Version: [1.44.3.433]
Last Revised: [22-Aug-2022]
Products: This firmware supports 4, 5 and 6 Series MSO products
This firmware version is intended for:
MSO44, MSO46, MSO54, MSO54B, MSO56, MSO56B, MSO58, MSO58B, MSO58LP,
LPD64, MSO64, MSO64B, MSO66B and MSO68B
New Features:
- Enhanced waveview mask hits feature with consecutive waveform hits.
When the Consecutive Failures setting is greater than 1, then the scope tracks
consecutive waveform mask hits and reports pass/fail.
- Multi Source Cursor Readouts are shown in waveview or on Cursor badge.
Configure Cursor Type as Waveform and Cursor Source as “All”.
This will display signal voltage and delta cursor values of all
active sources
- Display Vertical Offset in the waveview channel handles. Configure Channel Offset
from the Channel Vertical settings page. This will display the offset (if any)
directly in the waveview without opening the Channel context panel
- Display Spectrogram for the active channel Spectrum View
- Show Measurement annotations on Spectrum View measurements
- Wide Band Gap – Double Pulse Test (WBG-DPT)
- New measurements added:
- Switching d/dt for voltage and current source
- Diode d/dt
- Irr – Reverse Recovery Current statistics
- Overlayed plot added in Reverse Recovery Time (Trr) measurement.
User can view Trr results in single or overlay mode based on the selected
pulse region
- Search direction feature extended to Backward in addition to
Forward direction
- WBG-DPT specific Deskew added to adjust the skew between double pulse
switching signals. WBG Deskew calculates the skew between Drain to Source
Voltage (Vds) and Drain Current (Id) or Collector to Emitter Voltage (Vce)
and Collector Current (Ic) when Power Device is MOSFET or IGBT respectively.
The skew value is then applied on to the source to which Vds or Vce signal
is configured on the scope.
- IMDA updates:
- Acq trend plot added for Mechanical Power and System Efficiency measurements
- Measure Speed, Angle, Mechanical Power, and System Efficiency using Resolver sensor
- 5/6-PWR updates
- Enable History mode on Power measurements except Single sequence and FRA measurements
- Power, IMDA and DPM demo files using ref waveform
- New column is added in FRA results table to show input and output linear
voltage values
- Spectrogram is a visual representation of signal strength over time at various frequencies.
It is a two dimensional graph with third dimension indicating signal strength
- Cursor A/B support helps to compare spectrums in up to three different locations
on a single source in a single view
- Zoom support enables Spectrogram to be drawn for given zoom window in waveview
- Color Scale helps to set the colors for Minimum and maximum dB units
- New RF Measurements
- Channel Power measures the total RF power within the bandwidth defined
by the channel width
- ACPR measures the signal power leaking from the main channel into
adjacent channels upto 5 channels
- OBW measures the occupied bandwidth
Defects Fixed:
- When signal amplitude is low then Cycle RMS measurement shows zero population
with no error message
- Plugging TPP1000 on CH2 of 6B Series MSO breaks CH1 termination
- Trigger Setup & Hold image is incorrect
- Cursor delta value unit on Rf vs Time magnitude trace shows in dBm instead of dB
- Integration operation at higher record length on math waveform returns
incorrect result
- At slow horizontal sweep speed (like 10sec/div), the gated measurements display
"No data in range" message even when the waveform exists within the gated region
- No programmable interface command exists to query the success/failure of
probe AutoZero
- AutoZero status cannot be queried through *ESR? and :ALLEV?
- After changing the spectrum view vertical scale, Save and recall session file
does not recall spectrum view vertical scale
- 5 Series MSO shuts down from invalid temperature reading
- On 4 Series MSO, Setup a search, then zoom on one event and try to navigate to
the next event using navigate button, after some movement the zoom window starts
to move on its own
- On 4 Series MSO with Linux OS, Files saved are timestamped with the GMT time
instead of the set time zone
- User manual does not show the complete list of help topics in the Contents tab
- Value returned by :wfmoutpre:pt_order? is incorrect when FastAcq PIXMAP mode is enabled
- Trigger B Event is being reflected as Trigger A Event
- FastFrame and saving images/data have sync errors. Sometimes the measurement
results displayed in the badges for the selected fast frame may not match in the
saved screen capture
- Scrolling through Bus decode or Math make the screen flicker
- When using the control loop response with amplitude profile mode,
plot generated is not smooth
- Vertical scale displayed as dB_/div instead of dB/div when spectrum view is on
- Branch queries does not always return results in a fixed order
- MAV bit is not cleared after scope output is read
Known Issues:
- Cannot change the time zone from PST to JST through PI command
- When network directory is successfully mounted, and when the network connection
is lost, the drive later becomes a phantom drive and cannot be unmounted
- AFG settings cannot be recalled from setup or session files
- On 6 Series MSO with FastAcq on, inserting a 4 GHz TDP7704 hangs the scope
- Autoset restricts the channel vertical scale to 1mW/Div
- SPI BUS trigger does not trigger on the defined Data
- TDP77 probes should not be supported on 4 or 5 Series MSO
- RS232 bus decode can not search for multiple bytes
- External monitor causes touchscreen to not work properly
- Linux Scopes have issues with unmounting completely blank drives.
The similar issue is seen with the network drives as well.
The workaround is to add some files before unmounting the drives.
Sometimes the network drive unmount is seen when network connection is lost
- \n newline character in FILES:MKD PI command crashes scope.
Workaround is to use the escape character “\” before the “\n”
- NFS mounts cannot be programmatically set as CWD on 4-Series MSO
- Save Screen Capture with opposite colors of display colors fails.
The workaround is to go with Displayed color settings (either normal/inverted)
rather than the Screen Capture colors while saving the screen captures
- Spectrum View is turning off when I turn off the Ch1 display. This issue
happens only when the channel display is turned off from the short-cut right
click menu. The workaround is to use the context panel display on/off toggle switch.
- Horizontal scroll bar not available for tab based results table similar to
measurement results table. Since the scroll bar is not shown, the user has to
use the touchscreen swipe gestures to scroll horizontally in tables.
- With History mode On and higher record length (i.e. >1M), some of the computation
intensive power measurements like magnetic property, harmonics and switching loss
are expected to run slowly
- Reference signals with modified skew value are not supported in WBG-DPT
