5 ENR File Format
The ENR unit field (Eunit) is optional. The default unit is dB. Currently, the only
allowed unit is dB. Note that units K, C, F (temperature) are reserved for possible
future use, but are not supported by the noise figure analyzer at this time.
The uncertainty field for the ENR amplitude (Euncert) is optional. However, this
field must be present if reflection coefficient data is supplied.
Reflection coefficient data
The reflection coefficient data is optional and is formatted as four fields
(on_mag, on_phase, off_mag, off_phase):
– reflection magnitude with SNS series smart noise source on
– reflection angle (in degrees) with SNS series smart noise source on
– reflection magnitude with SNS series smart noise source off
– reflection angle (in degrees) with SNS series smart noise source off
If any reflection coefficient data is supplied, then all four fields must be present.
The file format requires the ENR uncertainty field to be present before any
NOTE
reflection data.
The reflection coefficient uncertainty (on_mag_uncert) is an optional parameter.
Either one or four reflection uncertainties are allowed. If one value is supplied, it is
assumed to apply to all reflection parameters. Alternatively, uncertainties can be
supplied for all four reflection parameters independently. Reflection coefficient
data must be present if this field is supplied.
