Calibration
From Physics 111-Lab Wiki
Calibration Procedure for Electronics on Muon Lifetime
Use the DG535 digital Pulser and the Power Splitter ZSCJ-2-1.
Setup the DG535 as follows: (Manual available on 111-Lab Network Drive.) or The manual is available online: http://www.thinksrs.com/downloads/PDFs/Manuals/DG535m.pdf.
- TRIG:
- INT
- Rate = 20kHz
Step through the delay menu setting the following settings;
- Delay =
- A =T+ 0.000001 ( 1usec)
- B=A+ 0.000000150 (150nsec)
- C=T+ 0.000000250 ( 250nsec)
- D=C+ 0.000000250 (250nsec)
Step through the Output menu setting the following settings;
- OUTPUTS =
- TO: = Load = 50 ohms
- Select VAR
- TO: Amplitude = +2.00V
- Offset = 0.00V
- TO: = BUR
- Rate = 10kHz
- Pulse/Burst = 10
- Period/Burst = 20
- Slope = +/-
- EXT:
- Threshold = +1.00V
- Trigger Term = HighZ
- A: Load = 50 ohms
- Select VAR
- A: Amplitude = +2.00V
- A: Offset = 0.00V
- B: Load = 50 ohms
- Select VAR
- B: Amplitude = +2.00V
- Offset = 0.00V
- AB&-AB: Loads = HighZ
- Select VAR
- AB: Amplitude = + 2.00 V
- AB: Offset = 0.00V
- C: Load = HighZ
- Select VAR
- C: Amplitude = +2.00V
- C: Offset = 0.00V
- D: Load = HighZ
- Select VAR
- D: Amplitude = +1.00V
- D: Offset = 0.00V
- CD&-CD = Loads = HighZ
NOTE: Do Not Set Offset negative or great than 0 Volts, You will blow out and damage the amplifier.
Setup of cable Hookup for Calibration Run
- Output of DG535 Pulser “AB Plus” hooked to the Power splitter input label 2
- Muon signals through the amplifier at 40 dB and through the Inverter then to the power Splitter input label “1”.
- Output of the Power Splitter output label “S” to the input channel #1of the Computer Digitizer Card NI-5114.
