Rohde and Schwarz SMC100A - Signal Generator (Requires Frequency Option)

The analog R&S SMC100A sets new standards for attractively-priced signal generators. It has the smallest size and the best price/performance ratio in its class.

The R&S SMC100A offers outstanding signal quality at an attractive price. It covers the frequency range from 9 kHz to 1.1 GHz or 3.2 GHz. Output power is typ. > +17 dBm. All important functions (AM/FM/φM/pulse modulation) are already integrated in the instrument. This makes the R&S SMC100A signal generator a flexible and versatile instrument.

Total cost of ownership is an important factor when purchasing a measuring instrument. The R&S SMC100A, apart from offering a low initial cost, also boasts low service costs since users can replace defective modules on their own and verify the level repeatability and accuracy by using the R&S NRP-Z91/NRP-Z92 power sensors.

These outstanding features make the R&S SMC100A ideally suited for use in service and maintenance labs. Due to its small dimensions and lightweight design, the R&S SMC100A is also the perfect choice for field applications or training and education environments.

Several versions available

The SMC100A is available in several packages with a 1.1 or 3.2 GHz maximum frequency, as well as with or without the OCXO reference oscillator option (SMC-B1). Please note, the SMC100A must be ordered with a factory installed frequency option. The base model (SMC100A / 1411.4002.02) does not include the frequency option, the other four items shown below have either a 1.1 or 3.2 GHz option installed.

High performance at an attractive price

The R&S SMC100A features an unbeatable price/performance ratio. Although the R&S SMC100A is positioned in the economy price segment, customers nevertheless benefit from excellent performance and tried-and-tested Rohde&Schwarz quality, which is marked by precision workmanship, high reliability and ease of operation.

Due to its low SSB phase noise, low wideband noise and excellent nonharmonic suppression, the R&S SMC100A is suitable for all applications that require spectrally pure signals. This ensures that the performance of the device under test is measured and not that of the test instrument.

Flexible and universal all-purpose signal generator

The R&S SMC100A is a flexible, analog signal generator that can be universally deployed for a variety of applications.

Full set of standard features

The user benefits from an instrument that contains all important functions right out of the box. The R&S SMC100A is fully equipped in its standard configuration. The analog AM, FM, φM and pulse modulation modes are integrated in the instrument as standard. An internal modulation and pulse generator supplies the required modulation signals. Special options are not required.

Easy replacement of legacy signal generators through remote control emulation

When test systems include legacy signal generators that are no longer manufactured or can no longer be repaired, switching to other types of generators is usually a costly exercise. This frequently results in the time consuming task of modifying the remote control software, provided that the source code is still available. Since the R&S SMC100A has remote control emulation modes for a wide variety of signal generators, it can very easily replace old instruments. By simply setting the remote control emulation mode on the R&S SMC100A, it immediately understands the bulk of the command sets for the instrument being emulated.

High reliability through overvoltage protection and electronic attenuator

Overvoltage protection, which is integrated as a standard feature, constantly protects the R&S SMC100A from inadvertent reverse power surges. This prevents instrument downtime.

The electronic attenuator also improves the reliability of the R&S SMC100A since the electronic switch will not wear out even if applications require frequent level switching.

Space-saving operation due to small dimensions

The R&S SMC100A is the smallest analog signal generator in its class. With a width of only ½ × 19", two instruments can be installed side-by-side in a single 19" rack. The R&S SMC100A is a mere two rack units high, meaning it can still be rack-mounted in installations where space is already at a premium.

Minimized total cost of ownership

The easy-to-use error diagnostics and the option for users to replace defective modules on their own reduces instrument downtimes to a minimum. This advantage and the low service costs contribute to keeping the signal generator's total cost of ownership extremely low.

Apart from the initial cost, the costs for repairs and calibration must also be taken into consideration when calculating the total cost of ownership of a measuring instrument.

The long calibration interval of three years saves costs even after the instrument has been purchased.

In case of instrument malfunction, repairs can be carried out by a certified Rohde&Schwarz service center or users can rectify the fault on their own by replacing defective components with pre-calibrated replacement modules.

The modular design of the R&S SMC100A (RF board, mainboard, front unit and power supply) enables the rapid replacement of modules. An integrated software diagnostics routine identifies and displays the defective module. In case of malfunction, the module can be replaced in around 20 minutes.

To additionally optimize level accuracy after servicing, a new level correction can be performed fully automatically by means of an R&S NRP-Zxx power sensor that is connected to the R&S SMC100A.

Ideal tool for many application fields

Research and education

Due to its low initial cost and the aforementioned features, the R&S SMC100A is also an ideal signal source for training and education applications at schools or universities. The generator is flexible enough for use in RF experiments.

Field use

The small and lightweight design (3.9 kg) makes the R&S SMC100A the signal generator of choice for applications in the field. Users can simply transport the instrument to any location and carry out accurate and repeatable measurements. The R&S NRP-Zxx USB power sensors can also be connected to the R&S SMC100A using USB adapters. This enables users to perform simple and precise power measurements without having to carry around an additional power meter base unit.

Secure areas

A sanitizing routine can be initiated through the menu on the R&S SMC100A. This allows the deletion of all security critical instrument settings and user data. Afterwards, the instrument can be removed from secure areas within the aerospace and defense sectors without risk. Users can also deactivate the USB and LAN interfaces.
