Hi all, I'm using two analog inputs of a DI-148U to measure DC voltages. The voltages range from 0 to +5 volts. The DI-148U is specified as having an input...
Hi Mke If I read you right you may be asking a bit much of the device. You cannot invoke methods like PGain(index) as that would only apply to units having...
Thanks for the help, Ron. What I will probably do is amplify the analog to expand my voltage to the +/- 10 volt range., then divide the digital result. I...
Hi Mike Just a few more details. Thinking of a good way to explain this. OK with a 10 bit device like the DI-148 you have a fixed voltage range of -10 to 10...
Mike I am sorry as in my last email I missed the last part of your question: "Also- is there an easy way of averaging a bunch or readings using UltimaSerial...
Ron, I did do some averaging by taking 40 ADC readings, adding them to the variable, and then divided the result by 40. After giving it some thought- I'm not...
Newbee here. I'm trying to use the Ultimawaterfall activeX control in a Visual Studio 2005 (Visual Basic) program to display a spectrogram. My problem is with...
Hi, I am new to the forums here. I need help. I am trying to convert the data from UltimaSerial.GetData() and integrate them as peaks. With these peaks I am...
Since only on trigger condition is available, you may need to track the data yourself. For example, you may use the trigger mode to start the data stream at...
I see posts for setting the direction of all digital IO to in or out, but I can't find a post that explains how to set one to out and one to in. Also, can...
See http://www.ultimaserial.com/standard.html#SetDIODir: It is plain binary format, bit 0 for DIO0, bit 1 for DIO1.... In case you are not familiar with...
I'm using a 148U to capture descrete readings from a hand held probe. The analog single provides a running graph of the output which will let me see when the...
To use D0's state as the storage control, you can use Digital0 as trigger channel and set the trigger mode to WhenAboveLevel: Dim buffer(1000) As Integer Dim...
Whoa! This is over the top. I did a work around in the meantime, but this sure opens possibilities. Thank You!!! ... available ... points. ... 3276.8, ... ...
With the latest version and the following codes, you may log one data point, along with timestamp, to the excel sheet whenever D0 goes high: Private Sub...

Due to the limitation of FFT1024, it was not easy to study low level signal with Windaq Spectrogram and FFT Add-ons A remedy is provided per user request: A...

I am using VB6 to capture a 60 Hz sine wave at a sample rate of 12288. I am using a 120V outlet (with a DI-730) for testing. The sampled data goes through...
