Solved Issues:

• IQA Mode: Fix the issue of averaging invalidation.
• MA Mode: Add the import/export function for constellation diagram editing configurations；Add some commands for setting APSK32
• NF Mode: Modify the minimum value of the frequency multiplication numerator/denominator to 1.
• PU Mode: Not support negative pulses analysising, and convert them to positive pulses.
• RTSA Mode: Add multiple marker display.
• PN Mode: Fix the issue of Correction save failure after editing.
• EMI Mode: Reset both RBW/Step to 1 when switching CISPR frequency bands, to avoid excessive data points.
• SYS: Add option descriptions.

New Functionality:
 Add user calibration for reference clock Improvements：
 SA mode: optimize refresh efficiency
 AMA mode: optimize AF smoothing effect
 NF mode: exporting table results as .csv files
 Add FTP switch function Solved Issues:
 SA mode: align estimated scan time and regular scan time
 BT mode: solve issues including Preset, EDR signal demodulation, and no response to quick operations
 PN mode: solve issues including signal averaging failure and incorrect sweep width
 NF mode: solve issues including calculation errors
 RTSA mode: solve issues including no waveform in screenshots, peak failure,failure to save and load files, and missing reference offset
 Add and modify SCPI commands:
1. Period cursor reading error (:CALCulate:MARKer:FCOunt:X?)
2. Query cursor function returns off (CALCulate:MARKer:FUNCtion?)
3. Setting external trigger command is inconsistent with programming manual(:TRIGger[:SEQuence]:SOURce)
4. Harmonic analysis command is missing to obtain each order harmonic frequency and power and obtain total harmonic distortion(:READ:HARMonics:AMPLitude:ALL? :READ:HARMonics:DISTortion?)
5. SA command reads back cent, low, high.Q results when obtaining NDB results(:CALCulate:MARKer:BANDwidth:RESult?)

New Functionality:
 Add Phase Noise Measurement Mode
 Add Noise Figure Measurement Mode
 Add Pulse Measurement Mode
 Add Blue Tooth Analysis Mode
 Add AF spectrogram, SNR,Dist/Total,THD parameter analysis results in AMA
Mode
 Add image browsing in SYSTEM
Solved Issues:
 EMI mode Scan Only rescan with one less count issue
 EMI mode sending command unable to rescan meter and Meas issues

Improvements:
 Support EMI mode
 VNC interface optimization
Solved Issues:
 The default detection type of the third-order intermodulation in SA mode is changed to Pos
 Fixed cursor readout update error when the readout type is not auto
 10db higher signal amplitude under harmonic analysis
 Harmonic analysis cannot modify the number of harmonics
 MA mode time domain graph marker display unit corrected to dBV
 Solved the problem that FTP cannot be used
