nenupy.instru.instrument_tools.instrument_temperature

nenupy.instru.instrument_tools.instrument_temperature(frequency=<Quantity 50. MHz>, lna_filter=0)[source]

Instrument temperature at a given frequency. This depends on the Low Noise Amplifier characteristics.

Parameters:

frequency (Quantity) – Frequency at which computing the instrument temperature. Default is 50 MHz.
lna_filter (int) – Local Noise Amplifier high-pass filter selection. Available values are 0, 1, 2, 3. They correspond to minimal frequencies 10, 15, 20, 25 MHz respectively. Default is 0, i.e., 10 MHz filter.

Returns:

Instrument temperature in Kelvins

Return type:

Quantity

Warning

For the time being, only lna_filter values 0 and 3 are available.

Example:

from nenupy.instru import instrument_temperature
import astropy.units as u

instrument_temperature(frequency=70*u.MHz)
