– Key Features
The CTD55 automates comprehensive mobile phone evaluation through built-in test sequences that measure synchronization, location updates, call setup/clear-down, transmitter power control, handover operations, and receiver sensitivity. Measurement capabilities include bit error rate (BER), receive level, receive quality, phase and frequency error, power ramp versus time, timing error, and echo testing across voice paths, loudspeaker, and microphone circuits. Keypad function verification displays dialled numbers; device identity parameters (IMSI and IMEI) are displayed for validation.
Test reports are generated automatically, with Option CTD-B5 enabling enhanced analysis and direct printer output for immediate documentation. The intuitive interface requires no specialized knowledge—operators achieve clear Go/No-Go decisions through simple control sequences.
