V 2.13 2/13/2008
Note: Starting with firmware version 2.13, 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 +.
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.
Bug Fixes:
- I2C bus decode does not precisely match the I2C specification with
respect to reading data from 10-bit peripheral devices.
+ I2C bus doesnt always trigger correctly when clock and data are
held low during the idle period.
- CAN bus decoding - once an error frame is found, no further decoding
is done.
- Parallel bus thresholds dont work for Bus 4.
- During Play at certain slow time per div settings, the new
acquisition is not displayed.
- Previous XY waveform can be momentarily displayed after leaving
XY mode, when certain settings are changed.
- A double edge can be displayed occasionally at frequencies
below 1kHz.
- "rtl 205x" errors occasionally< |
