ENR File Format 5

ENR data

ENR data records must be ordered from the lowest to the highest frequency.
General form
The noise figure analyzer attempts to interpret lines which are not comments or
header fields as ENR data. ENR data has the general form:
Freq [Funit] ENR [Eunit] [Euncert [on_mag on_phase off_mag
off_phase [on_mag_uncert [on_phase_uncert off_mag_uncert
off_phase_uncert]]]]
Square brackets signify optional fields.
NOTE
Field separator
Each field is separated by whitespace. A single ',' is allowed within or instead of
the whitespace.
Numeric fields
With the exception of the two optional unit fields, the other fields are numeric.
Numbers are formatted as an optional sign, followed by a sequence of one or
more digits (which can include a single decimal point within the sequence),
followed by an optional exponent. The exponent consists of the 'e' or 'E' followed
by an optional sign followed by between one and three digits, for example, '10e6'
to represent 10 MHz.
Frequency fields
The frequency field (Freq) is the frequency at which the ENR amplitude was
measured.
The frequency unit field (Funit) is optional. The default unit is Hz.
Valid units are Hz, kHz, MHz, GHz, THz. Units are not case sensitive.
ENR fields
The ENR amplitude (ENR) is the measured ENR at the specified frequency.
