PULSER
Initial pulse filling frequency
(Selection of a frequency filling is determined by the testing task. Available 2 channels with different frequences);
0.5, 1, 2, 3, 4, 5, 6, 8 MHz;(up to 8 MHz available as an extra option)
Type of initial pulse: Toneburst Waveform;
Number of periods: 2-6;
Pulser amplitude: up to 2000 Vpp;
Pulse energy: depends on a filling frequency;
Pulse repetition frequency (PRF): from 50 to 4000 Hz;

RECEIVER
Gain adjustment: -20 to 68 dB (gain step 0.1, 0.5, 1, 2 dB);
Filter: 0.5, 1, 2, 3, 4, 5, 6 MHz;
Delay: from 0 to 1000 mm in steel (sound velocity 3230 m/s);
Range: from 1 tо 6000 mm in steel (sound velocity 3230 m/s);
Number of averages: 2 / 4 / 8 / 16 / 32;
Data presentation: А- Scan; B-Scan; C-Scan;

TCG
Depth: entire gain range;
Number of points: not less than 20;
Minimum time step between TCG points: up to 1 µs;
Maximum slope: not less than 46 dB/µs;
GATES
Two independent gates per channel Amplitude and time measurements
Two acceptance levels per gate
A/D converter: 10 bit, 80 MHz;
PORTS
(for communication with PC and various peripheral devices)
Ethernet (for communication with PC);

CONNECTORS
2 lemo00 connectors for connecting the EMAT to the receiver of EMA channel;
2 BNC connectors (one connector for the first pulsersecond connector for the second pulser).
lemo connector for Encoder connection;
1 power connector;
1 Ethernet connector for transmitting the data to PC;
1 Trigger connector is used either for synchronization between EMA channels, or for EMA channel metrological verification.
