Rectiﬁcation

full-wave, positive half-wave, negative half-wave, RF display (up to 150 mm/5.9” steel)

Suppression

0 - 90 % linear

DAC/TCG

DAC with up to 16 curve points (reference reﬂectors), dynamic range 37 dB, maximum slope 6 dB/ms; 3 additional curves at adjustable dB distances, can be changed to TCG (Time-Corrected Gain) mode (horizontal recording threshold); meets national and international test speciﬁcations

DGS

recording curves for all valid equivalent reﬂector sizes and probes with DGS capability; setting as DAC or TCG; evaluation in dB related to curve, ERS or class (JIS); sound attenuation and transfer correction; reference reﬂectors used: backwall, circular disk reﬂector and side-drilled hole

Monitor gates

2 independent monitor gates, adjustable over the entire maximum calibration range; evaluation on the basis of A-scan at display refresh rate; gate alarm: off, coincidence, anticoincidence; visual and/or acoustic alarm

Distance measurement

individually selectable for each gate at the echo ﬂank or peak, in the RF mode addition-ally at the zero transition of the increasing or decreasing echo ﬂank

- initial pulse and measurement point in gate A or B

- measuring points: gate B - gate A (differential measurement)

Measurement resolution

sound path / time of ﬂight: up to 12.6 mm: 0.01 mm; other wise 0.2 % of display width

Amplitude

0.5 % screen height or 0.2 dB

A-scan digitization

1024 x 1024 pixels

Display freeze

static A-scan freeze, dynamic A-scan freeze (peak value, echo dynamics + real-time signal), average freeze via 2 to 32 ultrasonic pulse cycles

Echo comparison

simultaneous display of the currently active signal and a stored A-scan

Outputs

documentation via standard interfaces of the notebook

Inputs

2 analog inputs, e.g. for probe coordinates, digitization with 10 bits each

standard and dialog probes (automatic recognition) can be connected

Data storage

database for storing and managing instrument settings, test jobs and test results, including A-scan, DAC and alphanumeric comments, Export to Microsoft Excel; limited only by the hard disk size
