  1. AMY@Lecce: what is new? Auger Lecce Meeting, 21-03-2011 AMY Meeting. 21 Mar 2011

  2. AMY- tests in Lecce AstroParticle Lab Signal Generator R&S SMB100A 9kHz to 3.2GHz Power Detector ZX47-60-S+ containing AD8318 Using Oscilloscope - RT LeCroy (3GHz) Signal from Generator 1.7 GHz RF frequency -40 dBm level 150 ns pulse width 1.7 GHz RF frequency -30 dBm level 150 ns pulse width AMY Meeting. 21 Mar 2011

  3. AMY- Power Detector Signal Vs Pulse Width SEGNALE 10 ns0 50 ns0 TRIGGER 100 ns0 150 ns0 AMY Meeting. 21 Mar 2011

  4. Power Detector(ZX47-60-S+) Time response INPUT Signal • Signal Pulse Width from 10 nsec to 200 nsec • 2 different frequencies (1.7 GHz and 2.6 GHz) OUTPUT Signal ( PeakToPeak measure) The power detector seems fully efficient only for signals having a pulse > 100 nsec A similar temporal behaviour on rise/fall. • Rise Time > then specifications AMY Meeting. 21 Mar 2011

  5. XX % DT Power Detector(ZX47-60-S+) Time response Using different couplings in input from the oscilloscope DT • Fall time for a signal level of XX% around the half • amplitude: • 80% from 10% to 90% • 70% from 15% to 85% • ….. • 10% from 45% to 55% DT AMY Meeting. 21 Mar 2011

  6. Power Detector from Maxim Time response home made evaluation board INPUT Signal • Signal Pulse Width from 10 nsec to 180 nsec • 3 different frequencies (1 1.7 GHz and 1.9 GHz) OUTPUT Signal ( PeakToPeak measure) The power detector seems fully efficient for signals having a pulse > 40 nsec Very much dependent from input RF (see next slide) AMY Meeting. 21 Mar 2011

  7. Power Detector from Maxim INPUT Signal • Signal Pulse Width 100 nsec • scan in frequencies: • from 0.9 GHz to 3 GHz • scan in signal amplitudes: • from -90 dBm to -30 dBm AMY Meeting. 21 Mar 2011

  8. From last meeting: • Small acquisition set-up eventually for acquiring directly • the LNB (around 1 - 3 GHz). (using the LeCroy) • Investigating other Power Detectors and/or different evaluation boards. • 2 more from AD as the one we have in order to modify the board (not working) • Power Detector from Maxim with larger dynamic range (home made evaluation board) (DONE) • Trying to understand the time response – 2 more PD in the lab. • FADC-> to be ordered • More LNBF on different bands (C, Ku). More done/to do: • Embedded CPU for VME working. • Programming for TDC aquisition. • Investigating the 2 Power Detectors now in the lab, mods in the board for the time response investigation. • Switch on the LNBF • Antenna for S Band (to be finalized) • Linearity of PowerDetector • Power Supply (for the AMY test Beam) AMY Meeting. 21 Mar 2011
