Pro-Itest High Speed cable tester
32-128Port (114GHz)
1. General Description
This document is describe the request of a new 32-128 port VNA Cable st Station for HS(MINI SAS/QSFP/SFP+), which is develop by Guangzhou Puqing Electronic chnology Co., LTD.(Puqing). The station shell perform the sting at frequencies up to 10G~28G/s (MBPS 114GHz).
To improve enterprise efficiency of high speed wire production, ensure product quality requirements, the test system combining with all kinds of instrument, control system, supporting software, accessories and so on a set of integrated automation solutions since 2010, and developed the first generation of test system, the company research and development innovation, constantly improve and optimize the software testing function, in August 2017 to launch a new generation test system (3.0), and greatly improve in the test efficiency, than the second generation of the system test speed increased by 40%, for the general customers high praise and recognition.

3. Assumptions & Comments
This proposal is valid with the following assumptions. If any of the assumptions are incorrect, Puqing is prepared to discuss and revise the quotation.
l shall supply at least one set of prepared Cable st Fixtures per st Station.
l shall supply multiple known-good “golden” cables with associad st data for st development (usable with provided Cable st Fixtures).
l shall supply all semi-flex cables required. 32-128 semi-flex cables from the RF switches to the supplied Prind Circuit Board (PCB) st Fixtures.
l Puqing shall shoulder the freight charges.
4. Proposed Solution
Puqing will develop a comple st sysm for , sysm include VNA instrument and 32-128 port RF Switch Box and software. The VNA instrument will select Keysight VNA, and 32-128 port RF Switch Box will made by Puqing.
The software shall control the RF Switch Box, VNA(suport R&S or Keysight), Controllable DC Supply Power etc, do a calibra, and perform an automatically VNA st, save st result in specify format.
The software also provide a st result manage sysm. The sysm include the st Result Manager Client and st Result Manager Server(st Result Manager Server not include in Cable st Station software, need pay separaly).
The compled st sysm shall contain the following functions at least:
l Control all necessary st equipment
l Calibra VNA and RF Switch Box
l Perform VNA automatically st
l Manager st Result(some of them need st Result Manager Server software)
u Zip st result file
u Upload st result file to file server
u Upload st result to SQL database
The compled st sysm shall perform the following measurements at least:
(Time Domain measurements)
l Single Trace Characristic impedance (T11, T22, T33, T44 [Ohms])
l Differential Impedance (TDD11, TDD22 [Ohms])
l Differential Propagation Delay (TDD21 [ns])
l Inr-pair Skew [ps]
l Intra-pair Skew [ps]

(Frequency domain measurements)
l Differential Insertion Loss (SDD21 [dB])
l Differential Return Loss (SDD11, SDD22 [dB])
l Common Mode Return Loss (SCC11, SCC22 [dB])
l Differential to Common mode Return Loss (SCD11, SCD22 [dB])
l Differential to Common mode conversion (SCD21 [dB])
l Differential to Common mode conversion – Differential IL (SCD21-SDD21 [dB])
l Differential Near- end Crosstalk (NEXT [dB])
l Differential Far-end Crosstalk (FEXT [dB])
l Total Power Sum Crosstalk (PSXT [dB])
l Insertion Loss to Crosstalk Ratio (ICR [dB])
l Insertion Loss Fitd Curve (ILfitd)
l Insertion Loss Deviation (ILD [dB])
l Ingrad Crosstalk Noise (ICN [mV])
l Single Ended Insertion Loss
l More Special Paramers required base on VNA sting ability
