This firmware supports the DPO2000 and MSO2000 
series oscilloscopes listed above. 

History
-------
V 1.52  08/14/12
Defects Fixed / Enhancements:
- Updated USBTMC interface to improve reliability of USB 
  communications. 
- Updated driver for USB memory stick to recognize memory 
  sticks greater than 2GB.
- Removed 1M point limit for ASCII CURVE? queries.
- Enhanced PI read command ":FILESystem:READFILE"
  to handle large files. 
- Enhanced PI interface to allow for selecting TRIGGERING on a 
  CAN bus bit stuff error (requires the Serial Triggering and 
  Analysis Application Module)
- Enhanced the VXI-11 interface to handle timeouts > 2147   
  seconds.

V 1.39  12/02/2011
Defects Fixed:

- Fixed measurement scaling when measuring current with a voltage 
  probe.
- Fixed measurement updates while in roll-mode.

V 1.35  05/04/2011
Defects Fixed:

- SPI decode errors using SS idle.
- Wide RS-232 bus decode packets handled better.
- Corrected parallel bus decode when there are no digital 
  transitions.
- Fixed System Error when scope Ethernet address is changed from
  DHCP to manual and address re-entered.
- VXI-11 stability improved.
- Added Program Interface compatibility with legacy TDS700 series 
paired cursors.
- Fixed conflict between periodic and immediate measurements.

V 1.31  06/27/2010
Defects Fixed:

- Improved firmware upgrade process. Provides better 
  synchronization of front panel update processes to eliminate
  potential lock-up condition.

V 1.29  05/07/2010
Defects Fixed:

- Enhanced encoder performance for front panel knobs. Improves
  linearity and smoothness of knob operation.

V 1.25  07/24/2009
New Features:
- Channel Invert
  Channel Invert has been added to each channel's vertical menu 
  and to the remote programmer's command interface.
- Video Autoset
  When an NTSC/PAL video signal is input to the oscilloscope, 
  pressing Autoset will set the trigger source for video 
  triggering and an appropriate IRE graticule will be selected to 
  help display the video data.

Bug Fixes:
- Increased cursor accuracy on the FFT waveform.
- Corrected FFT waveform data saved to *.csv files. 
- Improvements in Bus Decoding.

V 1.06  03/12/2009
New Features:
- FFT math feature with the appropriate FFT PI/GPIB commands as 
  documented in the "DPO2000 and MSO2000 Series Programmer 
  Manual." The following are additional DPO/MSO2000-specific FFT 
  PI/GPIB commands that are not currently described in the 
  released Programmer Manual:
  ---------------------------------------------------------------

        :MATH:SPECTral:NYQUISTFreq?
        Description: Returns the Nyquist frequency used for the 
        FFT math waveform. Query-only. 
  ---------------------------------------------------------------

        :MATH:SPECTral:GATing:INDICators?
        :MATH:SPECTral:GATing:INDICators <Boolean>
        Description: Only for those instruments that provide 
        thumbnail waveforms and compute the FFT math waveform 
        based on a portion of the LRL source waveform provide 
        this command. This command enables or disables the 
        display of indicators to indicate the portion of the
        source waveform record which is used to compute the math 
        FFT waveform. 
  ---------------------------------------------------------------
        :MATH:SPECTral:GATing:INDICators:STARt?
        Description: This query-only command returns the starting 
        point in the source waveform  record that is used for 
        computing the FFT math waveform. The value returned is
        the fractional portion of the source record (between 0
        and 1). 
  ---------------------------------------------------------------
        :MATH:SPECTral:GATing:INDICators:END?
        Description: This query-only command returns the ending 
        point in the source waveform record that is used for 
        computing the FFT math 
        waveform. The value returned is the fractional portion of
        the source record (between 0 and 1). 
  ---------------------------------------------------------------

Bug Fixes:
- On four channel oscilloscopes, this release fixed the Save 
  Screen Image to USB Memory behavior. This corrects the mismatch 
  between what is on the screen and what is saved in screen
  image  file.


V 1.03  11/07/2008
New Features:
- None
Bug Fixes:
- Fixed obvious waveform display anomalies when trigger delay 
  exceeds ~500 us.

V 1.02  10/15/2008
Initial Release
