test and calibration labs
Why Choose It
The Rohde Schwarz SMJ100A offers strong signal quality and a flexible architecture so a single generator can handle many standards and arbitrary waveforms. Its modular options let you start with the RF range and baseband features you need now and add more as requirements grow.
