Firmware revision updates:- Version 0.171.6 - Fix bug for Tmax and Tmin measuremnt: In Scope T-Max and T-Min measurement for Ch1, Ch2, analyzer channel and also Zoom mode. Version 0.171.5 - Fix display digits resolution in Meter view for DCV and Resistance. - Fix Power Factor and other power measurements issue. - Improve on data start and end with zeros, to get rid of average point causing false zero crossing detection. - Improve on power mesurement on zoom with both end padded with 0 case. - Solve when logged date > 4 hours, Save Data unit hang (exception) issue. Version 0.171.0 - No issue fixed in this version. - Main software rebranding effort from Agilent to Keysight such as bootup splash screen, product web link. Upgrading this version carry no impact to existing customer unit on splash screen. Version 0.170.9 - Modify to restore state after probe cal. - Fix 1/deltaX cursor calculation not cater for Zoom mode, added in factor and condition checking. - Improve frequency cursor placement for zoom mode. - Correction on SINGLE mode time offset Limit check. - Correction on +duty cursor. - Improve on Bounce check for zoom mode when main to zoom ratio is big (e.g.20ms:2ns). Version 0.170.6 - Main mode 1) Resolved the waveform shifting compensation for the <50ns timebase. 2) Removed the Main waveform masking (growing effect) during delay shifting: a) at stop mode in SINGLE. b) at stop mode in High Resolution mode. c) at Normal interleave mode. 3) Restored the previous timebase setting for Main mode when switching from ROLL mode to Main mode. 4) Resolved the issue where Invert on/off in stop mode caused the signal to disappear. 5) Resolved the issue regarding the invalid Invert signal with offset ground reference in Main mode - ZOOM mode 1) Zoom mode waveform masking(growing effect) during delay shifting a) at stop mode in SINGLE. b) at stop mode in High Resolution mode. c) at Normal interleave mode. - Measurement 1) Improved the frequency measurement cursor placement, and accuracy. 2) Improved the measurement module (amplitude, RMS, Frequency, preshoot, and overshoot) 3) Implemented the showing of >/< if the measured waveform is out of screen on an RMS reading. - Others 1) Resolved the Logger OL issue 2) Updated the Raw sampling rate for 1610 50us and the table below it in the user guide. Version 0.160.6 - Fixed hang issue when time/div is set to larger than 50ms - Fixed ZOOM mode issue when time ref is at Left or Right, the zooming waveform is incorrect and signal shown is distorted. Version 0.160.3 includes - Fix on system hang after reboot (from zoom mode) Version 0.150.16 includes - Bug fix on DMM logging spike - Enable 2M Data with corrected waveform polarity - Bug fix ON DMM functional when triggered from Scope'S Zoom mode Version 0.150.9 includes - Fixed USB trace and setup recall - Fixed title language for logger mode - Disable AUTO range for AC+DC - Disable RAW file format Version 0.150.0 fixed few major bugs and added in new software enhancements. - Fixed zoom issue to accurately show the zoomed data with right waveform and position. - Fixed waveform trigger issue in normal mode. - Fixed single shot & DC voltage trigger issue. - Fixed cursors error when measuring negative pulse width/duty-cycle. - Enabled save full 2Mpts raw data in USB drive. - Enabled print screen of DMM and Logger screen in PNG format. - Added QR code in system information. Version 0.140.2 added a few software enhancements:- - Extends standby time from 2 days to 5 months at 50% battery level - Chnange Printer UI - Fixed on Scopelink display issues with U1620A - Optimizing the Progress bar during firmware update - Improved USB detection status Version 0.130.4 added variety of bug fixes and enhancements which include:- - Fixed time reference error - Fixed waveform display issue in zoom window - Improve accuracy of cycle mean and power measurement readings. - Fixed screen lock issue - Save up to 1.2K data point in normal, peak detect and average mode, 12K data point saving in high resolution mode only - Save trace & setup into USB drive - User-define filename for saved trace & setup into USB drive - Transfer screenshot images & logger data from internal memory to USB drive **Compatible with firmware version 126.1 , 128.21 & 129.0** Version 0.129.0 added a few enhancements which include:- - Math scale is included in the saved image. - Added undo autoscale? - Improved zoom window consistency and reliability. - Normal mode triggering is fixed. - Nth edge triggering mode is fixed. - Measurement error fixed on:- Crest factor Cycle mean Active Power Reactive power Apparent power Version 0.128.21 was a software maintenance release which fixed a number of software defects in the product. The fixed included:- - Able to save data logger data to the scope internal memory and transfer the data to a USB drive. - Probe ratio default setting set to 10:1 - The charging symbol will be removed when is the battery is fully charge, even with the power adapter remains connected to the scope. - Math scale is now display upon user selection. - Single mode triggering issue is fixed.
