Raw ADC values are the raw 16 bit ADC levels in ASCII format The channel s gain and offset are needed in order to obtain the signal level in Volts The required information to convert the Raw ADC values to voltage is included in the header information of each Raw ADC ASCII file or in the awh file accompanying the binary files In order to convert the Raw ADC values into Volts the following formula should be used V vGain data vOffset The Amplitudes V selection stores the waveforms as voltage samples in ASCII format This data has already been adjusted for gain and offset and can be directly read out as a voltage However it requires roughly twice as much space as Raw ADC value data For the sequential acquisition mode the segment time stamps are also stored when waveforms are saved using the Autostore and Save Waveform functions Data stored in binary format with Autostore must be converted before it can be imported into a data processing package or a spreadsheet e g Data formal M PIS ES Excel The Data Format Conversion option is found under the Store menu Source folder Select Data Format Conversion in order to bring up the following window fesAcqiisLive Data Browse The acquisition must be stopped in order to access this menu a 3 To convert the binary data simply select the source folder where the data fe Amplitudes V Segments as columns is located select the output format and click OK
