igital storage oscilloscopes HAMEG HMO win many awards because of many reasons, which can be summarized into one sentence – an excellent price / performance ratio. 

Or more in detail – excellent features, user-friendly control and rich equipment with various functions enabling a fast “overview” but even a detailed analysis of measured signals, including math calculations. Inspite of advanced functions Hameg HMO series oscilloscopes maintain a simple intuitive control, thus a user can focus more on the measurement itself, than on a setting of the instrument.

In general, oscilloscopes provide invaluable information and they can´t be replaced by any other measuring instruments. Visual representation of a signal enables to see a real shape of a signal and for example to check, whether we have, in a given place of a device, a signal we expect.

Main properties of of Hameg HMO oscilloscopes we already introduced to you in recent articles and you can also find them in documents HMO Innovations or HMO compact class.
Among features welcomed by perhaps every user belongs a QuickView function which automatically displays the most important parameters (positive and negative peak voltages, rise and fall times, average value) directly in the signal display. Another useful function „Set To Trace“ automatically adjoins the cursors to the respective signals and enables to comfortably measure duty cycle of pulse signals.

6,5“ LCD screen (640×480) is able to display many details. In case, that even this resolution is not sufficient, it is only necessary to use the „Virtual Screen“ function, when the HMO offers a virtual resolution of 1200×640 and 20 divisions in the Y axis. All HMO series instruments feature a metal chassis and housings, that´s why they´re mechanically robust and well protected against disturbances (EMI). Hameg HMO oscilloscopes can be also equipped with options and accessories and they can be upgraded for decoding of UART, SPI, I2C and other buses.

More details can be found in the HMO user manual, comparison of particular types can be found in the HMO overview. Oscilloscopes and other Hameg instruments will be introduced to you in the Hameg Products Overview.

Selected types are on stock, upon request we´re able to provide you with any Hameg DSO (member of Rohde&Schwarz). As an authorized distributor of Rohde&Schwarz we´re also able to provide you with any instrument from the production portfolio of this world-class producer.

Isn´t it the right time to purchase a high-performance oscilloscope? - [Link]

Saelig Company, Inc. announces the SDS5032E – a new, low-cost two-channel oscilloscope which is packed with useful features normally only seen on higher-end DSOs, including external and video-capable triggering, auto-measurements, auto-scaling, a large 8″ high resolution full color LCD display, XY mode, auto-set, averaging, math functions, USB output, waveform storage, pass/fail output, and a 3-year warranty.  FFT functionality is included for frequency spectrum display, in addition to a built-in 6-digit frequency meter, which can measure frequencies from 2Hz to 30MHz.

HAMEG Instruments (a Rohde&Schwarz company) complements the successful HMO Series of DSO/MSO Oscilloscopes by also covering the lower bandwidth range of 70 to 200 MHz.

Recently, we introduced you new user-friendly oscilloscopes HAMEG, reach-featured already in a base version. They offer practically everything, what you can need at a usual work in development or repair, and who wishes to add functionality like I2C decoding or measuring of AC/DC currents, can do this by optional accessories. As we notified their supposed availability to this term, we already have them in stock and they are immediately available.

All types are MSO-ready – it suffices to connect a logic probe (option HO3508) in order to analyze 8 digital channels. With the known option HOO10 two freely selectable serial protocols of the types I2C, SPI and/or UART/RS-232 can be analyzed, hardware-supported and time-synchronous. This is possible both on the analog and the digital channels.

New is the option HOO11 which enable the analysis of these serial protocols on the analog channel. Even with the 2 channel instruments 3-wire buses such as SPI can be analyzed this way by making use of the external trigger input.(additional probe recommended)

The HOO11 will be delivered with each HMO7xx, 10xx, 15xx, 20xx at no cost in the year of introduction.

This cute pocket oscilloscope is a perfect companion to your tool box. For beginners, its a good starter scope – it is not as complicated as a benchtop scope so its easy to use. For advanced EE’s, its useful as a scope-on-the-go, for field-debugging, when you don’t want to drag your scope over, or when a floating-ground is needed (it will naturally do ‘differential’ measurements as long as its not plugged into a computer USB port). It’s not a terribly fast scope, best used for signals up to 100KHz, and it is only a single channel, but we still find uses for it all the time, especially with analog projects!

• Portable and lightweight, only 76 grams and 95mm x 62mm x 13mm
• 320×240 Color TFT display
• Built in Lithium polymer battery, USB rechargeable
• Waveform storage and playback to microSD card slot (microSD card is not included)
• 6 triggering modes
• 1 channel input, 200Khz Analog Bandwidth, 1 Mega-sample-per-second. Best for use on signals from DC to 100 KHz
• Complete measurement markers and signal characteristic
• Built-in Signal Generator
• Comes complete with: 2 types of probes, one with hooks, one for plugging into a PCB, screwdriver, carrying bag, stand
• Updatable firmware!
• DSO Nano manual

DSO Nano v2 – Pocket-size color digital oscilloscope - [Link]

Georg blew out the signal generator on his DSO nano portable oscilloscope. He brought it back to life with a new buffer chip, his repair guide might save your nano too: [via]

Spotting the chip on the board is very easy. It’s in an SMD package but fortunately a rather large type. So, although I have no specific SMD equipment I was able to desolder it. I treated all pins with desoldering wick and afterwards slid the blade of a very thin knive under it while heating the pins.

Dan Reetz found that the 3.5mm jack in his DSO Nano oscilloscope had a broken solder connection so he decided to fix it and document the process. This article shows how to fix it and prevent it from happening again by using glue to reinforce the jack. [via]

After the successful DSO Nano Seeed is finishing development of new pocket scope called DSO Quad. Engineering samples started shipping in late December 2010, now the beta testing run is available for preorders at $159. Be aware that the actual shipping is scheduled for March.

DSO Quad has two analog inputs up to 36 Msps, two digital inputs and one signal generator output. Waveforms and screens can be saved to 2 MB onboard flash accessible over USB. Display resolution is 400×240 px. Firmware will be open source with support for user applications. [via]

In the past, advice on forums has always tended more towards purchasing a second hand scope.  These tend to be had for around £100 on places like E-bay and most certainly will be a few years old if available at this sort of price.  Well that is changing and I was excited yesterday to get my hands on a “Scope” that may just re-write the forum advice.  Meet the Nano DSO from Seed Studio… [via]
