# Regular Meeting (2020.8.24)

1. Test circuit for switch
2. Test ibert with optical moduld on VCU108(10 days)
3. Idea to reduce the reset rate of transceiver

## 1. Test circuit for switch

I think that problem is caused by probe, as following experiment

### 1.0 Environment for test

### 1.0.1 Probes/Wires

* Probes-1 (`p1`)
  * dual BNC-Crocodile_clip

* Probes-2 (`p2`)
  * single BNC-BNC

* Oscillator(*osc*)
  * Sampling rate: 40 GHz
  * Bandwidth: 3.5 GHz
  
* Function generator(*fn*)
  * Sample rate: 500 MHz
  * Bandwidth:  40 MHz
  * Voltage for this test
    * v_pp: 1v
    * v_offset: 1.5v
  * Wave: 
    * sinusoid
    * square

### 1.1 Test 1
* Connect `p1` *osc* and *fn*
* Frequency(*freq*): 1M Hz
* *Osc* impedance: 1M ohm
* **We 1st test switch is this condition**

### 1.2 Test 2
* Connect `p2` between *osc* and *fn*
* Frequency(*freq*): 1M Hz
* *Osc* impedance: 1M ohm

## 2. Test ibert with optical moduld on VCU108(10 days)

* Starting test from 8/14 afternoon
* Shutting test result on 8/24 morning
