150MHz Digital Storage Oscilloscope, 8K/Channel, USB PC-based US$1,037.00

M526
150MHz Digital Storage Oscilloscope, 8K/Channel, USB PC-based


The M526 Oscilloscope is part the ETC Measuring Lab 3 (EML3) line. The dual-channel USB oscilloscope is compatible with USB 2.0 and USB 1.1 interfaces. You can connected it to a computer using standard USB 2.0 cable, and it will be powered through USB, so no external power supply is needed. This makes the M526 scope extremely portable, given its size of just 106 163 35 mm (excluding connectors and feet). The maximum power consumption of only 2.25W makes it usable with battery-powered notebooks.

The M526 has 150 MHz bandwidth and 8K per channel internal storage. There are six oscilloscopes in the M520 Series, available with 60, 120 or 150 MHz bandwidth and 4K or 8K per channel internal storage. A detailed table of the differences between the six models is found below, so you can compare and choose the one that suits your needs.

All devices of the M520 Oscilloscope Series offer simple and intuitive installation and operation, and they can adapt to any screen resolution from 800 600 upwards. They have two vertical channels with 8-bit resolution and offer a deflection factor from 10mV/div to 5V/div in 1-2-5 steps. The device inputs are accessible via BNC connectors which are compatible with standard probes (with minimum of 32 pF compensation range).

Four standard acquisition modes (AUTO, NORMAL, SINGLE, MANUAL) are available. The trigger event is created by a dual-level triggering system equipped with a digital pulse length filter and event counter on each level. The channel A, channel B and external trigger input can be activated as a triggering system source. The threshold of the channel A and channel B triggers is settable for the whole range of the scope screen. The threshold of the external trigger is fixed to about 1.5V and is TTL and CMOS compatible. This sophisticated triggering system allows displaying waveforms with very complicated trigger events (e.g. selected row of the video signal).

M526 Oscilloscope Features

  • Dual-level triggering system with digital pulse length filter and event counter on each level. This allows displaying of very complicated events.
  • Virtual storage with size of 63000 samples. This feature allows you to delay data acquisition from the trigger event by a maximum of 63000 samples.
  • Simple and complex triggering modes. Simple triggering mode is very easy to use; using the complex mode, you can utilize the triggering possibilities to the fullest extent.
Standard triggering features are also supported, such as data acquisition before trigger, triggering from channel A, channel B and external trigger, or setting the trigger threshold of both channels within the whole vertical range of display.

The vertical deflection system is equipped with all standard features, such as AC/DC switch, GND switch or probe input ratio selector (1:1, 1:10, 1:100). The measuring channel inputs withstand the voltage of 200V with no respect to the selected deflection factor.

A very useful feature of the vertical deflection system is Digital Shielding. When turned on, it removes asynchronous noise from the measured waveform without any influence to the frequency response.

Using the random sampling method is the horizontal deflection system, capable of reaching the equivalent sampling frequency of up to 20GS/s on the M526. It also provides zoom functionality with factors from 10:1 to 1:16. The fastest timebase setting is 200ps/div with zoom factor set to 10:1 or 2ns/div with zoom ratio 1:1. See the tables below for more detailed figures.

M520 Series Oscilloscope Software and Documentation

The standard oscilloscope software, which provides access to all functionality of the device, is available free of charge. The software also configures the scope firmware, so by keeping the software up to date, the scope also is kept up to date. All standard features of modern DSOs (hold acquisition process, hold-off, zoom, etc.) and many more (saving/loading the waveforms for future use, export to clipboard, printing the results together with scope settings) are available. Spectrum analyzer software is the part of basic package. It analyzes the signal on channel A and displays its frequency spectrum.

The included Roll Mode software package will turn the oscilloscope into datalogger with sampling rate from 50S/s to 5Ms/s in USB 2.0, or 50S/s to 250kS/s in USB 1.1. Measurements are written to your hard disk automatically, so the amount of data measured is limited only by your drive's capacity. Measurements are displayed in real time in the Acquisition window; stored data can be viewed with the Roll Mode Viewer application or exported for analysis in third-party applications.

The scope comes with a printed installation guide. A detailed manual is provided on CD. In addition, the software includes tooltip help that can keep you up and running instead of stopping to go back into the manual.

Third-Party Software Support

Use the Model option selector at the bottom of this page to get the Professional version (M526/RM/PRO) which includes an API allowing you to add control functions for the scope in your own software applications. It works in Windows 98SE, Me, 2000, XP and Vista. It comes with descriptions and examples of all libraries written in Inprise Delphi, Inprise C++ Builder, Visual C++ 6.0, Visual Basic 6.0, C# .NET and Visual Basic .NET.
