1. Optimized TrueArb algorithm and added 3 types of
interpolation: sinc, sinc27 and sinc13
2. Optimized jitter performance of Square and Pulse
3. Optimized algorithm of Noise generating so the bandwidth
setting lower limit of Noise optimized from 80 MHz to 1
mHz
4. [2017/12/22-174663] 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
5. [2017/12/22-174663] Changed default state of 10 MHz
Out to “Disable”
6. Added Slave Delay option in Multi-Device Synchronization
function
7. Added indicator for double function of the soft keys
=>
8. Fixed the following bugs:
a) Crashes when downloading 20 Mpts waveform data
from the EasyWave program
b) Inaccurate burst delay
c) In TrueArb mode enabling AM with large amplitude
may trigger OVP
d) Switching the waveform from IQ to sine with large
amplitude may trigger OVP
e) Switching off the output on the SDG6kX only drops
the output level by approx 20 dB but does not
completely switch it off

1. Removed the warning message when parameter is set to
a value beyond the limit
2. Supported to copy/paste/delete folder in Store/Recall file
manager
3. Optimized initialization time when the waveform is
switched between IQ and other waveforms
4. Supported phase compensation in IQ mode
5. Fixed several bugs:
a) [2018/09/14-924144, 2018/09/14-937446] Signals
get interrupted upon timing-related change of the
settings in Independent mode
b) Anomaly on square/pulse waveform with some
setting
c) [2018/11/06-92208] Anomaly on arb waveform when
toggle the “ArbMode” from DDS to TrueArb and
back to DDS in Independent mode

1. Changed the upper limit of carrier frequency (sine) in
Burst mode from 300 MHz to 500 MHz
2. Added some missing SCPI commands
3. Fixed several bugs:
a) Messed up signal after switching from 500 MHz sine
to square in independent mode
b) Glitches when outputting pulses under certain
circumstances in independent mode

1. Allowed one channel to modulate the other
2. Supported Burst in TrueArb mode
3. Supported Burst Counter in Burst mode so the number of
burst trains can be set to > 1 when trigger source =
external or manual
4. Added an option to let the SDG start with activated
outputs
5. Added 50 ohm output impedance text in the UI
6. Able to remember the digit of a parameter that had been
modified
7. Fixed several bugs:
a) DDS interpolation bug
b) Switching on/off output causes random phase
deviation between channels in Track mode
c) Incorrect square/pulse waveform initialization in
some cases
d) Unable to store the level settings for noise
e) Unable to recognize the command MODE
PHASE-LOCKED
f) Freezing issue when being written a 20MB long file
with the EasyWaveX
g) The setting “BANDSET” with Waveform = NOISE
leads to inconsistent behavior on the Noise
Bandwidth of the output signal; The real-time noise
bandwidth on channel 2 is changed if an AM sine
modulation is switched on channel 1
h) Unable to install the IQ option before 30 trials run out

1. Support IQ waveform generated by customIQ of
SigIQPro;
2. Screenshot files support PNG and BMP formats;
3. MOD, SWEEP, BURST add RUN/Stop control function;
4. Support display of current output frequency during
frequency sweep;
5. Fixed the bug that the waveform is discontinuous when
the length of the sequence wave is not an integer multiple
of 16;
6. Enhance the sequence function, and the number of loops
of segment no longer occupies storage space multiple
times;
7. Delete the true arb mode of arb wave, and only keep the
DDS mode. The true arb mode is implemented by the
sequence (sequence with only one segment);
8. Solve the problem of abnormal output when the frequency
between 250MHZ and 300MHz during sweep;
9. Modify the default output polynomial of PRBS and support
programmable polynomial;
10. Sync output supports 50% duty cycle output mode;
11. IQ waveform information diaplay add data source
information;
12. Solve the problem of duty cycle is changed during
frequency change when square or pulse output;
13. Added a new DC output mode to solve the problem that
when changing the voltage, the output will jump to 0
before outputting. This method will reduce the output
accuracy;
14. Support amplitude sweep function.
