It contains several frequency series each 401 steps long separated by headers. See example header below: -------------------------------------------------------------------------------- Thu 03/May/2001 13:37:39 FRQRES P1 Density 1Mohm RF=1Mohm 8kHz ADC input Ref harness Source Amp -7.000 Freq. Amp 1 Pha 1 Amp 2 Pha 2 -------------------------------------------------------------------------------- The header is 3 lines and the - is not part of the header. Line1: Creation date Line2: Different parameters as follows: P1 Probe/Sensor 1 Density Density mode, also in file name abbreviated with _D_ 1Mohm This is the serial source resistance used during measurements. RF This is the feedback resistor on the amplifiers, thus the current gain. 8kHz Analog filters used ADC input Measurment path probe to ADC input Ref harness Means the reference harness was used. Source Amp Gives the amplitude of the frequency source/[dBm] Line3: Column descriptions, note Amp 2 and Pha 2 is not used. Freq Source frequency/[Hz] Amp1 Amplitude/[dB] Pha1 Phase/[Degrees] After the header comes 401 lines of data, then a new header and new data and so on. " END_OBJECT = ASCII_DOCUMENT END
