History
-------
v3.18 11/20/2014
New Features:
- Support for DPO4BND module

Defects Fixed:
- Fixed RF manual marker value readout when overlapped
- Fixed color scheme for XY cursor readout
- Fixed gated waveform measurements for RF vs. time waveforms
- Fixed an instrument crash in certain cases with RS232 packet decode
- Fixed readout for application module license transfer when module
license was already transferred to another scope
- Fixed printer list refresh when saving screen or network printing
with Ink Saver On
- Fixed Acquisition self-test failures when scope record length was
previously set larger than 10k
- Fixed E*Scope issue with RF Normal spreadsheet transfer

Known Issues:
- RF vs. Time waveform measurements using screen gating may return
"Measrmnt Sys Err" when changing horizontal scale. To workaround
the issue, change horizontal scale again or set measurement
gating to Off (Full Record)

v3.14 7/15/2014
New Features:
- New user interface look
- FastAcq(TM) high-speed waveform capture rate and color- and
intesity-graded display
- Act-on-Event added in the Test menu
- Edge trigger now available on rising, falling or either edge
- Search mark table
- Support for e-print
- Display auto dim
- Math autoscale on/off control added to Math menu
- Network mounting of Mac hard drives on OS/X 10.7 and later
- Video picture mode (requires DPO4VID application module)
- Digital channel activity monitor on MSO models

Defects Fixed:
- Fixed CSV channel label issue
- Fixed probe menu usage when probe installed in AUX IN
- Fixed TCP0020 bandwidth issue
- Fixed Curve Query on digital data when 100k record length used
- Improved trigger level setting when RF power trigger used and
PreAmp attached
- Improved RF SPC

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:

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:

persist thru power cycle
- 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.

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.

a single sequence acquisition that occurred with a
large delay and > 1 M record length.
