# Frequency definition table. Version 1.0 Format of 2024.02.10 # # Created by L.

The frequency range is defined here as the range that software # supports. Setting frequencies beyond the specified range will cause # signal corruption. The usable frequency range may be more restrictive # than the available range due to the internal or external radio interference. # # A wiring describes physical cable connection that is not controlled # by software and a specific firmware of the digital backend. # A given station may have more than one wiring. A change of wiring # requires re-connect cables and/or flushing firmware. # # Bands are named alphabetically in this file and may not coincide with # internal band names supported by the antenna control software. # # Format: # STA_NAM -- two-character long station name # WIRING -- wiring name # BNAND -- band name # LOW_FRQ -- Low frequency of the range in MHz # HIGH_FRQ -- High frequency of the range in MHz # FRQ_STEP -- Frequency step in MHz # DAS -- data acquisition terminal # LO_TYP -- type of lo computation # a -- LO is hard-corded in the LO field # b -- LO = If1 - 512.0 - Bw/2 # c -- LO = If1 - 512.0 + Bw/2 # d -- LO = ?? # IF_TYP -- type of IF computation # a -- IF = LO + offset # b -- IF = LO + 1008 - k*32.0, where k is integer # c -- swapped lsb/usb # LO -- LO frequency in MHz # # #Sta wiring band Freq_low Freq_high fs backend lt ft lo_freq # Bd iaa_01 A 8080.0 9104.0 0.01 mark5b_geo2 a a 8080.00 Bd iaa_01 B 2200.0 2400.0 0.01 mark5b_geo2 a a 2020.00 Bd iaa_01 C 0.0 0.0 0.01 mark5b_geo2 a a 0.00 nop Bd iaa_01 D 0.0 0.0 0.01 mark5b_geo2 a a 0.00 nop # Ft ft_01 A 8100.0 8560.0 0.01 mark5b_geo4 a a 8080.00 Ft ft_01 B 8500.0 8960.0 0.01 mark5b_geo4 a a 8580.00 Ft ft_01 C 2200.0 2400.0 0.01 mark5b_geo4 a a 2020.00 Ft ft_01 D 2200.0 2400.0 0.01 mark5b_geo4 a a 2020.00 # Fz udc_01 A 2028.0 5000.0 0.00004 r2dbe b b Fz udc_01 B 4000.0 15020.4 0.00004 r2dbe b b Fz udc_01 C 4000.0 15020.4 0.00004 r2dbe b b Fz udc_01 D 4000.0 15020.4 0.00004 r2dbe b b # # Email from Johnathan Quick on 2025.04.23 # # DBBC3 inputs are natively 0-4096 MHz with an optional tunable down-conversion # ahead of that.

The RF bandpass filters are in the range of # 3-7, 6-10 and 9.5-13.5 GHz. There is some ability to go outside of this # range but the sensitivity declines rapidly more than 200 MHz away from # the nominal band edges. The LO in use can be changed during an experiment # (in the range of either 6-9 GHz for IFs A-F or in the range of # 9-12 for Ifs G/H) but this will likely cause a clock break and may affect # the input IF through aliasing. Changing USB/LSB mixing is fine, as long # as aliasing isn't introduced. # # We try to avoid the extremes of the 0-4096 MHz IF (i.e above 100 and # below 4000 MHz). The DBBC3 incorporates a low pass filter which reduces # the amplitudes for IF frequencies > 3.5 GHz but this doesn't radically # affect amplitudes. # Hb au_01 A 3000.0 6900.0 0.1 dbbc3_v a a 7000.0 Hb au_01 B 3000.0 6900.0 0.1 dbbc3_v a a 7000.0 Hb au_01 C 6010.0 10800.0 0.1 dbbc3_v a a 6000.0 Hb au_01 D 9600.0 13580.0 0.1 dbbc3_v a a 9500.0 # Jl jl_01 A 4000.0 9000.0 0.1 cdas a a Jl jl_01 B 4000.0 9000.0 0.1 cdas a a Jl jl_01 C 0.0 0.0 0.01 cdas a a 0.0 nop Jl jl_01 D 0.0 0.0 0.01 cdas a a 0.0 nop # K2 udc_01 A 2200.0 5000.0 0.4 rdbe b b K2 udc_01 B 4000.0 13506.4 0.4 rdbe b b K2 udc_01 C 4000.0 13506.4 0.4 rdbe b b K2 udc_01 D 4000.0 13506.4 0.4 rdbe b b # Ke au_01 A 3000.0 6900.0 0.1 dbbc3 a a 7000.0 Ke au_01 B 3000.0 6900.0 0.1 dbbc3 a a 7000.0 Ke au_01 C 6010.0 10800.0 0.1 dbbc3 a a 6000.0 Ke au_01 D 9600.0 13580.0 0.1 dbbc3 a a 9500.0 # Kk kk_01 A 8100.0 8600.0 0.01 mark5b_geo5 a a 7600.0 Kk kk_01 B 8600.0 9100.0 0.01 mark5b_geo5 a a 7600.0 Kk kk_01 C 8100.0 8600.0 0.01 mark5b_geo5 a a 8100.0 Kk kk_01 D 7600.0 8100.0 0.01 mark5b_geo5 a a 6600.0 # # Email from Michele Paradiso of 2025.06.04_12:19 # Mb mb_01 A 2100.0 4000.0 0.01 dbbc3_v a a 0.0 Mb mb_01 B 3600.0 7600.0 0.01 dbbc3_v a a 7700.0 Mb mb_01 C 3600.0 7600.0 0.01 dbbc3_v a a 7700.0 Mb mb_01 D 7600.0 11600.0 0.01 dbbc3_v a a 11600.0 # Mc mc_01 A 8100.0 8820.0 0.01 mark5b_geo4 a a 8080.00 Mc mc_01 B 8100.0 8820.0 0.01 mark5b_geo4 a a 8080.00 Mc mc_01 C 2100.0 2400.0 0.01 mark5b_geo4 a a 2020.00 Mc mc_01 D 2100.0 2400.0 0.01 mark5b_geo4 a a 2020.00 # Mg udc_01 A 2200.0 5000.0 0.4 rdbe b b Mg udc_01 B 4000.0 12498.0 0.4 rdbe b b Mg udc_01 C 4000.0 12498.0 0.4 rdbe b b Mg udc_01 D 4000.0 12498.0 0.4 rdbe b b # Nn nn_01 A 2100.0 4000.0 0.1 dbbc3 a a 0.0 Nn nn_01 B 3600.0 7600.0 0.1 dbbc3 a a 7700.0 Nn nn_01 C 3600.0 7600.0 0.1 dbbc3 a a 7700.0 Nn nn_01 D 7600.0 11600.0 0.1 dbbc3 a a 11600.0 # # This setup is not used after 2023.08.05 # Ns ns_01 A 8100.0 8592.0 0.1 mark5b_vdif a a 8080.0 Ns ns_01 B 8592.0 9104.0 0.1 mark5b_vdif a a 8080.0 Ns ns_01 C 2200.0 2400.0 0.1 mark5b_vdif a a 1700.0 Ns ns_01 D 2200.0 2400.0 0.1 mark5b_vdif a a 1700.0 # # Mode ns_02 is for tests only.
