The allrounder

The Vector Signal Generator R&S® SMV03 is based on the successful analog Signal Generator R&S® SML03 and features the same excellent technical characteristics. It comprises an additional broadband I/Q modulator that is able to generate any digital signal in conjunction with an external I/Q source. The R&S® SMV03 is, therefore, a way of entering the wide field of automatic test systems as well as gaining access to applications such as R&D and service. When used together with the R&S® AMIQ and R&S® WinIQSIM™, the R&S® SMV03 can generate digital signals that meet any requirement.

In combination with the Arbitrary Waveform Generator R&S AMIQ the setup looks like:

Broadband I/Q modulator

Thanks to its wide RF bandwidth of 100 MHz, the R&S® SMV03 is optimally suited for future systems which require higher bandwidth tests, eg.W-LAN.

Frequency response of I/Q modulator (carrier frequency 1 GHz)

Wide output frequency range from 9 kHz to 3.3 GHz with 0.1 Hz resolution

With the wide frequency range many applications are covered and one instrument can be used in many different tasks.

High (+13 dBm) and precise output level (<0.5 dB)

R&S® SMV03 has plenty of power in reserve so level loss produced by the test setup can be easily compensated. Also its high level accuracy makes it ideal for use in larger test setups: Measurement uncertainty can be split into the contribution from the instrument and that introduced from the test setup. With a smaller uncertainty of the generator, greater tolerances can be allowed for the test setup. If the small level deviation of the analyzer is used to allow for higher DUT tolerances, the result will be a marked reduction in manufacturing rejects - an advantage that pays off immediately.

Interruption-free level setting by electronic attenuator

Many highly sophisticated electronic devices are very sensitive for overshoots which are coming up from interrupts in level variations. With the interruption-free level setting of the R&S® SMV03 by its electronic attenuator the device under test is save from such overshoots.

SSB phase noise typ. -128 dBc (f=1 GHz, 20 kHz carrier offset, 1 Hz measurement bandwidth)

Low-noise frequency synthesis ensures modulation of highest quality for reliable test signals.

Fast setting time for frequency and level

Due to the synthesizer concept the setting times are very low. This is an important feature which makes it ideal for the use in production where speed is of prime importance. And this is exactly one of the strong points of the R&S® SMV03, with a setting time lower than 12 ms when IQ modulation is switched on. Without IQ modulation the value is with 10 ms even lower.

Low cost of ownership with a 3-year calibration cycle

The three-year calibration intervals cuts costs and increase availability.

Compact size (only 2 HU)

Space is often at a premium in production. The compact size of the R&S SMV03 makes it ideal for use in such environments.

AM/FM/φM and optional Pulse modulation

Versatility

The R&S® SMV03 generates all kinds of I/Q-modulated signals using the integrated vector modulator. Owing to its wide I/Q bandwidth of 50 MHz, the R&S® SMV03 is also optimally suited for applications using high data rates such as WLAN standards. Signals to digital standards can be easily generated in conjunction with an external I/Q source like the Modulation Generator R&S® AMIQ (PD 0757.3970) and the associated R&S® WinIQSIM™ simulation software (PD 0758.0680).

The R&S® SMV03 therefore optimally meets production environment requirements.

Dimensions

The compact size (only 2 HU) makes the R&S® SMV03 ideal for use in production where space is often limited.

Speed

Speed is essential – especially in production. And this is exactly where the R&S® SMV03 shows what it can do with a frequency and level setting time of <10 ms.

Accuracy

Any measurement uncertainty has two components: the uncertainty due to the measuring instrument and that due to the rest of the test setup. The lower the level uncertainty of the vector signal generator, the greater the test setup tolerance that may be allowed. If greater tolerances can be allowed for the DUT because of the small level error of the R&S® SMV03, production rejects can be markedly reduced – an advantage that pays off immediately.

Reliability

A signal generator used in production must feature high reliability. The R&S® SMV03 meets this requirement, for example, through the use of a completely wear-free electronic attenuator.

Output level

In production test systems, the signal is routed to the DUT via switches and cables which introduce losses. This can be compensated for by the high output power of the R&S® SMV03.

Example: component test

Tests using digital signals are becoming increasingly important for checking the functions of individual components – especially at the component production stage. In this environment, the R&S® SMV03's I/Q modulator shows what it can do. Owing to its wide signal bandwidth of 50 MHz, it can generate a great variety of digital signals when an external I/Q source is used.

To obtain reliable information on component quality, high level accuracy and high output level repeatability are essential. The R&S® SMV03 fully meets these requirements owing to a maximum level uncertainty of <0.5 dB (at levels >–120 dBm) and high reproducibility.

Extremely short frequency and level setting times (<10 ms) allow fast measurements and make the R&S® SMV03 the ideal generator for production testing.
