+Rhode and Schwarz Presentations

+  
+
+Presentation 1: James 
+
+- EmC presentations - gtime FFT 
+    
+
+- Emissions 
+    
+
+Summary: 
+
+- Compliance testing is required for most electrical devices 
+    
+
+- Failure rate in full compliance is quite  high 
+    
+- Redesign + retest is retired 
+    
+
+- Precompliance testing is very important 
+    
+
+  
+
+Questions: 
+
+- Anyone melted a probe? (people have definitely melted antennas) 
+    
+
+  
+  
+

+  
+
+Signal Generators 
+
+  
+  
+
+Topics: 
+
+- Primary purpose of signal generators 
+    
+- Produces electrical wave forms of various a mplitudes, frequency and phase properties 
+    
+
+- Signal sinusoidal (CW - Continuous wave, SMW-2WA - the “flagship” Signal Generator) 
+    
+
+  
+
+Why are they important? 
+
+- They provide close to ideal input signals to the device under test (DUE_ 
+    
+- They emulate real-worls signals in the case of complex - moulations 5G, LTE, Wifi 
+    
+
+- Good performance ois important to minimize generators 
+    
+
+  
+  
+
+Signal Generators → 1. Analog Generators 2. Digital Generators 
+
+Analog Signal Generators 
+

+    
+
+  
+

+
+(insert image here)  
+
+  
+
+What do we need an analog generator for 
+
+- High quality singals 
+    
+- Reference code 
+    
+- Gain 
+    
+- Component development / testing (ADCD_ 
+    
+- Receiver testing 
+    
+- Military / radar applications 
+    
+
+  
+  
+  
+
+AM  Frequency modulation    FM frequency modulation Phase freqeuncy modulation 
+
+  
+  
+
+Analog Generator Selection Criterai -- things to consider 
+
+  
+
+Primary: 
+
+- Frequency range 
+    
+- Phase-noise 
+    
+- Harmonics 
+    
+- Output power 
+    
+
+  
+
+Secondaru 
+
+- Switching speeds 
+    
+- Frequency + amplitude accuracy 
+    
+- Very bad modulation support 
+    
+
+- Very important to understand your input signals 
+    
+
+  
+  
+
+Vector Signal Generator Applciations 
+
+- Receiver testing - a huge applications 
+    
+- Impairment generation 
+    
+- Impulse testing 
+    
+- Fading capbiliites, ability to generate attenuated delayed signals 
+    
+- Radar echo preparations (GNSS)
+    
+- Multipath signal generators
+    
+
+  
+  
+
+Vecotr Signal Basics: 
+
+- Analog signals defined by magnitude 
+    
+- Vector signals defined by: magnitude + phase 
+    
+
+- Used in digita modulation 
+    
+
+- LTE, SGNR, Wifi, Bluetooth, SatCOM 
+    
+
+  
+
+ASK, PSK, FSK 
+
+  
+
+Generating IQ Values 
+
+- Start with Symbol that represents particular magnitude _ phase 
+    
+- Magnitude + phase can be converted into can be converted into 
+    
+
+- In-phase (“real”) 
+    
+- Quadratic (“imaginary”) 
+    
+
+- Simplifies the pair of IQ vzlaues 
+    
+
+  
+
+IQ Modulatior 
+
+- Converts base band (transmitting) signals into RF Signals 
+    
+- This allows the AM FM PM to sum the signals 
+    
+
+  
+  
+
+IQ Modulation Steps  
+
+- Many licensing keys that you buy/input 
+    
+- ca n bring data in digitally (bring the IQ values in digitally) - various  ways to define the baseband 
+    
+- Can have a file of IQ values 
+    
+- Specific data that has been mapped to IQ values 
+    
+
+- Appropriate IQ values are generated based on what you selected 
+    
+- Seiteis fo steps involved in creating a vector modulated signal 
+    
+- Basic Digital Modulation - each variations of a signal magnitude _ phase represent a unique symbol 
+    
+
+-   
+    
+
+  
+  
+
+Each symbol  represents a specific  digital bit or combination of  bits  - 
+
+ASL - Amplitude  of  100%  and 50% 
+
+BPSK - phase 0 degrees and 180 degrees 
+
+  
+  
+  
+
+Constellations (Symbol Mapping) 
+
+- Constellations - collection of symbols on a polar chart representing a signal and magnitude and phase 
+    
+- X - acist depicting amplitude (I ) 
+    
+- Y -  as  depicting phase (Q) 
+    
+- ASK depicts 2 symbols with 1 bit of info - modulating in amplitude 
+    
+
+- BPSK chart depicts 2 symbols molulating only in phase 
+    
+
+  
+  
+
+How do we add more bits/symbols/information for faster data transmission? 
+
+- Through QAM symbol mapping 
+    
+- Could transmit only 1 bit previously can transmit 4 bits now! 
+    
+- These mits make up the frame of  our wifi, transmission, bluetooth, etc.. 
+    
+
+  
+  
+  
+  
+
+Modulation Bandwidth 
+
+- Some LTE at least 10 MHz of bandwidth requires 
+- Frequency - generators RF frequency , usually the carrier signal  
+- Bandwidth 
+- ** important tto distinguish what the signal rate is and what the bit-rate is **
+- Flatness is the gain variation of the  platform 
+    
+
+  
+
+Impairment Generation 
+
+- Another huge reason for vector 
+- previously  talked about band base generation  
+- Able to do fading and noise injection 
+    
+
+(include image here) 
+
+  
+  
+
+- impairment s emulate real-world effects 
+- Keeps up with standards as well 
+- Base band impairments - noise - SW interferes - impulse noise - phase noice - 
+- Fading - ability t o generate copies of a signal , attenuate them, or dopplegang them 
+    
+
+  
+  
+
+AWFN impairments 
+
+- Additive white gaissian noise additive -
+- Additive Combine dwith useful 
+- White: noise constant other frequency 
+- Gaussian - describes how noise changes over time ODFM (orthogonal) 
+- 23 ASK Constellations   ODFM orthogonal  
+- Considered more immune than QM 
+- Device under test → mini circuits amplification 
+
+  
+
+AWGN Generation 
+
+- Constellation drawn by the analyzer 
+    
+- Analyzer (receiver basically) no trouble achieving 
+    
+- Signal to rnoise ratio - APSK (PVB -52, Digital Viceo Broad cast 
+    
+- This  is  very important for devices that  are  re-timing the circuit 
+    
+- Needs to be able to filter out the (phase) noise that you inject 
+    
+
+  
+  
+
+Phase noise impairment:
+
+- Anything coming up in time domain (called jitter) 
+    
+- Anything long0term in time domain (called wonder) 
+    
+- Excessive phase noise can cause many issues 
+    
+- Disturbance  in communication systems for instance
+    
+- Phase noise can be addes to base bands signal by 
+    
+- Define amount of phase noise at gain  - frequency offsets 
+    
+- Adding phase noise to signal leads to rotation
+    
+- Errors → adjacent signal  /  symbols  bleeding into other symbols - bit-error 
+    
+
+  
+
+Impulse Noise impairment - many real wprld examples of impulse noise impairment 
+
+- unintentional - spark plugs motors, 
+    
+- Intentional - radars, or bursty , modulation time 
+
