Pulse Repetition Rate: manually adjustable from 10 to 1000 Hz.
Pulse width: fixed, nonadjustable
Damping: 100© , 200© , 400© selectable to meet different resolution and sensitivity
need.
Probe work mode: Single element, dual element and through transmission;

RECEIVER
Real-time sampling at 160MHz high speed enough to record the defect information.
Rectification: Positive half wave, negative halfwave, full wave, and RF
DB Step: 0dB, 0.1 dB, 2dB, 6dB step value as well as auto-gain mode

ALARM
Alarm with sound and light, .
MERMORY
Total 100 configuration channels store all instrument operating parameters plus DAC/ AVG curve; stored configuration data can be easily previewed and recalled for quick, repeatable instrument setup. Total 1000 datasets store all instrument operating parameters plus A-scan. All the configuration channels and datasets can be transferred to PC via USB port.
FUNCTIONS
Peak Hold:
Automatically searching the peak wave inside the gate and hold it on the display. Equivalent diameter calculation: find out the peak echo and calculate its equivalent diameter. Continuous Record: Record the display continuously and save it to the memory inside the instrument.

Defect Localization: Localize the defect position, including the distance, the depth and its plane projection distance.
Defect Sizing: calculate the defect size
Defect Evaluation: Evaluate the defect by echo envelope.
DAC: Distance Amplitude Correction
AVG: Distance Gain Size curve function
Crack measure: Measure and calculate the crack depth
B-SCAN: Display the cross-section of the test block.

REAL-TIME CLOCK
Real time clock for tracking the time.
COMMUNICATION
USB2.0 high-speed communication port
