A very brief look at the new WENS 540 Debug Meter with Charles from Trio Test at the Electronex show stand:
This is NOT a review, or my normal blog content, it’s just a quick look because some people may be interested in it. So please, no silly complaints.
A combination 10MHz oscilloscope, 50000 count meter, 8 channel logic analyser, data logger, serial protocol analyser, and digital pattern generator.

Visual Analyser is a complete professional real time software, transform your PC in a complete set of measurement instruments; no new hardware necessary (you can use the Sound Card of your PC) or you can use a specific external hardware (see Hardware section for an example). Visual Analyser runs on Windows 9x,ME,2k,XP,NT,Server,Vista,7. VA 2011 version now available, no longer compatible with Windows 9x. The 2011 version runs on Linux by means of wine utility.
- Oscilloscope (dual channel, xy, time division, trigger);
- Spectrum Analyzer with amplitude and phase display (linear, log, lines, bar, octaves band analysis 1/3, 1/6, 1/9, 1/12, 1/24);
- Wave-form generator with “custom functions”, triangular, square, sinus, white noise and pulse generation (NO ALIASING);
- Frequency meter (in time and frequency domain) and counter; in time domain by means of a real time zero crossing algorithm;
- Volt meter with DC, true RMS, peak to peak and mean display;
- Filtering (low pass, hi pass, band pass, band reject, notch, “diode”, DC removal);
- Memo windows (data log) for analysis and storage of time series, spectrum and phase with “triggering” events; possibility to save in various formats and display them with a viewer;
- A TRUE software digital analog conversion (for complete signal reconstruction using Nyquist theorem) ;
- Frequency compensation: one can create/edit a custom frequency response and add it to the spectrum analyzer spectrum ; added standard weighting curves A,B,C in parallel with custom frequency response;
- Support for 8/16/24 bit soundcard by means of API calls;
- Unlimited frequency sampling (depend from the capabilities of your soundcard);
- Cepstrum analysis;
- Cross Correlation;
- Extended THD measurements, with automatic sweep and compensation.
- ZRLC-meter with Vector scope, automatic sweep in time and frequency for automatic measurement.

It doesn’t matter how you connect the test clips to the component, the Atlas DCA can analyse a vast number of different component types including bipolar transistors, enhancement mode MOSFETs, depletion mode MOSFETs, Junction FETs (only gate pin identified), low power thyristors and triacs (less than 5mA trigger and hold), diodes, multiple diode networks, LEDs, bi-colour and tri-colour LEDs. It will even identify special component features such as diode protection and shunt resistors in transistors.

This page describes a very low cost logic analyser using an 18F2525 PIC microprocessor and a PC. The PIC is used as a hardware capture device which monitors the datalines and records all changes. The buffering, triggering, interpretation and display is handled by a PC program running under Windows. The hardware cost will vary between €15 (RS232 version) and € 30 (USB version). The analyser can operate in a “Fast Sampling” mode, in which the data is sampled into an internal 1K buffer on the PIC and in “Normal Sampling” or “Continious Sampling ” mode in which all data changes are offloaded to the PC in real time and arbritary sampling buffer size is available.

There many wireless devices available on the market now that broadcast in the 2.4GHz spectrum including Bluetooth, 802.11a/b ethernet (WiFi), Zigbee, wireless USB, cordless phones, wireless mice and keyboards and the humble microwave oven. Depending where you live in the world your government has allocated a roughly 80MHz block for transmitting all manner of data starting at 2.4GHz. It’s getting a bit crowded in this band, especially if you live in a built up urban area. With this project you can monitor what’s going on and figure out what channel to change your WiFi network to in order for it to keep working when your neighbor rudely sets up their wireless network on the same channel as you (that’d be channel 6, you lazy sod).
