GUIDE TO ESTABLISHING TOTAL POWER DATA FOR LEVEL COMMAND Test equipment needed: low frequency absolute power meter 1. Open two windows and to current DATA and DESIGN directories 2. Disconnect all MF/DFB cable connections from MFs 3. In DESIGN window edit mf.cal 4. Connect noise source at -15 dBm to IF inputs 5. SETMF {n} {b} 31.5 CHECKMF -n 100 {n} Edit Imin,Qmin values into mf.cal table which has lines of "{n} {b} Imin Inom Qmin Qnom" SETMF {n} {b} {a} Adjust {a} above until power meter gives +0.0-0.5 dBm CHECKMF -n 100 {n} Edit Inom,Qnom values into mf.cal table which has lines of "{n} {b} Imin Inom Qmin Qnom" SYNTAX {n} is MF module number 0-11 {b} is low pass filter, e.g., 16e6 min is low level power nom is nominal level power {a} is attenuation setting REPEAT FOR ALL BANDWIDTHS, 16e6; 8e6; 4e6; 2e6; 1e6; 0.5e6 REPEAT FOR ALL MFs 6. Do "cat mf.cal | wc" and check for correct number of lines, 6 per MF 7. Save mf.cal as {s}{yymmdd}.cal. Repeat exercise once per annum and compare. Or if leveling in data is not accurately done repeat and inspect differences for source of "problem". 8. Run "cklevel" batch file which gives summary of {a}'s by {b} and MF in same order as mf.cal. These should "make sense" given identical IF noise incident on all MFs. Result is in cklevel.dat. An example from ABPP follows.
