Bikash, Yes, you are correct. All of our units return the values from the driver in ADC counts. The PS3424 will return the values normalized to 16 bits readings also. This is to make use of oversampling when you have it enabled. To convert the readings to voltage readings you can use the following f...

Chris, To remove the internal battery simply remove the 4) screws under the rubber tabs on the back of the unit. Separate the two halves and you will see the rechargeable battery. Simply unplug the connector to disconnect the battery. Regards, Richard Boyd Crag Technologies, Inc http://www.pc-oscill...

Hello,

How are you obtaining the values that are correct? Describe your testing setup for us so we can track down the source of the problem. Thanks!

gtfa, To get the peak and minimum decibel amplitude of the sound waveform you are going to have to run the signal though a FFT. The FFT is generated through the software as the PicoScope units export the raw data times and values. There are several sources of code available for the different types o...

gtfa, The auto range function is a procedure setup in the PicoScope software. This isn't unfortunately a function that the unit does automatically. You can write your own function in VB to achieve basically the same thing. Essentially, you have your program look at the ADC counts and if one of the c...

gtfa, The ADC-100 has a 12 bit ADC inside of it. The driver outputs the counts from this ADC with values ranging from 0-4095. 0 would be the farthest negative value and 4095 would be the farthest positive. So if you are on the ±20V scale 0 would be -20V and 4095 would be +20V. To convert the ADC co...

bmckenney, First off my apologizes, I seemed to have been mistaken/forgotten. The PS220x series AWG and External Trigger do function separately due to the fact that the the PS220x series there is in fact no external trigger. The signal out connector is strictly a signal out. I do apologize on this f...

bmckenney, The trigger and the AWG logic are independent of each other. However only one or the other may be used at the same time. This is due to them both using the same connector. If you are outputting a signal with the AWG on there is no way to input a signal back into this port to use it as an ...

Chris,

The LM35 reqiures a voltage supply of 4 to 30 volts. As the ADC-20 only operates at 2.5V you will need an external power supply to use it with the ADC-20.

bmckenney, 1) The AWG will start outputting the signal immediately after the function has been called. 2) A null value (0) entered into the sweeps parameter will make the AWG output the signal continuously when the start and stop frequencies are different. 3) The signal out connector after the AWG h...
