    DESCRIPTION         = "
This file contains frequency response from sensor/probe 1 to the ADCs.
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.
