Comments:
NOTE NOTE NOTE NOTE
This is a non-standard setup including
- USB/LSB DAS profile
- Turn noise cal off
- Turn DAS Gain loop off
- Turn phasecal off if present
Disabling Noise Cal
ATCA: type "set diode off" in caobs
Mopra: In attest under "noiscl", select "LSNoise" to off . (to confirm with Tasso)
Parkes: pkmc -> "Cal Control Unit" -> select current Rx on matrix and set to "off"
Disabling Noise Cal (ATNF DAS GUI)
- Adjust external attenuation so that the IF level is approx mid band
- Select "Details" under "Monitor View"
- Monitor the "Level" value for IFP#1 and IFP#2 and estimate a time averaged value (Tid only needs to worry about one IFP)
- Record the two average level values
- Under "Config Sftw" select "Filters --> Band Spliter"
- Set "Gain Control" to Manual for both IFP (in the lower right region under "Statistics"
- Set the two Gain levels to 4*(255-Level) where level is the value to measured above
- Click the "Config Hdw" button
- On the "Details Monitor view' display check the Level is ~ 128
- Adjust the attenuation if the level wanders away too much from 128 - each number is ~ 0.1dB.
- Monitor VLBI sampler statistics stay around nominal 17.3%/32.7%
