Version: [2.88] Last Revised: [11/07/2012] Products: This firmware supports all MDO4000 Series oscilloscopes. History ------- v2.88 11/07/2012 Defects Fixed: - Support large TIQ files. - Add firmware update notifiers specifically for Signal Path Compensation (SPC) when required. v2.86 10/19/2012 New Features: - New models supported: MDO4014-3 and MDO4034-3. - Improved TIQ file format. Defects Fixed: - Ethernet: fixed DHCP modes and IP Address problems. - Improved operation of power-up RF signal path compensation. - Updated two German translation strings. - Corrected cursor behavior for recall from setup file. - Improved performance of e*Scope PI queries. Other: - Read Install.txt file for notes regarding Signal Path Calibration (SPC) after performing software upgrade. v2.52 4/16/12 Defects Fixed: - Added support for SCPI STATus abbreviation. - Fixed problem with cursor readouts appearing unexpectedly when cursor bars are moved while Menu Off is enabled. - Fixed incorrect display of FFT units that occurred after power cycling the instrument. - Fixed missing histogram in saved screen image when saved using the Save/Recall menu. - Fixed incorrect recall of saved setup when firmware update complete with DPO4LMT module installed. - Fixed time correlation between CH1 and CH2 after a single sequence acquisition that occurred with a large delay and > 1 M record length. - Display of waveform data no longer disappear when switching Delay between On and Off while in roll mode. - Display of channel 1 and channel 3 waveforms no longer disappear after single sequence acquisition and record length is >= 10 M. v2.20 11/21/11 New Features: - Enhanced Menu Off functionality to allow manipulation of cursors while readouts are turned off. - Added programmatic interface command to query noise density and phase noise. Defects Fixed: - Setup & Hold search no longer reports false positives. - Logic search on RF Versus Time traces now works correctly. - The Autoset enable/disable feature now works correctly. - Fixed rare instances when Single Sequence caused incorrect time correlation between analog channels and RF traces. - Notification message "external reference unlocked" added to notify user when the oscilloscope cannot lock to the 10 MHz REF IN external clock input. v2.10 9/2/11 Defects Fixed: - RF Auto Level feature works at all center frequency/span combinations. - Fixed incorrect time correlation between analog/digital/rf under certain conditions when acquisitions have been stopped with the Run/Stop button. - Eliminated "application error" message with R-To-Center button at certain settings. v2.08 8/11/11 Defects Fixed: - RF traces draw more smoothly while panning. - Eliminated excess jitter on channels 2 and 4 under certain conditions. - The amplitude of the RF Amplitude vs Time trace is now correctly calculated. - When RF is turned off, analog acquisition rate is now fully restored. - Search now works on digital channels when MagniVu is on. - Marker readouts now restored after toggling RF state off and on. - The numeric keypad now works correctly with the spectrogram slice number. - Spectrogram color map is now correct after a firmware upgrade. v2.06 7/28/11 v2.04 7/20/11 v2.02 7/13/11 Defects Fixed: - No user-visible changes through version 2.06
