Date: 04/21/2010 @ 06:07 PM Hybrid: H37 Temp.: room Operator: VRR & HM Summary: 1) DC per-pixel tests 2) ADC integral linearity 3) Normal mode threshold 4) CP mode pixel transfer function/noise Procedure: 1) Install hybrid to position A and ensure 1x probe attached at position A "scope out". Apply black cover to block light. (Leave positions B, C, and D empty.) 1.2) Record hybrid serial number ________. H37 1.5) Create a folder within the Win32For directory name "H###" to hold the test data. 2) Start Win32For by double clicking desktop icon. Load "talk" program using "fload talk-com4+". Prepare to boot MISC by typing "talkk" DO NOT PRESS ENTER YET!! 2.5) Make sure meters are on at "2A" setting. 3) Apply power by turning on power strip switch. 4) Record currents: |----------+-------+-------+-------+-------+-------+-------| | meter: | 8V | 12V | -12V | 1.5D | 1.8D | 3.3 V | |----------+-------+-------+-------+-------+-------+-------| | nominal | 0.028 | 0.003 | 0.011 | 0.025 | 0.000 | 0.032 | | measured | 0.025 | 0.003 | 0.011 | 0.026 | 0.000 | 0.032 | |----------+-------+-------+-------+-------+-------+-------| 5) Boot MISC by typing a "carriage return" (enter) to execute previously typed "talkk" 6) Open a log file using ^G and specify the filename "pixeldc_HXXTTTC.txt" in the data folder "H###". 7) Load files md00.txt through md07.txt into MISC using ^A command. Files are in directory C:\cygwin\home\miyasaka\work\misc\asictest4-12-10\md 8) On the MISC execute "PIXELDC". This test takes 10 minutes. Log start time in notebook. Wait for "DONE", then close the log file with ^G. 9) Exit the talkk program by typing "esc". 9.5) Record currents: |----------+-------+-------+-------+-------+-------+-------| | meter: | 8V | 12V | -12V | 1.5D | 1.8D | 3.3 V | |----------+-------+-------+-------+-------+-------+-------| | nominal | 0.022 | 0.003 | 0.011 | 0.026 | 0.010 | 0.040 | | measured | 0.021 | 0.003 | 0.011 | 0.026 | 0.010 | 0.039 | |----------+-------+-------+-------+-------+-------+-------| 10) In Win32For window execute "intlin". This test takes ~2 minutes. 11) After "intlin" finishes, execute "talk" and open a log file using ^G. Name it "intlin_HXXTTTC.txt" in the data folder "H###". 12) On MISC execute "300 5 MEANS@", then close log file. 12.5) Need to change the value of "VPL2SEL" at -15 C use "9 VPL2SEL ! CMD!" at 0 C use "10 VPL2SEL ! CMD!" at 40 C use "12 VPL2SEL ! CMD!" for room temp, the default value (11) is fine. no change necessary 12.6) check value "VPL2SEL ?" 11 13) Exit "talk" using "esc".In Win32For window execute "ndisctest". Specify the log file to be "disc_HXXTTTC.txt" in the data folder "H###". Wait for "log file closed ok". test takes ~50 minutes. Log start time in notebook. 14) In Win32For window execute "talk". 15) On MISC execute "GO", then "SWCNTS." a few times to verify event processing. 17) On MISC execute "ALLON ECMD!" and "SWCNTS." 17.5) If output of "SWCNTS" NEV and NTPTRIG are not similar (~190) then raise the threshold. "75 DS!" ("DISCSET ?" to check current value) 18) On MISC execute "EVOFF CPMODE EVON" and "SWCNTS." 18.5) On MISC execute "1 SCOPSEL ! ECMD! " to observe preamp output. 19) From probe station test of this ASIC find the optimum value of 4VSEL and record ________. 50 NOTE: The value for 4VSEL for H37 is 32 in Kadmos. With this value the amplitude of sawtooth for (0,0) is about 90 mV and for (31,31) it is about 40 mV. 4VSEL being 50 seems to be more reasonable with both pixels having amplitude of about 50 mV, so set 4VSEL at 50 for H37. 20) On MISC set the variable 4VSEL to the optimum value using "### 4VSEL ! ECMD!". 21) On MISC execute "EVOFF 0 0 XYSEL EVON" and view sawtooth on scope. 22) On MISC execute "EVOFF 31 31 XYSEL EVON" and compare sawtooth to that for pixel 0,0. 23) do "esc". In Win32For window execute "pixslin". Specify the binary file to be "pixslin_HXXTTTC.bin" in the data folder "H###". Wait for "binary file close ok". (about 3 hrs) 24) Turn off power strip for power supplies (behind oscilloscope) 25) close Win32Forth window.
