Firmware update process
The easiest way to update instrument firmware is online:
- Provide the instrument with an Internet connection using Wi-Fi or Ethernet
- Access update screen (System settings > Update)
- The instrument will detect the latest firmware version, follow on-screen prompts to download and install the update
Updating an offline instrument is accomplished with the following steps:
- Click on the desired version number below. This is a link to the .lsfw firmware update file
- Copy or save the .lsfw file onto the root directory of a USB flash drive. Make sure it is the only .lsfw file in that location
- Plug the flash drive into the USB-C port on the back of the instrument, if you don't have a newer flash drive with a USB-C connection, use the adapter that was supplied with the instrument
- Restart the instrument to be given the option to perform a firmware update.
- Disconnect the USB flash drive once the update is complete
M81-SSM Firmware Changelog
1.5.2022032315 — 22-3-25
Changed
- Manual description of filter optimizations and how certain selections affect available measurement ranges; range and filter optimization info circles now explain that available ranges can change based on filter optimization settings
- Instrument now informs the user of unexpected errors that require restarting the instrument before resuming use
- Manual description explains read query versus fetch query operation regarding existing versus newly obtained measurements
- Data streaming mode rate consistency significantly improved for longer duration measurement runs and UI remains active during acquisition
Fixed
- Enabled functionality of "reset settings," "unload," and "load" buttons when front panel keypad access is locked
- Self-calibration of CM-10 when using 50 Hz power line regions provides sufficient range settling times, reducing chances of errors
1.4.2022021701 — 22-3-2
Changed
- CM module self-calibration function unavailable while module high reserve filter function is enabled
Fixed
- External reference input now detects when input signal has been stopped or cable is removed
- Improved stability when long term, high reading rate remote PC queries are being conducted
1.3.2022012604 — 22-1-28
Added
- Added front panel load/unload function to allow remote modules to be connected and disconnected without cycling instrument main power for quick module setup reconfiguration; prior to power on module disconnect, select unload at bottom of module interface screen; upon module connection, follow on-screen prompts to load module to activate/use each module connected while power is applied
- Added module reset at bottom of module interface screen to restore all module settings to default settings, thus avoiding module disconnect/reconnect process to reset a single module; other connected modules are not affected, only the module linked
to the interface screen being reset
Changed
- Source module frequency setting is read-only when module has sync mode enabled
- Improved startup error message when line frequency detection fails on power-up due to noisy power line conditions
- Default state of BCS disable output on compliance feature is now off by default; for voltage-sensitive devices, recommended to set BCS to standby before connecting or disconnecting from DUT
Fixed
- A bug where "disabled due to compliance" message was being erroneously displayed on the BCS module screen
- A bug where in certain conditions the monitor output scaling is incorrect
- A bug where VM peak readings would indicate zero when autoranging and near range boundaries
- A bug where measurement modules' lock-in frequency reading was incorrect when the reference source for a given module was set to 'Ref in'
1.2.2021121002 — 21-12-20
Added
- Calibration page has calibration information for all modules and a button to run all self-calibrations
- M81-2 and M81-4 now filter out irrelevant channels
- BCS module will disable its output upon a compliance condition by default (user defeatable)
- FIR PSD filter cycles can now be configured on applicable modules
- Frequency range threshold can now be configured on applicable measure modules
- 'IMMediate' queries were added to the 'FETCh' subsystem to allow for returning data without waiting for settling
- Source amplitude now has the ability to be viewed and entered in either RMS or peak values
- Bias voltage amplitude control dashboard panel for CM-10
Changed
- The trace subsystem and the questionable condition register (DSOV bit) now report instrument to host PC data streaming overflows; internal data streaming overflows are still reported as runtime errors
- When high-speed data streaming, the instrument will show a lockout screen to help prevent data streaming overflows
- Auto-range logic now uses peak indication instead of raw peak ADC codes
- When source coupling is set to automatic and the output frequency is 100 Hz or lower, the instrument will use DC coupling
- Current compliance now has a minimum value of 1 nA
- Various UI interaction improvements including increased touch detection areas for small/corner buttons
- Auto source coupling now selects DC coupling when the source shape is set to square
- SCPI controls for Disable on Compliance setting
Fixed
- Dashboard scrolling issue
- Issue where crash logs were not automatically being saved
- 'TRACe:FORMat:HEADer?' source limit units
- The trace subsystem and the questionable condition register (DSOV bit) now report instrument to host PC data streaming overflows; internal data streaming overflows are still reported as runtime errors
- Issue where an instrument to host PC data streaming overflow would also cause an internal overflow
- Issue where the measure frequency dashboard panel showed a mode conflict when in lock-in mode
- issue where some settings were not being displayed properly on startup
- Issue where the 'READ' subsystem SCPI errors were all generic system errors
- Issue where calibration temperature does not show on the UI in some instances
- Fixed issue where the instrument could hang when setting an invalid square wave frequency
- Fixed issue where range based frequency validation was falsely generating errors in DC mode
1.1.2021080613 — 1-08-18
Added
- Dashboard view
- Settings profiles
- Option to disable module LEDs (dark mode)
- READ? query
- Built-in calculation of settle time and equivalent noise bandwidth (ENBW)
Changed
- CM-10 autorange now makes range decisions based on both frequency and amplitude
Fixed
- Various bug fixes
