[pb with Digital Discovery too sensitive to glitchs on CSelect]

Hi @samuel.cregut

Make sure you have good ground connection between devices and the digital voltage is set to proper value, twist signal wires with ground...

[Problem with aquisition mode Record]

Hi @ssm

You should already have the examples installed, see:

[Analog Discovery 2 Waveform Generator Idle State as end voltage]

Hi @jerry iii

Select Independent or Synchronized, Idle:Hold, Run:Auto, Repeat:1
Adjust anything to return to Ready state, for initial output, or uncheck Enable for 0V output.

[How to save acquisition file directly on 2Gbit DDR3 of Digital Discovery using Python?]

Hi @Mavitaka

The 'Record to File' in the WaveForms application is improved in the latest version.
For Python examples see WF SDK/ samples/ py
Transferring 256MB over USB with 40MBps takes about 7 seconds.

[How to do Impendance Analisis for frecuency 0]

Hi @latot

See the Averaging setting in the front for minimum time per step and the Average under Options to specify number of captures to average, and you also have 'Min.Periods' 
DC is available in Meter mode or you can use Scope with Math channel.

Hi @Denspa

Try a newer version, 3.21.21 is the latest for armhf

 

[Is the sample rate and sample size adjustable within waveforms for the AD2?]

Hi @Michael Bradley

[SDK (Python) PWM duty cycle and frequency measurement]

Hi @mjelec

The samples represent levels for DIO channels 0 to 15
When a channel is left floating, the high impedance input can capture radiation, specially transitions from nearby wires or channels, or the grid's 50/60Hz
Mask the channels you are interested in, like for DIO-0 : rgwSamples[i]&1

[Logic Detector as trigger in Scope. Is it possible?]

Hi @m72

Thank you for the observation.
This version expects a return in the last line or something that it can return... I wanted to have this rule for some (math, measurement...) scripts, unfortunately it is applied for all scripts in the app.
This should work:

// Find I2C devices
// array to store the present adresses
var rgadr = [];
if(Clear()!=true)  return "I2C bus error. Check the pull-ups.";
for(var i = 8; i < 120 && wait(); i++){
    //Write(address) return true when acknowledged
    var f = Write(i);
    if(f == true) rgadr.push("0x"+i.toString(16));
}
if(rgadr.length) return rgadr;
return "No I2C device found";

 

[X measurement lines in zoom screen]

Hi @zelle

The next version will add cursor indicators to zoom views.

[Missing digital scope when using unusual time base]

Hi @zelle

With odd base the digital can be auto-set to lower rate than the analog and it takes more time for the digital to complete the capture. At higher base this difference can be significant and the instrument does not wait for the digital capture.
Thank you for the observation. It will be fixed in the next version.
(The bug was introduced when adding dual device support.)

Hi @Denspa

[Trigger Condition is not stored correctly in WaveForms]

Hi @zelle

The inputs are saved as user selected after leaving the field or on enter. The "Digital" button does not have focus.
If you select a trigger source and press the 'Digital' button the earlier selection does not get saved and last validated selection is loaded. After selecting a source press tab, enter or click in other place.
This behavior will be corrected in the next version.

[DD Manchester Hex display]

Hi @yattr

This is a feature and not a bug. Indicates the actual starting position of the data bit.

[No constant type in Waveforms API]

Hi @sand

The easier is to use Digital/StaticIO functions.
For constant with DigitalOut use Counter 0|0 and specify (initial) value with CounterInit

dwf.FDwfDigitalOutEnableSet(hdwf, channel, 1)
# dwf.FDwfDigitalOutIdleSet(hdwf, channel, DwfDigitalOutIdleInit) # default value
dwf.FDwfDigitalOutCounterInitSet(hdwf, channel, 1, 0) # 1 = initialize with high when running
dwf.FDwfDigitalOutCounterSet(hdwf, channel, 0, 0) # low/high count zero, no toggle during run, constant

You could use the killapp argument for safe close.

[How to export the osciloscope data in a long time measurememnt.]

Hi @Franchis

It can be done with the Script tool but it is easier and more precise to use a dummy Pattern or Wavegen for hardware timer (Run: 30min).
In Scope set Trigger: Normal, Source: in the respective instrument and use the Logging tool for auto export.

 

The next software version push the Update rate limit from 10s to 1hr.

Which software version are you using?

Hi @Ronnie

Unfortunately no. Industrial grade equipment would require not only the FPGA but all the components and the entire device certified for this.
