Fixed a calibration bug only existing on Rev.G hardware (06-xx)

1. Measurement enhancement – Added setup/hold time: tsu@R, tsu@F,
th@R, th@F
2. Optimized UI
3. Added SCPI commands for Measure Cursors and clearing measure
items in Simple mode
4. Supported LXI (only with the Uboot-OS Version 5.4)
5. Supported time zone setting
6. Fixed several bugs
a) Webserver doesn’t show instrument UI if the scope reboot with a
wireless mouse connected
b) Incorrect “Recall”icon in the File Manager
c) Scope freezes with AWG enabled and measure cursor on rise
time
d) IP setting of AWG in Bode Plot not remembered after reboot
e) Network storage only works for SMB1.0
f) MEAS:SIMPle:ITEMsOVSN,ON does not work as expected
g) Roll time incorrect at 1ks/div and 20kpts
h) Raw data not consistent in x and sinx/x interpolation modes
i) Math: Dx parameter of Derivation cannot be increased by
universal control
j) Incorrect FFT sample rate

1. Fixed several bugs of 1.3.9R10
a) Compatibility issue on 2-channel models
b) WebServer control issue

Compatible with new hardware (hardware version: 04-xx).
Note:

1. This is a firmware compatible with new hardware. No feature or specification difference between it and 1.3.9R6. It’s not necessary to upgrade it from 1.3.9R6 to this release.
2. This release cannot be downgraded to former releases.

Fixed several bugs
a) When selecting the option screen the scope hangs
b) Wrong FFT frequency when memory depth > 10 Mpts
c) Incorrect network storage path leads the scope to hang

1. 1. Measurement enhancement:
   1. a) Supported cursors for measurement
   2. b) Supported Track plot
   3. c) Added parameters: Positive Slope and Negative Slope
2. 2. Display:
   1. a) Supported to display axis label
   2. b) Auto hide menu setting increased to 10 seconds
      c) Added “Hide” button in the fast menu of channel for quickly hiding
      trace
3. 3. Save/Recall:
   1. a) Supported network storage
   2. b) Supported to Print only grid area
   3. c) Supported to save FFT result
   4. d) Updated the File Manager
4. 4. Bode Plot:
   1. a) The maximum generator amplitude changed from 6Vp-p to
      24Vp-p
   2. b) Supported single sweep
5. 5. Horizontal: Time Zero strategy updated – time zero changed from
   center display to trigger position.
6. 6. Acquisition: Deleted some unnecessary clear operations on the history
   buffer
7. 7. Updated Russian menu
8. 8. Supported setting Cursors by virtual keypad
9. 9. Fixed several bugs
   a) Decode failure occurs on last nibble or byte
   b) The “STL?” query issue in AWG function
   c) If persistence is enabled, and you change the trigger setting,
   persistence will be switched off
   d) Decode list can’t go higher than item #2
   e) Decode format is reset to “binary” when recalling stored settings
   f) Sequence capture does not work with serial trigger from digital
   channel
   g) ERES 0.5-bit works for ERES(C1), but not for ERES(F1)
   h) The icons for rise and fall time in the Measure Select screen are
   reversed
   i) When switching the attenuator, the message “Zone is too small”
   appears
   j) After shutting-down the scope and rebooting not all settings are
   restored
   k) Bode plot abnormal when Sequence is enabled
   l) SENT decode: tolerance not functional
   m) SENT decode: only display CRC segment but no calculation on
   the CRC checksum
   n) SENT decode: The Short Serial data is NOT decoded if only 16
   frames are sent. If a 17th frame follows, the data is decoded
   o) SENT decode: Changing the horizontal time/div affects the ability
   to decode.
   p) Save/recall: Number of digits of time stamp is not enough in the
   long period
   q) Infinite persistence not works after switching between 8-bit and
   10-bit
   r) Tolerance of UART decode too strict
   s) FFT max. scale is unrealistic

1. New serial protocols supported (optional):
a) SENT, trigger & decode
b) Manchester, decode only
2. Measurement enhancement:
a) Supported user-defined thresholds (Upper, Middle and Lower):
Measure | Config | Threshold
b) Added items: +Area@AC, -Area@AC, Area@AC, AbsArea@AC
3. Math: added new operator – Interpolate
4. Display:
a) Supported selectable color for traces: Display | Color Setting
b) Supported floating menu so that the waveform is not compressed
horizontally when the right-side menu is displayed: Display | Menu
Style
c) Supported to show bandwidth information on the channel
descriptor box
5. Save/Recall:
a) Added option “Save all channel” for csv file
b) Supported to save math traces (except FFT)
6. Bode Plot:
a) Optimized scan speed
b) Fixed unexpected glitch issue
7. Supported serial trigger as source of the frequency counter
8. Unlocked zoom in stop mode for Roll
9. Supported trigger Default or AutoSetup operations by pressing
corresponding button twice

10. Fixed several bugs
a) Some vertical measurement error in roll mode
b) Missed peak marker in FFT two-tone test
c) AWG problem of importing the arb file from a U-disk
d) Whenever the screen is touched, the pass/fail statistics is reset to
zero
e) SPI data value setting issue using virtual keypad
11. Compatibility issue between WebServer and latest Chrome/Edge
browsers
