ROHDE & SCHWARZ SMBV100A Vector Signal Generator Firmware 3.20.281.28.7 Description

New Functionality

- Custom Digital Modulation: Support of low symbol rates down to 50 Hz with internal clock. 

Known Issues

- Absolute Power issue with DVB when toggling the digital standard state without toggling afterwards the RF state. Similar but minor issues are observed with other digital standards 
- Rarely the connection on the Digital Interface cannot be established in the SMBV. This is usually solved by reconnecting and checking the connection state in the SMBV  
- XM-Radio: The physical layer mode Terrestrial A and Terrestrial B does not work. 
- The synchronization of two SMBV100A using the master/slave setup with different baseband boards revisions (with different board revisions , e.g. 1407.7000 and 1407.7046, can be seen in Setup/System/Hardware Config) can’t be done automatically. For synchronization an external calibration with an oscilloscope is required. On the other hand, when having the same baseband board revisions on the two SMBV100A automatic baseband synchronization is supported as before.

About Device Firmware:

Applying a newer firmware version than the one already installed on your unit can bring various enhancements, include workarounds for diverse problems encountered by the device, and improve or add newly developed features.

On the other hand, downgrading the firmware version can recover the device’s functionality in the event of a software update either turning up faulty or causing the unit’s overall performance to drop. However, bear in mind that applying an older firmware isn’t recommended and might not always be possible.

When it comes to the update steps, due to the large variety of devices and numerous ways for installing a new firmware, it is recommended that you carefully read and understand the upgrade steps, and consider applying a different firmware only when you have familiarized yourself with the update method.

As the installation process is most of the times quite risky, this step should be taken by users that have the ability to successfully complete the update; regular users may initiate it at their own risk. Moreover, it’s best that this task be performed in a steady power environment such as the one ensured by a UPS unit.

Therefore, if you consider applying this release, hit the download button, take into account all the aforementioned aspects, and update the device’s firmware. Also make sure you constantly check with our website to ensure that you don’t miss a single new release. 

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
