Hi @Andy-205
The solder shapes looks good but you could try to resolder TP1/3, add a bit of new tin/flux to it.

Hi @miketranch
Unfortunately your pictures are not available.
GND pins are available on the BNC header.
USB isolator can be used for safety and noise reduction from computer or ground loops. The cheaper ones provide only USB FS 12Mbps but even this is fine for average usage. Slowdown is noticeable with large captures or data streaming, or high capture rate is desired. -

Make sure the USB and power cables are fully plugged in, try using a different USB port on your computer, cable, different computer...Other application or computer performance should not cause transfer error.
WaveForms application can be used even on low performance single board computers. On these, the slowdown is felt when capturing or streaming lots of samples and/or performing hungry post-processing or views. -

For long transfers maximum is about 10MHz:
55 minutes ago, attila said:When transferring more bits than the Logic Analyzer device buffer, the data need to be streamed over USB, with AD3 the max rate is about 10Msps.
Rate is for the loop function:
It is not possible, each of the 16 DIO channels has its own 32ki buffer.

Hi @jostikas
Could you attach or send me in private message your workspace ?

Hi @Ola
In each loop iteration you want to transfer 32 times 24 bits with a clock rate of 6.25MHz. This can be done with a loop rate of at most 7.8kHz = 6.25MHz / 32 / (24+1?) ? because it depends on the specified delays.
The 5th AD3 configuration allocates 32ki logic and pattern buffer. For each bit it needs 2 or 4 samples, 32768/2/25, so N can be up to about 650.
When transferring more bits than the Logic Analyzer device buffer, the data need to be streamed over USB, with AD3 the max rate is about 10Msps.

Hi @Denspa
The WaveForms application uses by default the system's default fixed font scripts but it can be changed in under Settings/Options
The latest version uses UTF-8 in most text save/load of the application:

Hi @David Wells
This is most likely a connection issue, the same error is reported on USB disconnect or device power toggle.
Make sure the USB and power cables are fully plugged in, try using a different USB port on your computer, cable, different computer...I don't know which software version you are using. Here you can find the latest:

Hi @Denspa
Wavegen = Wavegen1
The index is because it allows you to open multiple instances of most instruments. -
Hi @Denspa
It is not supported but you can set custom data for the instruments traces/channels, from the Script tool or from View/Logging/Script like: Spectrum.Trace2.setMagnitude(...

Hi @Ola
The oscilloscope channels of AD1,2,3 have two input ranges, 5V and 50V. At 10V the ADC is used at about 11.5bits

Hi @Ola
The Write/CmdWrite only writes to D0, like:
CmdWrite(8, 0x10, 0, 16, [0x0001]); // write 0x0001 to register 0x10
and for Read0
CmdRead0(8, 0x10, 0, 16, 1); // read one 16bit word from register 0x10The read/write functions activate CS during the transfer with hardware timing.
You can also use the Start/Stop functions for software CS control but this will take more time (like +1 millisecond) and this is also reflected in CS edge to bit transfer timing.

Hi @fizzbang
The Channel 1 curve shows low impedance at low frequencies exceeding the AWG output drive capability, dropping the output voltage significantly.
The phase can only have a range of 360*, adjust the offset for this. -

Hi @yattr
The next version will show value for remaining/less bits than specified. It will also add 'bit label' option.
The decoded values are listed in the Events view. Click to highlight in plot, or modify Select mode, or double-click for positioning.

Hi @Empower
The digital-in sampling rate is determined by internal-clock/divider, so for 100MHz set the divider to internal-clock/100MHz

Hi @Oliver
For 50R termination you could use a T splitter and 50R terminator.

Hi @infield
The trigger event is by default the rising edge of the trigger signal, but it can be configured to be the falling or either edge.
An instrument's trigger output is high while in Run state.
By default the run time is continuous in Wavegen and Patterns, so these will toggle their trigger outputs when started or stopped.
