UChar_t RawAnitaHeader::bufferDepth

Buffer depth.

The lowest two bits (bufferDepth&0x3) are a two-bit number (with range 0-3) that count the number of held buffers at the time of the trigger.

The next lowest two bits (bufferDepth&0xc)>>2 are a two-bit number (with range 0-3) that count the number of held buffers at the time of readout.

Definition at line 165 of file RawAnitaHeader.h.

UShort_t RawAnitaHeader::calibStatus

Calib/Relay Status.

Here we are coutning bits from 1 to 16

"Bit 1" 1st RFCM relay on/off
"Bit 2" 2nd RFCM relay on/off
"Bit 3" 3rd RFCM relay on/off
"Bit 4" 4th RFCM relay on/off
"Bit 5" Naidr RFCM relay on/off
"Bit 6" GPS relay on/off
"Bit 7" Cal Pulser relay on/off
"Bit 8" Unused
"Bit 9" RFCM Switch Port D
"Bit 10" RFCM Switch Port C
"Bit 11" RFCM Switch Port B
"Bit 12" RFCM Switch Port A
"Bit 13:16" Attenuator Setting

For the attenuator setting take (calibStatus&0xf000)>>12 and:

-  "Value 7" 0th Attenuator setting (0dB)
-  "Value 3" 1st Attenuator setting (3dB)
-  "Value 5" 2nd Attenuator setting (8dB)
-  "Value 1" 3rd Attenuator setting (12dB)
-  "Value 6" 4th Attenuator setting (18dB)
-  "Value 2" 5th Attenuator setting (22dB)
-  "Value 4" 6th Attenuator setting (28dB)
-  "Value 0" 7th Attenuator setting (33dB)

UShort_t RawAnitaHeader::deadTime

Dead Time.

The number of of 16.384 us clock ticks in the current second, upto triggerTimeNs ns, which all four buffers were full. A more consistent definition of deadTime is available in the TurfRate class.

Definition at line 158 of file RawAnitaHeader.h.

UChar_t RawAnitaHeader::errorFlag

Error Flag.

Here we are coutning bits from 1 to 8

"Bit 1" means sync slip between TURF and software
"Bit 2" is sync slip between SURF 1 and software
"Bit 3" is sync slip between SURF 10 and SURF 1
"Bit 4" is non matching TURF test pattern
"Bits 5-8" reserved (currently zero)

Definition at line 94 of file RawAnitaHeader.h.

UInt_t RawAnitaHeader::eventNumber

Software event number

Definition at line 51 of file RawAnitaHeader.h.

UChar_t RawAnitaHeader::otherFlag

Currently the first two surf evNums

Definition at line 84 of file RawAnitaHeader.h.

UShort_t RawAnitaHeader::ppsNum

Number of GPS PPS since last clear all

Definition at line 153 of file RawAnitaHeader.h.

UShort_t RawAnitaHeader::prioritizerStuff

Prioritizer stuff.

Here we are coutning bits from 1 to 8

"LSB" Polarisation 1 is VPol
"Bit 2-11" is peak phi bin
"Bit 12 unused"
"Bit 13 is filtering flag - above max power"
"Bit 14 is filtering flag - bin-to-bin increase"
"Bit 15 is saturation flag"
"Bit 16 unused"

Definition at line 129 of file RawAnitaHeader.h.

UChar_t RawAnitaHeader::reserved[2]

Reserved bytes — Deprecated.

The lower four bits of the first byte (reserved[0]&0xf) show the TURF hold issued for this trigger. There should be only one buffer held per trigger and it should match the SURF labrador readout for the event. Here we are coutning bits from 1 to 4

"Bit 1" is hold 1 (buffer A)
"Bit 2" is hold 2 (buffer B)
"Bit 3" is hold 3 (buffer C)
"Bit 4" is hold 4 (buffer D)

The upper four bits of the first byte (reserved[0]&0xf0)>>4 show which TURF holds were acitve when the trigger was formed. The bits have the same meaning as above. It is possible to have all holds active (in which case there are no free buffers and the trigger is dead until a buffer becomes available).

The second byte (reserved[1]) is currently reserved.
