History
-------

v3.06  12/10/2013

    New Features:

    - RBW range extended up to 200MHz
    - Spectrum trace reset
    - Spectrogram timestamps (rolling and slice)
    - RF power level trigger bandwidth readout
    - RF vertical position range extension to +-100 divs
    - Frequency vs. Time trace defaults to Span/10
    - Phase vs. Time controls (reference point and wrap)
    - RF vs. Time traces have unique colors
    - RF vs. Time readouts indicating baseband bandwidth
    - RF vs. Time readouts indicating negative frequency (Start Freq. < DC)
    - Saving I&Q data to MATLAB

    Defects Fixed:

    - Fixed missing channel labels and vertical settings for channels
      2 and 4 in saved CSV file.
    - Corrected vertical power value displayed in RF Probe Setup menu for
      TAP2500 and TDP1000 probes.
    - Fixed loss of channel data after channel is switched off then on 
      again while acquisitions are in stop mode.
    - Fixed Socket Server Protocol None response to a query.  The defect
      was that in raw socket mode, a second query was needed to clear out
      the instrument buffer which had new line and carriage return (LFCR).
      The defect was resolved by terminating all responses in raw socket
      mode with only the new line (LF).

    Defects Fixed:
    
    - Ethernet: fixed DHCP and IP Address settings such that they 
      persist thru power cycle
    - Improved operation of power-up RF signal path compensation.

    - 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.

      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.
