USB-PD vs Type-C vs USB speeds• Is Type-C the same as USB-PD?
• Can Type-C not implement PD?
• Must USB 3.1 implement Type-C?
• Does USB 3.1 require PD?
• Can USB 2.0 implement Type-C?
• Does USB-PD require Type-C?
• Must a charger implement Type-C?
• How do you tell if a product has PD implemented?
• Can USB 3.0 implement Type-C?
• Will PD compliance be mandatory?
7
Type-C Power Delivery Testing
• 3 Chapters (PHY, Protocol, Power) in the Power Delivery Spec
responsible for:
• Charge devices up to 20V/5A/100W
• Cable functionality
• Provider/Consumer

• Compliance test capability for USB 3.1,
DisplayPort 1.3,
Thunderbolt 3, MHL
• Best signal integrity: 20 GHz bandwidth
(@-3dB), de-embeddable up to 30 GHz
• Type C plug interface fixture handling
connector “flip”
• Provides test point and probing access
for transmitter and power delivery
measurements
• Provides the elements to seamlessly
leverage Keysight’s portfolio of
compliance test applications

USB 3.1 Gen1/Gen2 Receiver Test Setup
Key capabilities:
• Analysis of coded & retimed data
• Support of 8b/10b and 128b/132b HW coding and decoding as well as HW scrambling
• Generates calibrated stress conditions for RX test (SSC, SJ, RJ, De-emphasis, ISI)
• Emulate LFPS 3-level signals with built-in electrical idle for loopback training and via channel
• Integrated Link Training, Tx Eq, Noise Impairment, Variable ISI, Receiver

New Compliance MethodologyChannel MetricsThere are three signal integrity impairments that impact the end-to-end link
performance: attenuation, reflection and crosstalk.
Reference: USB-IF Technical White Papers http://www.usb.org/developers/docs/whitepapers/
“Methodology Used to Determine SuperSpeed USB 10 Gbps (USB 3.1) - Gen2 Channel and Cable Assembly High Speed Compliance”
The channel metrics represents these three
impairments:
• Insertion loss fit at Nyquist frequency (ILfitatNq)
• Integrated multi-reflection (IMR)
• Integrated crosstalk (IXT)

Thunderbolt 3 Solutions
22
– Announced in Q2 2015
– Uses the Type-C connector
– Channel aggregation: two independent 20Gbps links into one logical
40Gbps link
– Supports other standards through ALT mode
– Cost competitive vs mult—chip, discrete, mux solutions
Thunderbolt 3 Overview
23
– PHY testing approach will be similar to Thunderbolt 2
• Tx, Rx, and Return Loss
Plus
• Type-C Power Delivery
• DP, USB over Type-C
– Customers with Thunderbolt DUTs need to work with their Intel PAE
or authorized test house for compliance certification
– Keysight can help with pre-compliance testing and is authorized in
CTS for TX, RX, and Return Loss.
