1.Solve the problem of output desynchronization when modulation depth/phase deviation/frequency deviation is changed in channel tracking mode with AM/PM/FM modulation
2.Solve the problem of abnormal output waveform when switching back to the internal clock when the external reference clock is abnormal.
3.Solve the problem of occasional abnormal output waveform after power on
4.Add the function of long pressing store/recall to save screenshots

1. Compatible with Rev.F hardware
2. Support trig dual channel separated when use mannul trigger.
3. Support using another channel as the modulation source
4. Support setting the output frequency after the completion of sweep
5. Counter add fast measurement mode
6. Change the square waveform data used in square FM modulation

1. Changed the amplitude strategy of AM modulation: The carrier stays fixed at the amplitude, regardless of the modulation setting.
2. Increased the upper limit of Harmonics number from 10 to 16.
3. Supported Multi-Device Synchronization.
4. Supported Up followed by Down Sweep mode in Linear sweep (no change for Log sweep).
5. Added an icon to indicate clock source is internal or external. Internal: External: External and the clock is lost:
6. Changed the clock switch strategy: When the clock source is set to External and no actual external clock signal is being received, the clock source will not switch to Internal automatically but the clock icon will indicate that external clock is lost
7. Supported specifying Arb type by remote control when the modulating waveform is Arb.
8. Optimized the UI of selecting built-in arbs
9. Supported changing the unit of amplitude without any amplitude change by long pressing the "Amplitude" softkey.
10. Added "User" option under "PowerOn Setting".
11. Added "Normal" as a new UI color style.
12. Added memory space information in Store/Recall UI.
13. Optimized response of the universal knob
14. Added indicator for double function of the soft keys =>
15. Removed the warning message when parameter is set to a value beyond the limit
16. Fixed several bugs
a) [2017/04/07-92573] Digit changes when setting delay of Pulse by the knob
b) Amplitude unit “dBm” is not remembered after a reboot
