Version: [2.68] Last Revised: [04/25/2012] Products: DPO4032/DPO4034/DPO4054/DPO4104 MSO4032/MSO4034/MSO4054/MSO4104 This firmware supports the DPO4000 and MSO4000 Series oscilloscopes. Note: Starting with firmware version 2.15, there are some features and bug fixes that do not apply to DPO models with a serial number of C020000 or less. Those items are denoted with a '+'. (DPO4000 Series products with serial numbers = 1M record length. v2.62 10/20/2011 New Features: - Enhanced Menu Off functionality to allow manipulation of cursors with readouts turned off. - Improved y-axis cross hair alignment with waveform when cursors are on. Defects fixed: - Correction to harmonics graph in Power Application. v2.58 5/25/2011 Defects fixed: - Restored backward compatibility for Programmatic Interface commands LESSthan and LESSThan MOREthan and MOREThan :TRIG:B:UPP:CH v2.56 5/06/2011 Defects fixed: - Some non-volatile memory settings, including number of power-ups and operating time, were not correctly restored after a firmware update with v2.54. After a v2.54 update, these settings will not represent accurate data and cannot be restored. With v2.56, non-volatile settings are correctly restored if the user has not already upgraded to v2.54. If a unit was updated to v2.54, this version is unable to restore the original settings. v2.54 4/14/2011 New Features: + Serial trigger and bus decode for MIL-STD-1553 standard. (Requires DPO4AERO application module.) Includes the following: - triggering, decode and search. - Application Modules have licenses that can be transferred between an Application Module and an oscilloscope. - Permits the use of more than 4 applications simultaneously. - Enables usage of an application on the oscilloscope while the physical application module can be removed and stored in a secure location. - Limit and Mask testing Application (Requires the DPO4LMT application module) Includes the following: Limit Testing, Telecommunication and computer Standard Masks, Custom Masks. - SPI Trigger increased to 50 Mb/s - Timeout Trigger - DPO OFF (zero persistence) - Solid Line Graticule - Socket Server Support. - Recall of waveforms in CSV file format. Defect Fixed: - Correct various RS-232 and I2C problems in Event Table. - Fix excessive digital channel jitter in Zoom mode. v2.48 12/01/2009 New features: + Serial trigger and bus decode for USB2.0 serial standard. (Requires DPO4USB application module.) Includes the following: - Low-speed triggering, decode and search; - Full-speed triggering, decode and search; - High-speed decode and search. - Waveform Histograms. Includes the following: - Vertical and horizontal histograms; - Measurements on waveform histogram data. - New Cursor Model with the following: - New Cursor Menu (press and hold Cursor front panel button); - Cursor functions all conveniently contained in Cursor menu. Performance Improvements: - Some programmatic interface commands have been added for backward compatibility with older instrument control software. Defects Fixed: - Problem using the P5205 probe with the TPA-BNC adapter. - Video Out timing does not conform to the VESA Monitor Timing standard (Version 1.0, Rev 0.8). v2.30 6/10/2009 Defects Fixed: - Digital waveform display is now correct with slow triggers. - Input impedance is now set correctly with a TPA-BNC Adapter. v2.28 2/9/2009 New Features: - Support for the DPO4PWR Power Analysis application module. Includes the following measurements: - Power Quality - Switching Loss - Harmonics - Ripple - Modulation - SOA (Safe Operating Area) + Serial trigger and bus decode for the I2S Audio standard (Requires DPO4AUDIO application module.) Includes the following formats: - I2S - Left-justified - Right-justified - TDM - PictBridge printer support - Trigger frequency readout - Save All Waveforms to File - Animated Progress Indicators. Performance Improvements: - Improved cursor readout resolution - Analog channel acquisition rate is improved when digital channels are turned on. - The Probe Setup menu has been improved to provide enhanced control of current probes to support power measurements. - Some programmatic interface commands have been added for backward compatibility with older instrument control software. v2.15 4/4/2008 New Features: + Serial trigger and bus decode for LIN standard. (Requires DPO4AUTO or DPO4AUTOMAX application module.) + Serial trigger and bus decode for FlexRay standard. (Requires DPO4AUTOMAX application module.) - SPI Bus word size can now be specified from 4 to 32 bits. Previously it was hardcoded to 8 bits. - SPI bit order can now be specified as most significant or least significant first. + SPI bus now supports 2-wire decode and trigger by allowing idle time framing to be specified. - CAN bus now triggers on Bit Stuffing Error. - CAN bus now supports custom bit rates. - RS232 bus now supports 9-bit data. - RS232 bus now supports custom bit rates. - Delay On/Off control added to Acquire menu. - HiRes acquisition mode now available with Roll Mode. - Save Waveform Gating - save only a portion of a waveform. - Screen annotation was added to the Utility->Display menu. Previously this functionality was only available over the programmatic interface via the MESSAGE commands. - Automatic timing measurements now work on digital channels. - Four new "counting" measurements: positive/negative pulse count and rising/falling edge count. Performance Improvements: - I2C missing ACK now displayed only for actual errors. + CAN bus sample point range increased to 5-95% (was 25-75%). - CAN bus waveform now shows packet errors. - RS232 bus data values can now be entered in ASCII format. - Reset Horizontal Position button in Acquire menu is now a bottom- bezel action button rather than invoking a side menu. - Various improvements to Autoset behavior in corner cases such as when there are no input signals. - Some side menus now use knob-controlled lists that cover up less of the graticule area. - The measurement menu now shows graphical and textual "help" descriptions of the various measurements. - All menus that have adjustable thresholds now have a list of presets for easier setting to commonly-used values. - The Logic Trigger and Setup & Hold Trigger menus have been greatly simplified. - The Add Printer menu now remembers previously entered information, making it much easier to add multiple similarly-named printers. - Various cosmetic improvements in the user interface. - Improvements to Trigger Level Accuracy test during calibration. - Improved instructions in factory calibration menus. - Reference waveform Ref Details menu now shows the sample rate and record length of the reference waveform. - Waveform intensity and persistence algorithms have been significantly improved.
