CCBT20 High speed consumer cable tester

CCBT20 High speed consumer cable tester

- Series: High speed communication tester - Brand: Te-lead

The CCBT high-speed consumer cable tester allows testing of passive and active cables, including USB4 Type-C, Thunderbolt (TBT), DisplayPort (DP), and HDMI, as well as Active Optical Cables (AOC). This versatile product accommodates various cable versions and features eye measurement capabilities. It offers different bus transmission presets, receive equalization, and eye mask configurations. Test time for four lanes is below 10 seconds. Additionally, it includes unique functions such as insertion loss (IL) measurement for passive cables, low-speed lane continuity, bit error rate (BER) measurement on low-speed lanes, and power monitoring for active cables.

Product Overview


The CCBT is a high-speed consumer cable tester capable of measuring eye performance from 2 Gbps to 29 Gbps. It supports USB4 GEN2/3, DisplayPort 2.1, HDMI 2.1, and lower version buses. Users can select eye masks for USB4 GEN2/3 TP3, UHBR20_DPTx-TP3, and HDMI 2.1 FRL_12 TP2. The CCBT is suitable for both passive and active copper cables, as well as Active Optical Cables (AOC). It also monitors power consumption in active mode. Eye scanning is completed within 5 seconds through parallel measurement.

Power monitor

The power monitoring function is a valuable feature of this cable tester. Users can input power consumption specifications based on different standards to determine whether the cable passes or fails. Meanwhile, the GUI displays detailed information on voltage and current status.

Eye scan measurement

The eye scan is a key feature of the CCBT.  Eye opening can be measured for any data pattern. Users can select from standard masks or define custom masks within the built-in GUI. The GUI displays key eye parameters, including eye height, eye width, and jitter.  Mask-related production criteria can be used with both standard and custom masks.

With a built-in CDR, eye opening can be measured for any pattern. It uses different eye masks to calculate the mask margin for the product

High speed lane cross check

CCBT has HS cross check function which is easy to detect passive or active cable lane cross issue.

Signal process capability

Tx & Rx Equalizer: The CCBT high-speed cable tester allows for standard and custom Rx and Tx equalization settings, to meet the requirements of various bus standards. For example, it offers 15 presets for USB4 Tx with CTLE ranging from 0 to -9 dB. The CCBT has calibrated the eye diagram using a high-bandwidth real-time oscilloscope with different equalizations, demonstrating strong correlation with the oscilloscope's eye diagram.

Insertion Loss: The tester can assess the insertion loss of passive cables or LDR cables at specific frequencies for each lane.

Production test sequence

The GUI features multiple test modules (such as continuity, power monitoring, eye scan, etc.). Users can select the desired test modules and define the test parameters to create a setup for a specific type of cable, as illustrated in the photo labeled "test-10G." Different products will have unique test sequences based on the specified setup name.
