Parameter block layout
ESR data format
Data is recorded in the matlab4 data format and consists of several blocks:
- the experiment info, d_ExpInfo (ASCII string)
- the antenna parameters (see below), d_parbl (32 bit reals)
- the data, d_data (2×32 bit complex reals)
- the raw samples (not always present), d_raw (216 bit complex integers)
- Bit 65-74 is different depending on system
- Antenna ID parameter 41:
1 32m ESR
2 42m ESR
3 VHF
4 UHF
5 Kiruna
6 Sodankylä
8 32p ESR - ESR parameter 67
0 SPEAR all tx off
1 SPEAR low power radar
2 SPEAR high power radar
3 SPEAR heating - ESR parameter 68
0 Lower plasma line LO1 set to 492 MHz and upper plasma line LO1 to 502 MHz
1 Lower plasma line LO1 set to 496 MHz and upper plasma line LO1 to 502 MHz
2 Lower plasma line LO1 set to 492 MHz and upper plasma line LO1 to 506 MHz
3 Lower plasma line LO1 set to 496 MHz and upper plasma line LO1 to 506 MHz
- UHF parameter 67 (not available at UHF remotes) and VHF parameter 72 gives the power status on the Tromsø¸ systems as follow:
Bit 0 UHF RF on
Bit 1 UHF HV on
Bit 2 UHF power on
Bit 3 VHF RF on
Bit 4 VHF HV on
Bit 5 VHF power on
Bit 6 Heating RF on
Bit 7 Heating power on - VHF parameter 69 are decoded as follows:
bit 0:1 Antenna phasing
0 allB
2 allA
3 splitbit 2:5 IF setup
bit 2 lo1/chI 0 298 MHz 1 290 MHz
bit 3 lo1/chII 0 298 MHz 1 290 MHz
bit 4 lo2/chI 0 84 MHz 1 78 MHz
bit 5 lo2/chII 0 84 MHz 1 78 MHzPositive logic Note these values are integers
