• Pulser: Spike excitation with a 180V pulse=10% into 50-ohm load @ 1KHz.
• Bandwidth: 1 to 20 MHz @ 3 dB.
• Preamp gain: 0 to 32 dB in 1 dB steps.
• Interface/monitor gains: 0 to 64 dB in 0.25 dB steps.
• Distance-amplitude correction: 0 to 40 dB via 256 linear ramps.
• Automatic gain control: Operates over the full monitor gain range with operator programmable limits.
• Thresholds: Dual-sensitivity from 1 to 100% in 1% steps.
• AScan signal monitoring: Either the raw RF or detected and filtered signal can be monitored using either an internal digitizer or an external standard oscilloscope; gate locations are included as part of the baseline signal.
• Analog output signal: A multiplexed analog output signal with a digital channel ID is available for each data channel for external monitoring of either the peak amplitude within the monitor gate or a thickness measurement.

• Surface echo-following gate: Echoes from any transducer channel can be used as the echo source for echo-following(EF). EF gate delay is adjustable from 32 nanoseconds to 540 microseconds in 8 nsec steps. EF gate width is adjustable from 32 nsec to 32 µsec in 8 nsec steps.
• Echo monitor gates: Unlimited gate intervals defined by software within two hardware monitor gates per transducer channel, all of which can be defined as positive or negative gates. The first hardware gate starts at the end of the surface echo following gate and is adjustable using a delay and a width parameter, both of which are adjustable from 32 nsec to 540 µsec in 8 nsec steps. A second hardware gate starts immediately at the end of the first hardware gate and is also adjustable from 32 nsec to 540 µsec in 8 nsec steps.
• Time of flight resolution: Time of flight values for up to 256 echoes can be latched with an 8 nanosecond resolution for each transducer channel which is active during a test cycle.
• Data processing algorithms: Each transducer channel uses the data channel microprocessor to implement proprietary data processing algorithms designed for the type of channel the transducer is programmed for in order to maximize the detection capability while also minimizing false defect indications.

• Inputs: 

• Optically isolated machine/sensor inputs are used to provide automatic cycle control.
• Two incremental or absolute encoder interfaces are provided for X,Y position and imaging, and are also used by the data processing algorithms for cross-channel correlation and pattern recognition applications.

• Outputs:

• Relay-driven and TTL-level outputs are available for implementing control signals for use in automatic cycle control, audible and visual alarms, GO/NO-GO test results, etc.
