Hp mininote 2133 2tb hdd upgrade6/6/2023 The pages now have the Rohde & Schwarz branding, appearing broadly consistent with the web interfaces of their other products.Ī SCPI device control page is added, with a basic SCPI terminal and the ability to pull a screenshot into the browser. ![]() The process can be completed in about one and a half minutes – illustrated in my video below:Ĭompared to the web interface of the initial release firmware, this one is closer in appearance to what I would expect from an instrument of this class. rsu file from the site and put it onto a USB stick (FAT/FAT32 format), insert it into the instrument and select the Update Device menu option. ![]() This is a most welcome improvement.Īpplying the update is a simple process – download the. Updated webpage – an improved web interface which overcomes some of the criticisms I had of the original web interface.Īlso of note is that the manual has also been updated to correct a number of small typographical errors which I had previously reported, while improving on some of the information about specific features (e.g.Adapted backlight control – should improve LCD lifetime.Fixing digital trigger/output behaviour – which is good since I intend to evaluate this feature in this update post.Fixing energy measurement accuracy – after my initial review went out, I noticed the energy measurement statistics seemed slightly less accurate than I’d expect – this update should improve this.Fixing of a number of file handling issues – this seems to have improved the reliability of USB based data logging, screenshots and FastLog, avoiding a number of strange data save issues I initially experienced. ![]() This makes things a lot more flexible and is a feature I find extremely useful.Of course, existing programs which expect a single context should still operate with no changes necessary, assuming they only use a single SCPI connection. As the supply is able to process a specific channel context, all code that follows from the first program will go only to the first channel, likewise, the second program will only command the second channel without either needing to co-ordinate channel selection commands as a single context would demand. This makes it difficult to use the two channels on the NGM202 for two different tasks without a lot of careful arbitrating of accesses.With this new feature, using the two channels like they were two separate power supplies is as simple as writing two programs – the first would make a connection to the supply and issue INST:SEL 1 to select the first channel, while the second would make a second connection and issue INST:SEL 2 to select the second channel. Trying to use the two channels for separate tasks would require having one program that would manage both channels, sending the appropriate instrument select commands before each sequence of commands. Multiple concurrent SCPI connections with a specific channel context on each connection – this is a great feature which means that the two channel units can be used as if they were two single channel units.In a traditional single context situation, your SCPI program would have to send an INST:SEL command to choose which channel the follow commands would be directed at.This particular update has a number of very interesting and useful features, which makes this update highly worthwhile – such as (but not limited to): The firmware has quite an extensive list of changes – reproduced from the release notes below: Firmware Update V2.005Īlmost right after the publication of the launch-day review, I noticed that Rohde & Schwarz released the first firmware update for the NGM-series, V2.005. Read on to find out what’s changed and to learn more about these functions. I have also had a chance to review the NGM-K103 Digital I/O Option, test FastLog over SCPI and run some interesting FastLog and battery cycle-life experiments. I published my launch-day review of the Rohde & Schwarz NGM202 Two-Quadrant Power Supply on 20th August 2019 and in the one-and-a-half months since then, there has been a new firmware release (and updated documentation) which improves upon some of the issues identified in the review.
